The new drug approval page, shows these approved drugs in table, organised by year of approval. The majority of these drugs will be curated in the database, and if so they are hyperlinked to their respective summary pages from the INN in the table. There are some cases were we have listed an approved drug but it doesn&#8217;t have a link because it will not have been curated.</p> <p>&nbsp;</p> <div class="wordads-tag" data-slot-type="belowpost" style="display: none;"></div> </div><!-- end of .post-entry --> <div class="post-data"> Posted in <a href="https://blog.guidetopharmacology.org/category/chemical-curation/" rel="category tag">Chemical curation</a>, <a href="https://blog.guidetopharmacology.org/category/database-updates/" rel="category tag">Database updates</a>, <a href="https://blog.guidetopharmacology.org/category/technical/" rel="category tag">Technical</a> </div><!-- end of .post-data --> </div><!-- end of #post-4725 --> <div id="post-4678" class="post-4678 post type-post status-publish format-standard hentry category-chemical-curation category-database-updates category-technical"> <h1 class="post-title"><a href="https://blog.guidetopharmacology.org/2024/12/05/database-release-2024-4/" rel="bookmark">Database Release 2024.4</a></h1> <div class="post-meta"> <span class="meta-prep meta-prep-author posted">Posted on </span><a href="https://blog.guidetopharmacology.org/2024/12/05/database-release-2024-4/" title="10:51 am" rel="bookmark"><span class="timestamp">December 5, 2024</span></a><span class="byline"> by </span><span class="author vcard"><a class="url fn n" href="https://blog.guidetopharmacology.org/author/guidetopharmacology/" title="View all posts by guidetopharmacology">guidetopharmacology</a></span> <span class="comments-link"> <span class="mdash">&mdash;</span> <a href="https://blog.guidetopharmacology.org/2024/12/05/database-release-2024-4/#respond">Leave a comment</a> </span> </div><!-- end of .post-meta --> <div class="post-entry"> <p>The latest release (version 2024.4) of the IUPHAR/BPS Guide to Pharmacology database has been made.

Unfortunately, for many of these we are unable to provide sull chemical structures, and are restricted to the available nucleic acid sequence information. We have added new fields to present both the sequences and targets for each of these drugs. In line with all of our other approved drugs we curate approval information (dates, indications, trade names etc). We are continuing to add drugs from this class that are clinical candidates in phase 1-3 development.</p> <table border="1" width="906" cellspacing="0" cellpadding="0"> <tbody> <tr style="color: blue"

There were 414 INNs in this list. So far we have curated 27 kinase inhibitors from PL130, and where possible we have endeavoured to match the INNs to research codes in disclosed clinical pipelines, primary literature sources and clinical trials. We hope that this depth of curation provides additional insight and information for users of the GtoPdb. Occasionally the INNs match ligand structures that we have previously curated from other sources. Of note in PL130 was the inclusion of INNs for PROTAC type degrader molecules (zomiradomide, lirodegimod), and a kallikrein B1 gene editing agent (lonvoguran), both of which are relatively new classes of clinical interventions. We will continue to analyse this list to see if we can identify either new drug targets, or new pharmacological modalities for existing targets.</p> <p><b>Drug approvals</b></p> <p>Since the beginning of 2024 the FDA have approved 7 new drugs: as can be seen in the table below all but two of these are curated in the GtoPdb.</p> <table border="1" width="906" cellspacing="0" cellpadding="0"> <tbody> <tr style="color: blue" bgcolor="lightgrey"> <td valign="top" width="65"><strong>Ligand ID</strong></td> <td valign="top" width="100"><strong>INN</strong></td> <td valign="top" width="65"><strong>Indication</strong></td> </tr> <tr> <td align="left" valign="top">n/i</td> <td align="left" valign="top">berdazimer</td> <td align="left" valign="top">To treat molluscum contagiosum</td> </tr> <tr> <td align="left" valign="top"><a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=10772">10772</a>, <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=12188">12188</a></td> <td align="left" valign="top"><a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=10772">cefepime</a>, <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=12188">enmetazobactam</a></td> <td align="left" valign="top">To treat complicated urinary tract infections</td> </tr> <tr> <td align="left" valign="top">n/i</td> <td align="left" valign="top">letibotulinumtoxinA-wlbg</td> <td align="left" valign="top">To temporarily improve the appearance of moderate-to-severe glabellar lines</td> </tr> <tr> <td align="left" valign="top"><a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=9592">9592</a></td> <td align="left" valign="top"><a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=9592">tislelizumab-jsgr</a></td> <td align="left" valign="top">To treat unresectable or metastatic esophageal squamous cell carcinoma</td> </tr> <tr> <td align="left" valign="top"><a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=12026">12026</a></td> <td align="left" valign="top"><a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=12026">resmetirom</a></td> <td align="left" valign="top">To treat noncirrhotic non-alcoholic steatohepatitis with moderate to advanced liver scarring</td> </tr> <tr> <td align="left" valign="top"><a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=10070">10070</a></td> <td align="left" valign="top"><a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=10070">aprocitentan</a></td> <td align="left" valign="top">To treat hypertension</td> </tr> <tr> <td align="left" valign="top"><a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=7490">7490</a></td> <td align="left" valign="top"><a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=7490">givinostat</a></td> <td align="left" valign="top">To treat Duchenne muscular dystrophy in individuals aged 6 years and older</td> </tr> </tbody> </table> <p><em>n/i (not included_ as the agent does not meet the current criteria for inclusion in the GtoPdb.</em></p> <h3>Antibacterial Curation</h3> <p>Our collaboration with Antibiotic DB (ADB; <a class="ms-outlook-linkify" href="http://www.antibioticdb.com/" target="_blank" rel="noopener">www.antibioticdb.com</a>) continues to allow us to extend the coverage of ligands with annotated antibacterial activity in GtoPdb and provide comprehensive chemistry and pharmacology for select antibacterials curated within ADB, via reciprocal links.

2023/2024</h4> <p>For those new to a research topic, the Concise Guide allows a ready comparison of individual pharmacological targets within a family.</p> <p><strong>Overview – </strong>Each family is introduced with an Overview, which includes the nomenclature status of the family and general data, for example on the endogenous ligands for the particular receptor family.</p> <p><strong>Table of Targets –</strong> Each table of targets includes clickable links to HUGO Gene Nomenclature Committee (HGNC) and UniProt, free online databases of the gene and protein information.</p> <p>Where available, the table identifies the pharmacology (the most selective tools available) of that individual molecular target, with agonists, antagonists, substrates, products, and labelled ligands listed.</p> <p><strong>Comments sections </strong>underneath the tables identify generic or species variation and any association of targets with inherited disorders, together with any limitations of the pharmacological tools.</p> <p><strong>Further reading </strong>focusses on published reviews of the target family, highlighting the most relevant and recent publications, allowing the reader to identify further relevant resources for increasing the depth and breadth of their understanding.</p> <p><em>This post has been copied and re-produced from the British Journal of Pharmacology website

announcement <a href="https://globalbiodata.org/global-biodata-coalition-announces-outcome-of-2023-global-core-biodata-resource-selection-process/">here</a>.</p> <p>GtoPdb is proud to meet the stringent eligibility criteria that were part of the selection process. This covered scientific focus, size and reach of the user communities, quality of service, governance and impact on global research. </p> <p>The inclusion of the 15 new resources brings the total number of GCBrs to 52. The full list of GCBRs can be viewed <a href="https://globalbiodata.org/what-we-do/global-core-biodata-resources/list-of-current-global-core-biodata-resources/">here.</a></p> <blockquote> <p>The GBC defines biodata resources as any biological, life science, or biomedical database that archives research data generated by scientists, or functions as a knowledgebase by adding value to scientific data by aggregation, processing, and expert curation. Global Core Biodata Resources are biodata resources that are of fundamental importance to the wider biological and life sciences community and the long term preservation of biological data. They:</p> <ul> <li>provide free and open access to their data,</li> <li>are used extensively both in terms of the number and distribution of their users,</li> <li>are mature and comprehensive,</li> <li>are are considered authoritative in their field,</li> <li>are of high scientific quality, and</li> <li>provide a professional standard of service delivery.</li> </ul> <p>Through its GCBR designation, the GBC seeks to draw the attention of life science funders to the most critical of the global set of biodata resources and to better understand the challenges and needs for biodata resource long-term sustainability. The GCBRs are deposition databases and knowledgebases of fundamental importance to the global life sciences and biomedical research communities, providing open access and long-term preservation of key biological data. Sustained, long-term support for these databases is paramount, as their discontinuation would have a highly detrimental impact on the global research endeavour.</p> </blockquote> <p>&nbsp;</p> </div><!-- end of .post-entry --> <div class="post-data"> Posted in <a href="https://blog.guidetopharmacology.org/category/hot-topics/" rel="category tag">Hot Topics</a>, <a href="https://blog.guidetopharmacology.org/category/uncategorized/" rel="category tag">Uncategorized</a> </div><!-- end of .post-data --> </div><!-- end of #post-4604 --> <div id="post-4586" class="post-4586 post type-post status-publish format-standard hentry category-chemical-curation category-database-updates category-technical"> <h1 class="post-title"><a href="https://blog.guidetopharmacology.org/2023/11/29/database-release-2023-3/" rel="bookmark">Database Release 2023.3</a></h1> <div class="post-meta"> <span class="meta-prep meta-prep-author posted">Posted on </span><a href="https://blog.guidetopharmacology.org/2023/11/29/database-release-2023-3/" title="12:25 pm" rel="bookmark"><span class="timestamp">November 29, 2023</span></a><span class="byline"> by </span><span class="author vcard"><a class="url fn n" href="https://blog.guidetopharmacology.org/author/guidetopharmacology/" title="View all posts by guidetopharmacology">guidetopharmacology</a></span> <span class="comments-link"> <span class="mdash">&mdash;</span> <a href="https://blog.guidetopharmacology.org/2023/11/29/database-release-2023-3/#comments">1 Comment</a> </span> </div><!-- end of .post-meta --> <div class="post-entry"> <p>The latest release of the IUPHAR/BPS Guide to Pharmacology database was made on 29th November 2023.

The database update section of this paper focuses on two areas relating to important global health challenges. The first, SARS-CoV-2 COVID-19, remains a major concern and we describe our efforts to expand the database to include a new family of coronavirus proteins. The second area is antimicrobial resistance, for which we have extended our coverage of antibacterials in partnership with AntibioticDB, a collaboration that has continued through support from GARDP.</p> <p>In November, our latest Database Report became available, covering in more detail the work we have undertaken in terms of curation and development, alongside usage statistics in the last six months <a href="https://dev.guidetopharmacology.org/pdfs/GtoPdb_Database_Report_Nov_2023.pdf">GtoPdb_Database_Report_Nov_2023.pdf</a>.

Nsp13 is also reported to reduce the host interferon response, so limiting this effect would also likely contribute to COVID-19 therapeutic efficacy. To enhance nsp13&#8217;s inclusion we generated a new target entry (<a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=3261" target="_blank" rel="noopener noreferrer">nsp13</a>), to permit curation of quantitative ligand-target interaction data in the format used throughout other sections of the GtoPdb.</p> <p>Nsp13 modulators curated are:</p> <p><a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=10881" target="_blank" rel="noopener noreferrer">compound 16 [PMID: 31955138]</a></p> <p><a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=13022" target="_blank" rel="noopener noreferrer">compound 4b [Ramsey <i>et al</i>., 2023]</a></p> <p><a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=13028" target="_blank" rel="noopener noreferrer">compound 1b [PMID: 37562607]</a></p> <h3></h3> <h3>Antibacterial Curation</h3> <p>Our collaboration with Antibiotic DB (ADB; <a class="ms-outlook-linkify" href="http://www.antibioticdb.com/" target="_blank" rel="noopener">www.antibioticdb.com</a>) continues to allow us to extend the coverage of ligands with annotated antibacterial activity in GtoPdb and provide comprehensive chemistry and pharmacology for select antibacterials curated within ADB, via reciprocal links.

More significant modifications have been made to the summary pages for the <a href="https://www.guidetopharmacology.org/GRAC/FamilyDisplayForward?familyId=72">GABAA receptors</a> (in Ion channels) and <a href="https://www.guidetopharmacology.org/GRAC/FamilyDisplayForward?familyId=51">Orexin receptors</a> (in GPCRs). A major overhaul of the <a href="https://www.guidetopharmacology.org/GRAC/FamilyDisplayForward?familyId=117">Taste 2 GPCRs</a> (Bitter taste receptors) has been completed, with newly annotated details for ligands that interact with these receptors. We thank all of our contributors who have given so freely of their time to make these updates possible.</p> <p>As a regular review of the INN lists from the WHO, we added 31 new kinase inhibitors to the Guide (see table 1), that were included in the Jan 2023 list of proposed INNs (List 128). The chemical structures allowed us to connect around half of these (16/31) INNs to clinical leads (some with declared name&gt;structure), and others to patents from which we could obtain otherwise unpublished target information and interaction data. Five of the structures matched ligands that were already in the Guide. In total we have found interaction data for 27/31 of these inhibitors. For a few, we were unable to track down very little additional information.</p> <table style="height: 505px" border="1" width="928" cellspacing="0" cellpadding="0"> <tbody> <tr style="color: blue"

Women and men show an identical age-related decline, up to ~100 years old. The precision of the decline shows the limitations for therapy of aging. Mortality incidence for COVID19 shows a similar relationship. The authors propose that initial VO<sub>2</sub> max has a critical role in COVID sensitivity because of the direct relationship of disease severity with oxygen use, and the parallel decline in aging: mitochondria are targeted by viruses. The highest human recorded VO<sub>2</sub> max is 96, but is only 13 in nursing home residents, where metabolic capacity is massively reduced.</p> <p>Humans, with a long active life, may therefore have already optimised ageing and metabolism (2) compared to short-lived animals which are used in studies of anti-ageing drugs. </p> <p>As the results involve the very best age-related performances of humanity (by definition healthy), and there is absolute mathematical precision in the decline, there is no room for improvement, so drugs to slow ageing (apart from offsetting specific ageing-related diseases) may well remain a mirage. The results of the study are compatible with decline due to entropy, just a general disintegration, with different diseases developing by chance, heredity or the environment in a disintegrating body.</p> <p>Funding could be better spent on ensuring a humane and dignified exit at the end of life when metabolism breaks down completely. Nevertheless, exercise (such as 5000M parkruns) has been previously shown to extend active life by ~7 years (3).</p> <ol class="wp-block-list"><li>Spedding M, Marvaud R, Marck A, Delarochelambert Q, Toussaint JF.

After entering the blood, the virus rapidly multiplies to infect nearby cells. Endothelial cells line every blood vessel and have a surface area similar to a tennis court. These cells are especially vulnerable to virus infection as they express the the virus entry receptor, ACE2. Endothelial cells are also a source of&nbsp;endothelin-1 (ET-1), which is released in response to injury to cause long lasting vasoconstriction, reducing oxygen supply to vital organs.&nbsp;In the lungs, this can cause breathing difficulty, which in severe cases requires patients to be given oxygen and put on a ventilator.</p> <p>The study compared ET-1 in the plasma of patients infected with COVID-19 who were hospitalised during the first wave of the pandemic, including those placed on ventilators (1). Significantly higher levels of ET-1 were measured in these patients, compared with infected individuals with mild or no symptoms.&nbsp;The release of multiple copies of the virus following infection is known to damage endothelial cells and the results show stored ET-1&nbsp;is&nbsp;also released into the bloodstream.</p> <p>Currently, medicines that block the detrimental actions of ET-1 are used to treat rare forms of lung disease that share some of the clinical features of COVID-19 infection. The results provide evidence to support testing these medicines in clinical trials to see if they would benefit the most severely affected patients. The virus continues to evolve and in addition to vaccines and bespoke antivirals, that may be susceptible to the development of resistance, it is important to develop alternative ways to block the harmful actions of the virus. By targeting the damaging actions of SARS-CoV-2 on the host cells, medicines are likely to remain effective irrespective of evolving mutations in the virus.</p> <ol class="wp-block-list"><li>Abraham GR, Kuc RE, Althage M, Greasley PJ, Ambery P, Maguire JJ, Wilkinson IB, Hoole SP, Cheriyan J, Davenport AP.

As is well known though, it has recently gained additional scientific fame by also acting as a receptor for SARS-CoV-2. This study [1] compared the distribution in human tissue of ACE2 versus deltaACE2, a recently discovered truncated isoform that has lost the spike binding sites  for SARS-CoV-2, and is predicted to confer reduced susceptibility to viral infection. ACE2 was highly expressed in human lung, kidney, heart, liver and vasculature. However, deltaACE2 was the predominant protein alternative initiation variant in lung airway and liver bile duct epithelia, which may be a contributing factor to variation in response to the virus. A diagrammatic relationships of the full length and dACE is shown below. </p> <p></p> <figure class="wp-block-image size-large"><a href="https://blog.guidetopharmacology.org/wp-content/uploads/2022/02/image.png"><img data-attachment-id="4392" data-permalink="https://blog.guidetopharmacology.org/image/" data-orig-file="https://blog.guidetopharmacology.org/wp-content/uploads/2022/02/image.png" data-orig-size="397,499" data-comments-opened="1" data-image-meta="{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}" data-image-title="image" data-image-description="" data-image-caption="" data-medium-file="https://blog.guidetopharmacology.org/wp-content/uploads/2022/02/image.png?w=239" data-large-file="https://blog.guidetopharmacology.org/wp-content/uploads/2022/02/image.png?w=397" loading="lazy" width="397" height="499" src="https://blog.guidetopharmacology.org/wp-content/uploads/2022/02/image.png?w=397" alt="" class="wp-image-4392" srcset="https://blog.guidetopharmacology.org/wp-content/uploads/2022/02/image.png 397w, https://blog.guidetopharmacology.org/wp-content/uploads/2022/02/image.png?w=119 119w, https://blog.guidetopharmacology.org/wp-content/uploads/2022/02/image.png?w=239 239w" sizes="(max-width: 397px) 100vw, 397px" /></a></figure> <p>The discovery of this novel short dACE2 variant in two independent reports may have important implications in COVID-19 research. It is enzymatically inactive, and the absence of the spike binding domains of the full-length ACE2 suggests dACE2 does not bind SARS-CoV-2 spike protein. It is still unclear what the precise effects of such an alternative form are in both normal physiology and in relation to SARS-CoV-2 infection and Long COVID, but the ratio of dACE2 versus the full-length protein may be a contributing factor in the wide inter-individual variation in response to COVID-19</p> <ol class="wp-block-list" type="1"><li>Williams TL, Strachan G, Macrae RGC, Kuc RE, Nyimanu D, Paterson AL, Sinha S, Maguire JJ, and Davenport AP.

Continued advances in the molecular understanding of cancer, multiple approaches to drug design, and the increasing number of resolved kinase structures (1) have facilitated the development of kinase inhibitors with improved potency, selectivity, and efficacy.</p> <p>Two new analyses published in <em>Nature Reviews Drug Discovery</em> present the historical development of kinase inhibitors as well as the current outlook on kinase drug discovery. Cohen et al. (1) present a detailed study on FDA-approved small molecular weight kinase inhibitors titled <em>Kinase drug discovery 20 years after imatinib: progress and future directions</em>. The analysis encompasses the pivotal events in kinase inhibitor development and remarkable progress made over the past 20 years in improving the potency and specificity of small molecule kinase inhibitors (SMKIs) and the kinase pathways targeted in drug discovery. Importantly, the development of drug resistance to kinase inhibitors and how these challenges are being met in the future of kinase drug discovery are discussed.</p> <p>The new analysis <em>Trends in kinase drug discovery: targets, indications and inhibitor design</em> published this month by Attwood et al. (2) analyses the landscape of approved and investigational therapies targeting kinases and trends within it, including the most popular targets of kinase inhibitors and their expanding range of indications. Furthermore, strategies for kinase inhibitor design, including the development of allosteric and covalent inhibitors, bifunctional inhibitors, and chemical degraders are discussed. Since the approval of fasudil in 1995, the number of approved kinase inhibitors worldwide as increased to 98 drugs, of which 71 are SMKIs and 10 monoclonal antibodies approved by the FDA. Remarkably, the number of FDA-approved SMKIs has more than doubled in the past five years and they constitute ~15% of all novel drug approvals by the FDA. While oncology is still the predominant area for their application, there have been important approvals for indications such as rheumatoid arthritis, and one-third of the SMKIs in clinical development address disorders beyond oncology. Nearly 600 investigational kinase-targeting agents that were registered in ClinicalTrials.gov were included this analysis, consisting of 475 novel SMKIs and 124 biological agents. Information on clinical trials of SMKIs reveals that ~110 novel kinases are currently being explored as targets, which together with the ~45 targets of approved kinase inhibitors represent only ~30% of the human kinome (4), indicating that there are still substantial unexplored opportunities for this drug class.</p> <p>In summary, although there have been substantial advances in kinase drug discovery, there are still many challenges and opportunities in this field. The potential for developing novel types of kinase inhibitors is large and it is expected that this will continue to be a major area of growth in the next 20 years.</p> <p><strong>Comments by Misty Attwood and <a href="https://www.guidetopharmacology.org/GRAC/ContributorDisplayForward?contributorId=311">Helgi Schiöth</a>,&nbsp;</strong>University of Uppsala, Uppsala, Sweden.

It blocks production of inflammatory cytokines in infected cell cultures.</p> <div class="wp-block-image"> <figure class="alignleft size-large"><img data-attachment-id="4233" data-permalink="https://blog.guidetopharmacology.org/11421/" data-orig-file="https://blog.guidetopharmacology.org/wp-content/uploads/2021/02/11421.gif" data-orig-size="309,180" data-comments-opened="1" data-image-meta="{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}" data-image-title="11421" data-image-description="" data-image-caption="" data-medium-file="https://blog.guidetopharmacology.org/wp-content/uploads/2021/02/11421.gif?w=300" data-large-file="https://blog.guidetopharmacology.org/wp-content/uploads/2021/02/11421.gif?w=309" loading="lazy" width="309" height="180" class="wp-image-4233 aligncenter" src="https://blog.guidetopharmacology.org/wp-content/uploads/2021/02/11421.gif?w=309" alt="" srcset="https://blog.guidetopharmacology.org/wp-content/uploads/2021/02/11421.gif 309w, https://blog.guidetopharmacology.org/wp-content/uploads/2021/02/11421.gif?w=150 150w, https://blog.guidetopharmacology.org/wp-content/uploads/2021/02/11421.gif?w=300 300w" sizes="(max-width: 309px) 100vw, 309px" /> <figcaption>2D structure of emvododstat</figcaption> </figure> </div> <p>&nbsp;</p> <p>&nbsp;</p> <p>&nbsp;</p> <p>&nbsp;</p> <p>&nbsp;</p> <p>&nbsp;</p> <p><strong><span style="text-decoration:underline;">Ligand ID: 11470</span></strong><br />Names: <strong>ensovibep (MP0420)</strong><br />Comment: MP0420 is a DARPin that binds to the SARS-CoV-2 spike glycoprotein, and offers virus neutralising potential. It is being progressed to clinical trial by Molecular Partners and Novartis. DARPins are protein-based therapeutics, with the high selectivity and affinity of antibodies, but are around 10% of the size. They are easier to manufacture than whole antibodies, and may be suitable for subcutaneous administration rather than infusion. Molecular Partners have developed two multi-valent DARPins that are designed to engage multiple sites of the SARS-CoV-2 spike glycoprotein. Novartis and Molecular Partners are working together on both MP0420 and MP0423 for COVID-19.</p> </div><!-- end of .post-entry --> <div class="post-data"> Tagged with: <a href="https://blog.guidetopharmacology.org/tag/coronavirus/" rel="tag">coronavirus</a>, <a href="https://blog.guidetopharmacology.org/tag/pre-release-ligands/" rel="tag">pre-release ligands</a><br /> Posted in <a href="https://blog.guidetopharmacology.org/category/uncategorized/" rel="category tag">Uncategorized</a> </div><!-- end of .post-data --> </div><!-- end of #post-4222 --> <div id="post-4182" class="post-4182 post type-post status-publish format-standard has-post-thumbnail hentry category-hot-topics"> <h1 class="post-title"><a href="https://blog.guidetopharmacology.org/2021/01/22/hot-topics-gene-symbol-usage-and-the-need-to-do-better/" rel="bookmark">Hot Topics: Gene Symbol usage and the need to do&nbsp;better</a></h1> <div class="post-meta"> <span class="meta-prep meta-prep-author posted">Posted on </span><a href="https://blog.guidetopharmacology.org/2021/01/22/hot-topics-gene-symbol-usage-and-the-need-to-do-better/" title="1:03 pm" rel="bookmark"><span class="timestamp">January 22, 2021</span></a><span class="byline"> by </span><span class="author vcard"><a class="url fn n" href="https://blog.guidetopharmacology.org/author/guidetopharmacology/" title="View all posts by guidetopharmacology">guidetopharmacology</a></span> <span class="comments-link"> <span class="mdash">&mdash;</span> <a href="https://blog.guidetopharmacology.org/2021/01/22/hot-topics-gene-symbol-usage-and-the-need-to-do-better/#respond">Leave a comment</a> </span> </div><!-- end of .post-meta --> <div class="post-entry"> <a href="https://blog.guidetopharmacology.org/2021/01/22/hot-topics-gene-symbol-usage-and-the-need-to-do-better/" title="Hot Topics: Gene Symbol usage and the need to do&nbsp;better" > <img width="311" height="255" src="https://blog.guidetopharmacology.org/wp-content/uploads/2021/01/capture-e1613731556638.jpg?w=311" class="attachment-post-thumbnail size-post-thumbnail wp-post-image" alt="" decoding="async" loading="lazy" srcset="https://blog.guidetopharmacology.org/wp-content/uploads/2021/01/capture-e1613731556638.jpg 311w, https://blog.guidetopharmacology.org/wp-content/uploads/2021/01/capture-e1613731556638.jpg?w=150 150w, https://blog.guidetopharmacology.org/wp-content/uploads/2021/01/capture-e1613731556638.jpg?w=300 300w" sizes="(max-width: 311px) 100vw, 311px" data-attachment-id="4204" data-permalink="https://blog.guidetopharmacology.org/2021/01/22/hot-topics-gene-symbol-usage-and-the-need-to-do-better/capture-18/" data-orig-file="https://blog.guidetopharmacology.org/wp-content/uploads/2021/01/capture-e1613731556638.jpg" data-orig-size="311,255" data-comments-opened="1" data-image-meta="{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}" data-image-title="Capture" data-image-description="" data-image-caption="" data-medium-file="https://blog.guidetopharmacology.org/wp-content/uploads/2021/01/capture-e1613731556638.jpg?w=300" data-large-file="https://blog.guidetopharmacology.org/wp-content/uploads/2021/01/capture-e1613731556638.jpg?w=311" /> </a> <p>The GtoPdb team need no convincing about the importance of eliminating equivocality in gene and gene product names, as they are used in the pharmacology, chemical biology and drug discovery literature. Crucially, this also applies to their inclusion in curated database bioactivity records such as GtoPdb. We were thus particularly pleased to see &#8220;<strong>Standardizing gene product nomenclature</strong>&#8221; that appeared recently in PNAS [1]. This included not only an honourable mention of the Nomenclature Committee of the International Union of Basic and Clinical Pharmacology (NC-IUPHAR) but also the citation of our most recent Concise Guide Introduction [2]. </p> <p>The collaboration between NC-IUPHAR and HGNC for standardising the nomenclature of pharmacological targets goes back well over a decade. This has been (and continues to be) an iterative process whereby NC (after extensive consultation) recommends naming schema for certain target classes that are different to those approved by HGNC. This is typically done on the basis of well established publication usage in the pharmacological community. In many cases these older protein family names predate completion of the human genome. This can be illustrated for the case of the <a href="https://www.guidetopharmacology.org/GRAC/FamilyDisplayForward?familyId=80">Voltage-gated calcium channels </a> as shown in the GtoPdb family page below.</p> <p><img data-attachment-id="4204" data-permalink="https://blog.guidetopharmacology.org/2021/01/22/hot-topics-gene-symbol-usage-and-the-need-to-do-better/capture-18/" data-orig-file="https://blog.guidetopharmacology.org/wp-content/uploads/2021/01/capture-e1613731556638.jpg" data-orig-size="311,255" data-comments-opened="1" data-image-meta="{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}" data-image-title="Capture" data-image-description="" data-image-caption="" data-medium-file="https://blog.guidetopharmacology.org/wp-content/uploads/2021/01/capture-e1613731556638.jpg?w=300" data-large-file="https://blog.guidetopharmacology.org/wp-content/uploads/2021/01/capture-e1613731556638.jpg?w=311" class="wp-image-4204" style="width:900px;" src="https://blog.guidetopharmacology.org/wp-content/uploads/2021/01/capture.jpg" alt=""></p> <p>As we can see in the page for <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=528&amp;familyId=80&amp;familyType=IC">Cav1.1</a> curation adds a full set of synonyms including CACNA1S and &#8220;calcium voltage-gated channel subunit alpha1 S&#8221; as approved <a href="https://www.genenames.org/data/gene-symbol-report/#!/hgnc_id/HGNC:1397">HGNC Symbol and name</a>, respectively.

<div class="post-entry"> <p>Historically, the main classes of drug targets have been receptors, enzymes, ion channels and transporters which are primarily targeted by small molecules. However, advances in molecular biology, genomics, and pharmacology have facilitated the development of different therapeutic modalities which in turn have broadened the types of drug targets. In particular, soluble ligands have growing interest as targets and now constitute 10% of novel targets in clinical trials and are currently the third-largest target class of therapeutic agents targeting human protein products, after enzymes and receptors [1].</p> <p>A new analysis of ligand-targeting [2], illustrates the different classes of ligand-targeting drugs and targets as well as analysing the success of the different technology platforms. This emerging class of drug targets is very dynamic with 291 agents that target 99 unique ligands reaching clinical development from 1992 to 2020. In the last five years, the number of ligand-targeting agents which are FDA-approved has doubled to 34, while the number of clinically validated ligand targets has doubled to 22. Therapeutic antibodies are the most common class of both approved and investigative ligand-targeting agents, followed by decoy receptors. Several technology platforms are successfully being developed, enhancing the opportunities of drug development using antibody fragments, single-domain antibodies, aptamers, spiegelmers, engineered protein scaffolds, gene therapy, therapeutic vaccines and oligonucleotides. There is an increase in the number of agents that target more than one ligand, as well as the number of unique combinations of ligands. Advances in engineering technology and the ability to effectively and safely target more than one ligand has combined with increased knowledge of disease pathways to effectively utilize bispecific antibodies and decoy receptors, amongst others, to selectively disrupt multiple biological pathways by blocking two (or more) related or unrelated ligands. Cytokines and growth factors are the predominant types of targeted ligands (70%), which is consistent with the three major disease groups being treated by both approved and investigational agents: inflammation and autoimmune diseases, cancer, and ophthalmological diseases.</p> <p>Several factors contribute to the increasing importance of soluble ligands as drug targets, including the growing understanding of the role of the immune system in many diseases in conjunction with the tractability of cytokines as therapeutic agents, and the relative accessibility of ligands in comparison to their receptors to therapeutic agents. Given the increasing body of evidence that inflammation is involved in many diseases beyond typical inflammation disorders and the position of ligand-targeting drugs at the forefront of anti-inflammatory therapies, there will be continued interest in this class of agents. Furthermore, there is vast territory to explore in the ligand target landscape, as there are almost 600 endogenous human peptides according to IUPHAR/BPS Guide to PHARMACOLOGY (<a href="https://www.guidetopharmacology.org">https://www.guidetopharmacology.org</a>) with approximately 150 of these identified as having specifically curated immunopharmacological data associated with them (IUPHAR Guide to IMMUNOPHARMACOLOGY: <a href="https://www.guidetoimmunopharmacology.org/immuno/">https://www.guidetoimmunopharmacology.org/immuno/</a>).</p> <p>In conclusion, ligands as a type of drug target now merit consideration as a distinct and expanding group of targets for a range of therapeutic modalities that can exert their effects through single targets or selected combinations.</p> <p><strong>Comments by Misty Attwood and <a href="https://www.guidetopharmacology.org/GRAC/ContributorDisplayForward?contributorId=311">Helgi Schiöth</a>, </strong>University of Uppsala, Uppsala, Sweden.

It targets viral RNA-dependent RNA polymerase (RdRP) of RNA viruses and since the catalytic domain of RdRP is well conserved across species, has a broad-spectrum of activity; although Furuta <i>et al</i>. (2002) reported that actvity was weak against non-influenza virus RNA viruses [<a title="4. Furuta Y, Takahashi K, Fukuda Y, Kuno M, Kamiyama T, Kozaki K, Nomura N, Egawa H, Minami S, Watanabe Y et al.. (2002) Antimicrob. Agents Chemother. 46 (4): 977-81">4</a>]. Favipiravir was originally identified through a chemical library screen against influenza virus RdRP [<a title="3. Furuta Y, Komeno T, Nakamura T. (2017) Proc. Jpn. Acad., Ser. B, Phys. Biol. Sci. 93 (7): 449-463">3</a>]. Chemically, it is a prodrug. In human cells it undergoes phosphoribosylation and phosphorylation to its active form, favipiravir-ribofuranosyl-5′-triphosphate (F-RTP). F-RTP is bound by the RdRP, but it blocks enzyme activity and so terminates chain elongation [<a title="5.

Besides their important physiological roles, these modulating proteins are also potential targets for drug discovery. <a href="https://www.guidetopharmacology.org/GRAC/FamilyDisplayForward?familyId=77">P2X receptors</a> are LGICs for which ATP is the endogenous agonist. Seven P2X subunits have been identified and they form trimers to produce at least twelve different receptor subtypes. Here, the authors combined a genome-wide open reading frame (ORF) collection with high-throughput functional screening, to search for P2X receptor modulators.</p> <p>They first created a HEK-293 cell line that stably expressed human <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=479&amp;familyId=77&amp;familyType=IC">P2X2</a> plus <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=480&amp;familyId=77&amp;familyType=IC">P2X3</a> receptors, then one-by-one, co-expressed each of 17,284 non-redundant ORFs, which represents 90% of the known human protein-coding genes. They then compared the rise in intracellular [Ca<sup>2+</sup>] induced by the P2X3 agonist <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=4093">α,β-meATP</a>, using a composite score of four measurements; 1) baseline, 2) peak and 3) steady-state [Ca<sup>2+</sup>], along with 4) time-course of the decay of the peak. The highest scoring ORFs were then co-expressed with P2X3 receptors in <em>Xenopus laevis</em> oocytes and their effects on ATP-induced ion currents determined. This process led to <a href="https://www.uniprot.org/uniprot/Q8TC26">TMEM163</a> being identified as a modulator of P2X3 receptors.</p> <p>TMEM163 comprises 289 amino acids, with a molecular weight of 31 kDa and predicted secondary structure of six transmembrane-spanning domains with intracellular NH<sub>2</sub>&#8211; and COOH-termini. When expressed on its own, TMEM163 had no ATP-dependent activity and when co-expressed, had no effect on the activity of AMPA, kainate, muscarinic or P2X2 receptors, nor on endogenous P2Y receptors in HEK-293 cells. It did, however, potentiate ATP-evoked currents mediated by <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=478&amp;familyId=77&amp;familyType=IC">P2X1</a> and <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=481&amp;familyId=77&amp;familyType=IC">P2X4</a> receptors and conversely, inhibited currents carried by <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=484&amp;familyId=77&amp;familyType=IC">P2X7</a> receptors. Thus TMEM163 appears to selectively modulate P2X receptor activity, but in a subtype-specific manner.</p> <p>More detailed analysis of its actions showed that TMEM163 potentiated P2X3 receptors by shifting the ATP concentration-response curve (CRC) to the left, with a five-fold decrease in the EC<sub>50</sub> and slowing the time-course of current decay. Surprisingly, it also substantially reduced the surface expression of P2X3 receptors. In contrast, the inhibitory effects on P2X7 receptors were associated with a decrease in both the potency of ATP and surface expression of the receptor.</p> <p>Next, the expression and effects of native TM163 was investigated in mice. <em>In situ</em> hybridisation and an anti-TM163 antibody showed TMEM163 to be present in primary cultures of mouse cerebellar neurones. Infection with a TMEM163 shRNA reduced protein expression by almost half and the peak amplitude of ATP-induced ion currents by a third. The effect on P2X3 receptor protein levels was not reported, however. To study its role <em>in vivo</em>, TMEM163 was knocked-out using CRISPR/Cas9 and pain-associated behaviour induced by ATP injection into the hind-paw studied. There was no difference in paw lifting between wild-type and knock-out mice, but freezing behaviour was reduced by about 50%. Notably, and in contrast to the data obtained using recombinant TMEM163, the total amount of P2X3 protein in dorsal root ganglion was unchanged. The ATP CRC was, however, shifted about five-fold to the right by TMEM163 knock-out, consistent with the leftwards shift seen using the recombinant proteins.</p> <p>By showing that that TMEM163 selectively modulates P2X receptor activity and in a subtype-specific manner, this study greatly improves our understanding of how native P2X receptors function. As such, TMEM163 is potentially a new target for drug discovery.</p> <p><strong>Comments by <a href="https://www.guidetopharmacology.org/GRAC/ContributorDisplayForward?contributorId=297">Charles Kennedy</a></strong>, Strathclyde Institute of Pharmacy and Biomedical Sciences, University of Strathclyde, Glasgow, UK.

This remains so,  despite decades of  intense effort from not only all major pharmaceutical companies but also academic groups utilising various flavours of  de-orphanistaion screening approaches and technologies. This was pursued in parallel with cloning (and patenting) the complete repertoire of human GPCRs as they slowly came into view.  Initially done via mining millions of expressed sequence tag (EST) transcripts in the mid 90&#8217;s, this later shifted focus to genomic DNA  surfacing between appropriately 1998 and 2000. The modest progress even after the completion of the draft human genome can be discerned from the table below compiled in 2000 [4].</p> <p><img data-attachment-id="3981" data-permalink="https://blog.guidetopharmacology.org/2020/05/17/hot-topics-a-gpcr-triple-for-peptides/capture-10/" data-orig-file="https://blog.guidetopharmacology.org/wp-content/uploads/2020/05/capture.jpg" data-orig-size="509,389" data-comments-opened="1" data-image-meta="{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;cdsoutharn&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;1589754517&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}" data-image-title="Capture" data-image-description="" data-image-caption="" data-medium-file="https://blog.guidetopharmacology.org/wp-content/uploads/2020/05/capture.jpg?w=300" data-large-file="https://blog.guidetopharmacology.org/wp-content/uploads/2020/05/capture.jpg?w=509" loading="lazy" class=" size-full wp-image-3981 aligncenter" src="https://blog.guidetopharmacology.org/wp-content/uploads/2020/05/capture.jpg" alt="Capture" width="509" height="389" srcset="https://blog.guidetopharmacology.org/wp-content/uploads/2020/05/capture.jpg 509w, https://blog.guidetopharmacology.org/wp-content/uploads/2020/05/capture.jpg?w=150&amp;h=115 150w, https://blog.guidetopharmacology.org/wp-content/uploads/2020/05/capture.jpg?w=300&amp;h=229 300w" sizes="(max-width: 509px) 100vw, 509px" /></p> <p>Progress ~ 2000- 2018 is outlined both in  Concise Guide 2019/20 : G Protein-Coupled Receptors (<a href="https://www.ncbi.nlm.nih.gov/pubmed/31710717">PMID: 31710717</a>)  [5] and in the Guide to Pharmacology <a href="https://www.guidetopharmacology.org/latestPairings.jsp">latest parings list </a>.</p> <p>As the first of this trio of papers, Foster et al.  [1] have significantly advanced the de-orphanisation field in 2019 by integrating computational and experimental approaches for peptide-GPCR pairings.  They began with comparative sequence and structural analyses to gain biological insights into the  human peptide-receptor signalling landscape. They were then able to leverage these features to mine candidate peptide ligands from the entire human genome,  arranged for these to be synthesised and then tested for activity in a broad range of pairing assays that included known ligands as positive controls.  The impressive scope of  results is indicated  in their Fig 7 (below).</p> <p><img data-attachment-id="3991"

signaling network from 348 to 407 interactions.  It is also important to note that they were unable to reproduce no less than six reported parings in the literature from 2004 to 2016 (i.e. those de-orphanisations could not be verified).</p> <p>In collaboration with the Copenhagen crew, this paper was curated by the GtoPdb team according to their target mapping stringency and potency thresholds.  Consequently, 11 new peptides have been  annotated with the quantitative ligand binding data reported for the newly de-orphanised receptors.  These are shown below with their PubChem <a

this trio is an in-depth review by Davenport et. al.

This may even eventually extent to analogues of the peptides from the first two papers perhaps even related to new de-orphanisations.  As detailed in this review therapeutic peptides have recently been  undergoing a development technology renaissance via half- life extension, stapling and resistance to proteolysis. These measures  improve pharmacokinetics and oral bioavailability that have hitherto been much less favourable for peptidic structures in comparison to conventional small-molecule drug candidates.  An overview of these peptide approvals and advanced candidates is taken from their Figure 1.</p> <p><img data-attachment-id="4014" data-permalink="https://blog.guidetopharmacology.org/2020/05/17/hot-topics-a-gpcr-triple-for-peptides/capture-17/" data-orig-file="https://blog.guidetopharmacology.org/wp-content/uploads/2020/05/capture-7.jpg" data-orig-size="1004,706" data-comments-opened="1" data-image-meta="{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;cdsoutharn&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;1590064573&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}" data-image-title="Capture" data-image-description="" data-image-caption="" data-medium-file="https://blog.guidetopharmacology.org/wp-content/uploads/2020/05/capture-7.jpg?w=300" data-large-file="https://blog.guidetopharmacology.org/wp-content/uploads/2020/05/capture-7.jpg?w=605" loading="lazy" class="alignnone size-full wp-image-4014" src="https://blog.guidetopharmacology.org/wp-content/uploads/2020/05/capture-7.jpg" alt="Capture" width="1004" height="706" srcset="https://blog.guidetopharmacology.org/wp-content/uploads/2020/05/capture-7.jpg 1004w, https://blog.guidetopharmacology.org/wp-content/uploads/2020/05/capture-7.jpg?w=150&amp;h=105 150w, https://blog.guidetopharmacology.org/wp-content/uploads/2020/05/capture-7.jpg?w=300&amp;h=211 300w, https://blog.guidetopharmacology.org/wp-content/uploads/2020/05/capture-7.jpg?w=768&amp;h=540 768w" sizes="(max-width: 1004px) 100vw, 1004px" /></p> <p>This comprehensive review goes on to describe in detail 26 synthetic peptides  approved for clinical use  (20 agonists and 6 competitive antagonists) targeting eight class A receptor families.  It also includes a useful  structural perspectives not only on peptide binding sites but also addresses the frequently overlooked aspects associated with unnatural amino acids and chemical modifications.</p> <p>It seems somewhat anachronistic  that the  <em>Nat Rev Drug Discov</em>  PDFs are entity link-free zones (although this <a href="https://www.go-fair.org/fair-principles/">FAIR</a>-gap  has been pointed out to them).  Notwithstanding, the GPCR names should retrieve cleanly from GtoPdb and GPCRdb.  Most of the peptide names in the review should also retrieve their ligand entries from GtoPdb but these will eventually be cross-checked both for the resolution of equivocalities and addition of new development candidates with referenced binding data.</p> <p>Constituting a well-referenced overview of  the field, these three papers also represent  &#8220;good news&#8221; for peptides and their analogues.  Notwithstanding,  this <a href="https://www.slideshare.net/cdsouthan/peptide-tribulations-234339858">slide set</a> outlines some of the challenges for curating peptides and searching them in databases.</p> <p style="text-align:center;">**********************************</p> <p>Comments by <strong>Chris Southan</strong>, Fellow of the University Edinburgh,  Owner of TW2Informatics ,  Chair of NC-IUPHAR Subcommitees for Proteases and  Drug Targets and Chemistry (DRUTACS),  ORCID 0000-0001-9580-0446.  As declaration of interest (but not conflict!)  Chris was pleased to be a co-supervisor for Alex Hauser&#8217;s PhD work on <a href="https://dra.ku.dk/activities/2019/phd-defences/alexander_hauser/">Computational Receptor Biology</a></p> <p>[1] <strong>Discovery of Human Signaling Systems: Pairing Peptides to G Protein-Coupled Receptors</strong>.  Foster SR, Hauser AS, Vedel L, Strachan RT, Huang XP, Gavin AC, Shah SD, Nayak AP, Haugaard-Kedström LM, Penn RB, Roth BL, Bräuner-Osborne H, Gloriam DE. <em>Cell.</em> <strong>2019</strong> Oct 31;179(4):895-908.e21. doi: 10.1016/j.cell.2019.10.010.  <a href="https://www.ncbi.nlm.nih.gov/pubmed/31675498">PMID: 31675498.</a></p> <p>[2]  <strong>Novel approaches leading towards peptide GPCR de-orphanisation</strong>.  Hauser AS, Gloriam DE, Bräuner-Osborne H, Foster SR. <em>Br J Pharmacol</em>. <strong>2020</strong> Mar;177(5):961-968. doi: 10.1111/bph.14950.

It is a potent and selective direct inhibitor of coagulation factor Xa that is delivered intravenously. The INN record stipulates the (2R,3R) configuration. Virtual docking studies suggest that otamixaban may bind to the serine protease <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=2421" target="_blank" rel="noopener">TMPRSS2</a>, which is linked to host cell entry by a number of viruses, in particular influenza viruses and respiratory viruses such as SARS-CoV-2. Inhibition of TMPRSS2 is being examined for antiviral activity. The TMPRSS2 inhibitory potential and/or antiviral activity of otamixaban have not yet been determined.</li> </ul> </li> </ul> </li> </ul> <hr /> <ul> <li><a name="10733"></a>Ligand ID: 10733 <ul> <li>Name: <strong>I-432</strong></li> <li><img src="https://www.guidetopharmacology.org/CHEMSTRUCT/iuphar/10733.gif" alt="Click here for structure editor" /></li> <li>IUPAC: 3-[(2R)-3-[4-(2-aminoethyl)piperidin-1-yl]-2-[3-(4,6-dichlorocyclohexa-1,5-dien-1-yl)benzenesulfonamido]-3-oxopropyl]benzene-1-carboximidamide</li> <li>Comment: I-432 is an inhibitor of the serine protease <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=2421" target="_blank" rel="noopener">TMPRSS2</a>.

We have gathered information from various sources, with an aim to cover as many of the pharmacological strategies being considered as we could find. Links are provided to the key ligands and target pages in GtoPdb (where data is available). The page also provides other useful links and resource. We will aim to keep this page updated in this fast changing situation.</p> <h2>Tools</h2> <p>GtoPdb contains a couple of useful tools for searching and visualising pharamcology data &#8211; that combine data from ChEMBL with GtoPdb data. In this release we&#8217;ve update our site to make accessing the visualisation charts easier</p> <p><strong>Ligand Activity Charts</strong></p> <p>This tool provides charts with box plots summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Separate charts are created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.</p> <p>Previously, access to the charts was only found on a ligand&#8217;s summary page, under the biological activity tab. We&#8217;ve now moved that link so it appears more prominently on these pages.<img data-attachment-id="3909" data-permalink="https://blog.guidetopharmacology.org/2020/03/12/database-release-2020-1/ligsumlink/" data-orig-file="https://blog.guidetopharmacology.org/wp-content/uploads/2020/03/ligsumlink.png" data-orig-size="954,425" data-comments-opened="1" data-image-meta="{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}" data-image-title="ligSumLink" data-image-description="" data-image-caption="" data-medium-file="https://blog.guidetopharmacology.org/wp-content/uploads/2020/03/ligsumlink.png?w=300" data-large-file="https://blog.guidetopharmacology.org/wp-content/uploads/2020/03/ligsumlink.png?w=605" loading="lazy" class=" size-full wp-image-3909 aligncenter" style="color:var(--color-text);" src="https://blog.guidetopharmacology.org/wp-content/uploads/2020/03/ligsumlink.png" alt="ligSumLink" width="954" height="425" srcset="https://blog.guidetopharmacology.org/wp-content/uploads/2020/03/ligsumlink.png 954w, https://blog.guidetopharmacology.org/wp-content/uploads/2020/03/ligsumlink.png?w=150&amp;h=67 150w, https://blog.guidetopharmacology.org/wp-content/uploads/2020/03/ligsumlink.png?w=300&amp;h=134 300w, https://blog.guidetopharmacology.org/wp-content/uploads/2020/03/ligsumlink.png?w=768&amp;h=342 768w" sizes="(max-width: 954px) 100vw, 954px"></p> <p>We have also added a new icon on the ligand list pages which indicated whether there are activity charts available for the ligand.

Drugs acting on melatonin receptors are subscribed for circadian disorders (jet lag, shift work, etc.), insomnia and major depression (3). All marketed drugs are non-selective agonists targeting both receptor types so far. Despite large chemical synthesis campaigns over the last 20 years, the pharmacology of melatonin receptors remains poorly explored with few inverse agonistic and signaling pathway-biased compounds and few  selective compounds, in particular for the MT<sub>1</sub> type (2,4). This lack of pharmacological tools goes along with a rather poor diversity in terms of chemical scaffolds currently available (5). Put into this context, a virtual screening looked like a very promising approach to increase the diversity of chemical scaffolds for melatonin receptors, especially now that the crystal structure of the MT<sub>1</sub> receptor has been solved (6). The outcome of the virtual screening study performed by Stein <em>et al.</em> (7) met these high expectations. Overall, 15 new chemical scaffolds were identified from the primary docking of over 150 million virtual molecules (7). Some of the primary hits had pEC<sub>50</sub> values around 1nM, which is remarkable. In terms of functional properties, primary hits and derivatives showed agonistic and inverse agonistic properties with or without selectivity for MT<sub>1</sub> and MT<sub>2</sub>. Two MT<sub>1</sub> selective inverse agonists were further validated in vivo regarding their effects on circadian rhythm parameters in mice under free-running conditions, as well as using an experimental re-entrainment protocol corresponding to an ‘east-bound’ jet lag paradigm.</p> <p>This study is not only of great value for the melatonin receptor field but will also encourage virtual screening approaches on other GPCRs for which high-resolution structures are available. Compared to other GPCR structures, the MT<sub>1</sub> template structure has several limitations as it was in the inactive form despite the presence of the 2‐phenylmelatonin agonist, and it was heavily modified with 9 point mutations and several truncations to facilitate expression and stability (7,8). However, a favorable feature of MT<sub>1</sub> for virtual docking might be its ligand binding pocket which is rather small and hydrophobic with only two key residues important for high-affinity binding. This limits the number of poses to be screened by virtual docking. Moreover, although the screening was designed to identify MT<sub>1</sub> selective compounds, positive hits included also MT<sub>2</sub> selective and non-selective compounds suggesting that virtual screening is currently unable to predict type selective compounds. This might also depend on the quality of the receptor structure and the degree of divergence between receptor types.</p> <p>In conclusion, this article is a nice example of successful virtual screening on GPCRs, one of the desired benefits of crystal structures, that will accelerate the drug development process towards compounds with improved efficacy and target-selectivity.</p> <p>This study investigated two MT<sub>1</sub>-selective inverse agonists, <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=10666" target="_blank" rel="noopener">UCSF7447</a> and <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=10665" target="_blank" rel="noopener">UCSF3384</a>, and a selective MT<sub>2</sub> agonist, <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=10667" target="_blank" rel="noopener">UCSF4226</a>, for their affinities.</p> <p><strong>Comments by Ralf Jockers</strong>, Institut Cochin, CNRS, INSERM, Université de Paris, Paris, France, Chair for NC-IUPHAR Subcommitee for <a href="https://www.guidetopharmacology.org/GRAC/FamilyDisplayForward?familyId=39" target="_blank" rel="noopener">Melatonin receptors</a>.</p> <ol> <li>Dubocovich ML, Delagrange P, Krause DN, Sugden D, Cardinali DP, Olcese J.

Initial research that has focused on direct regulatory mechanisms, such as the activation by the α-subunit of the stimulatory heterotrimeric G-protein Gs (3), and direct phosphorylation of the pore-forming α1- or accessory β2-subunit of the <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=529&amp;familyId=80&amp;familyType=IC">Ca<sub>v</sub>1.2</a> channel has not provided a conclusive answer. β-adrenergic modulation was not (α1 Ser-1928, (4)) or only partially (α1 Ser-1700/Thr-1704, (5)) prevented in mutant mice lacking predicted phosphorylation sites in α1 or β2 subunits (6). This was further supported by an elegant transgenic approach showing that expression of channel complexes with all PKA consensus sites mutated to alanine in the <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=529&amp;familyId=80&amp;familyType=IC">Ca<sub>v</sub>1.2</a> α1 and the β2 subunits (7) has no effects on β-adrenergic modulation.</p> <p>Assuming that other proteins may be involved in this regulatory pathway, Liu et al. (7) used a biotinylation-based proteomic proximity assay to identify proteins in the <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=529&amp;familyId=80&amp;familyType=IC">Ca<sub>v</sub>1.2</a> neighborhood regulated by isoproterenol treatment in cardiomyocytes. This led to the discovery of the small Ras-like G protein Rad as a potential candidate. It belongs to the family of the Rad, Rem, Rem2 and Gem/Kir (RGK) Ras-like GTP-binding proteins, which were shown earlier to inhibit high-voltage-activated Ca<sup>2+</sup> channels by binding to their β-subunits. Indeed, Rad appears to be the long-sought missing piece in the puzzle: in HEK293T Rad-mediated inhibition of cardiac <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=529&amp;familyId=80&amp;familyType=IC">Ca<sub>v</sub>1.2</a> channels was relieved by PKA phosphorylation. Modulation was prevented either by the simultaneous mutation of the known cardiac PKA phosphorylation sites of Rad to alanine or by inhibiting the interaction of Rad with the β-subunit.</p> <p>This mechanism may be universal and may also explain the PKA modulation of other types of β-subunit associated high-voltage activated Ca<sup>2+</sup> channels in Rad expressing cells. It also provides evidence that the mechanism of PKA modulation of <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=529&amp;familyId=80&amp;familyType=IC">Ca<sub>v</sub>1.2</a> Ca<sup>2+</sup> channels appears to differ in different cell types. Clearly, direct phosphorylation of Ser-1928 of the α1-subunit is not required for β-adrenergic regulation of Ca<sub>v</sub>1.2 in the heart (4,7). However, this residue is required for β-adrenergic stimulation of Ca<sup>2+</sup> channels in hippocampal neurons and for hyperglycaemia-induced stimulation of Ca<sup>2+</sup> currents in arterial smooth muscle cells (8,9).</p> <p>Despite compelling evidence for this novel mechanism, several questions remain: First, what is the role of Rad-dependent modulation of the cardiac L-type channel in intact cardiomyocytes, for example in cardiomyocytes expressing Rad with mutated PKA phosphorylation sites. Second, what is the relative importance of Rad versus modulation by direct phosphorylation of Ser-1700 (and Thr-1704), which has also been found to confer some of the PKA activation of L-type current in cardiomyocytes of Ser1700Ala mutant mice (5).</p> <p>Despite these open questions, we are now getting close to understand the molecular mechanisms underlying the fight-or-flight response.</p> <p><strong>Comments by Jörg Striessnig</strong>, University of Innsbruck, Chair for NC-IUPHAR Subcommitee for <a href="https://www.guidetopharmacology.org/GRAC/FamilyDisplayForward?familyId=80">Voltage-gated calcium channels</a>, Liaison for NC-IUPHAR subcommittees on <a href="https://www.guidetopharmacology.org/GRAC/FamilyDisplayForward?familyId=696&amp;familyType=IC">Voltage-gated ion channels</a></p> <ol> <li>Osterrieder W, Brum G, Hescheler J, Trautwein W, Flockerzi V, Hofmann F.

Previously reported also is the structure of the <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=57&amp;familyId=13&amp;familyType=GPCR"> CB<sub>2</sub> cannabinoid receptor</a> with the antagonist <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=10177"> AM10257</a> bound.</p> <p>In the first report (<a href="https://www.cell.com/cell/fulltext/S0092-8674(20)30054-4">1</a>), a non-selective, high potency agonist <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=733">WIN55212-2</a> was bound to a complex of the CB<sub>2</sub> cannabinoid receptor with G<sub>i</sub> to “complete the set” of agonist- and antagonist-bound versions of CB<sub>1</sub> and CB<sub>2</sub> receptors. The authors suggest marked similarities in the binding configuration of the agonist WIN55212-2 and the antagonist AM10257. Based on these structures, two novel ligands were generated; one predicted to be an agonist and the other an antagonist. The functional data supported these predictions, although both novel compounds were markedly less potent than their respective positive controls.</p> <p>In the second report (<a href="https://www.cell.com/cell/fulltext/S0092-8674(20)30055-6">2</a>), agonist-bound versions of both CB<sub>1</sub> and CB<sub>2</sub> cannabinoid receptors complexed with Gi were also described to ‘complete and expand the set’. AM12033 is a novel nitrilodimethylheptyl analogue of <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=2424"> THC</a> with high affinity at both receptors. Structures using this compound were compared to CB<sub>1</sub> receptors bound to the THC-like AM841. The authors suggest similar modes of interaction for agonists at the two receptors, supported by numerous examples of non-selective high potency agonists.</p> <p>Modelling of the second intracellular loop in both reports suggested a structural basis for the CB<sub>2</sub> receptor to couple poorly to Gs. Indeed, a single amino acid variation (L222 in CB<sub>1</sub> and P139 in CB<sub>2</sub> receptors) was highlighted in both studies and evidenced in the previous literature (<a href="https://www.ncbi.nlm.nih.gov/pubmed/23667597">https://www.ncbi.nlm.nih.gov/pubmed/23667597</a>).</p> <p><strong>Comments by Prof. Steve Alexander (<a href="https://twitter.com/mqzspa" target="_blank" rel="noopener">@mqzspa</a>),</strong> <strong>University of Nottingham, UK</strong></p> <p>(1) Xing C. <i>et al.</i> Cryo-EM Structure of the Human Cannabinoid Receptor CB2-G <sub>i</sub> Signaling Complex. <i>Cell</i> (2020) doi:<span class="identifier doi">10.1016/j.cell.2020.01.007 </span>[PMID:<a href="https://www.ncbi.nlm.nih.gov/pubmed/32004460" target="_blank" rel="noopener">32004460</a>]</p> <p>(2) Hua T. <i>et al. </i>Activation and Signaling Mechanism Revealed by Cannabinoid Receptor-G<sub>i</sub> Complex Structures. <i>Cell</i>  (2020) doi:10.1016/j.cell.2020.01.008 [PMID:<a href="https://www.ncbi.nlm.nih.gov/pubmed/32004463" target="_blank" rel="noopener">32004463</a>]</p> <p>&nbsp;</p> </div><!-- end of .post-entry --> <div class="post-data"> Tagged with: <a href="https://blog.guidetopharmacology.org/tag/cannabinoids/" rel="tag">cannabinoids</a>, <a href="https://blog.guidetopharmacology.org/tag/cb1/" rel="tag">CB1</a>, <a href="https://blog.guidetopharmacology.org/tag/cb2/" rel="tag">CB2</a>, <a href="https://blog.guidetopharmacology.org/tag/receptor/" rel="tag">receptor</a>, <a href="https://blog.guidetopharmacology.org/tag/structure/" rel="tag">structure</a><br /> Posted in <a href="https://blog.guidetopharmacology.org/category/hot-topics/" rel="category tag">Hot Topics</a> </div><!-- end of .post-data --> </div><!-- end of #post-3879 --> <div id="post-3870" class="post-3870 post type-post status-publish format-standard hentry category-hot-topics tag-ace2 tag-coronavirus tag-dendritic-cells tag-hcov-229e tag-immunopharmacology tag-pharmacology"> <h1 class="post-title"><a href="https://blog.guidetopharmacology.org/2020/02/03/hot-topics-a-brief-update-on-coronaviruses/" rel="bookmark">Hot Topics: A brief update on&nbsp;coronaviruses</a></h1> <div class="post-meta"> <span class="meta-prep meta-prep-author posted">Posted on </span><a href="https://blog.guidetopharmacology.org/2020/02/03/hot-topics-a-brief-update-on-coronaviruses/" title="2:54 pm" rel="bookmark"><span class="timestamp">February 3, 2020</span></a><span class="byline"> by </span><span class="author vcard"><a class="url fn n" href="https://blog.guidetopharmacology.org/author/guidetopharmacology/" title="View all posts by guidetopharmacology">guidetopharmacology</a></span> <span class="comments-link"> <span class="mdash">&mdash;</span> <a href="https://blog.guidetopharmacology.org/2020/02/03/hot-topics-a-brief-update-on-coronaviruses/#respond">Leave a comment</a> </span> </div><!-- end of .post-meta --> <div class="post-entry"> <p>The new respiratory coronavirus from Wuhan in China is causing intense research activity in the world. Viruses are evidently associated with respiratory infections ranging in severity from the common cold to pneumonia and death. More than 200 viral types have been associated with the common cold, of which 50% of infections are rhinovirus, but also respiratory syncitial virus, influenza – and coronaviruses, particularly human coronavirus-229E (HCoV-229E), which is ‘relatively benign’. Monocytes are relatively resistant to HcoV-229E infection, but rapidly invades, replicates in, and kills dendritic cells within a few hours of infection (Mesel-Lemoine et al., 2012) [1]. Dendritic cells are the sentinel cells in the respiratory tract, and plasmacytoid dendritic cells are a crucial antiviral defence via interferon production. Thus, these viruses can impair control of viral dissemination and the formation of long-lasting immune memory. The cellular receptor for HcoV-229E is CD-13 (<a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=1560" target="_blank" rel="noopener">aminopeptidase-N</a>).<br /> The cellular receptors for coronaviruses are critical for cell entry. Severe acute respiratory syndrome (SARS) coronavirus (SARS-CoV), and HCoV-NL63, bind to <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=1614" target="_blank" rel="noopener">angiotensin converting enzyme2, ACE2</a>, on ciliated cells in the respiratory tract, the crystal structure is known (Song et al., 2018) [2]. The SARS-CoV spike (S) glycoprotein (with S1 and S2 sub-units) on the outer envelope binds to <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=1614" target="_blank" rel="noopener">ACE2</a>, fusing viral and cellular membranes, triggering conformational transformations. Cleavage of the S1/S2 subunits by proteases is critical. Indeed, Simmons et al (2005) [3] showed that SARS-CoV infection involved receptor binding, conformational changes receptor binding and subsequent cathepsin L (and type II transmembrane serine proteases) proteolysis within endosomes – with inhibitors of cathepsin L preventing viral entry. SARS-CoV may lead to markedly elevated cytokine levels, leading to tissue damage, pneumonitis, and acute respiratory distress syndrome (ARDS). The spike proteins in SARS-CoV and Middle East respiratory syndrome coronavirus (MERS-CoV) are crucial for host specificity and jumping between species, e.g. from bats to humans (Lu et al., 2015) [4], and also the recent cross-over to swine acute diarrhoea syndrome coronavirus (SADS-CoV) to pigs (Zhou et al., 2018) [5]. There is intense interest in the complicated ways whereby coronaviruses engage with their target receptors, are activated and replicate. The rapid evolution of coronaviruses is critical as humans have little or no pre-existing immunity SARS- or MERS-CoV.</p> <p>ACE2 has been identified as a potential receptor for the novel coronavirus that was identified as the cause of the respiratory disease outbreak in Wuhan in late 2019 (referred to as 2019 – nCoV by the WHO, or Wuhan coronavirus) [6,7 &amp; 9]. 2019-nCoV is a betacoronavirus, and, in common with the SARS-CoV [8], the viral spike protein is postulated to engage ACE2 for viral entry [7]. The data presented by Letko and Munzter [7] is preliminary and has not been peer-reviewed, but a rapid pace of research is needed in the present circumstances. For example, in another recent, preliminary report, ACE2 receptor expression is highly expressed in type II alveolar cells (AT2) with much individual variation and the authors reported that the cells also expressed many genes involved in viral reproduction and transmission [10]. While these findings are preliminary, the rapid publications in bioRxiv and similar archives are crucial in what is now officially a global health emergency.

This nicely adds to recent publications reporting of the high-resolution structures of L-type Ca<sup>2+</sup> channel blockers (<a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=2514">nifedipine</a>, <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=2523">nimodipine</a>, <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=6981">amlodipine</a>, <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=2406">verapamil</a>, <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=2298">diltiazem</a>) bound to the rabbit <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=528&amp;familyId=80&amp;familyType=IC">Cav1.1</a> skeletal muscle Ca<sup>2+</sup> channel (2) and to the model Ca<sup>2+</sup> channel CavAb (Ca<sup>2+</sup>-selectivity engineered into the bacterial homotetrameric Na<sup>+</sup>-channel NavAb; 3, 4).</p> <p>Together these three publications provide important insight into how small molecule channel blockers interact with their high affinity binding domains within Ca<sup>2+</sup> channels. They also reveal a remarkable similarity between the core structures (i.e. the voltage-sensors and the pore domains) between not only the closely related <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=528&amp;familyId=80&amp;familyType=IC">Cav1.1</a> and <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=535&amp;familyId=80&amp;familyType=IC">Cav3.1</a> channels but also their bacterial ancestor CavAb.</p> <p>Moreover, although some differences exist, the binding poses of L-type Ca<sup>2+</sup> channel blockers in the mammalian <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=528&amp;familyId=80&amp;familyType=IC">Cav1.1</a> and the bacterial CavAb channel are very similar. In both structures <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=2406">verapamil</a> and <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=2298">diltiazem</a> bind within the central cavity, compatible with their pore-blocking properties predicted in functional studies. In contrast, dihydropyridines like <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=2523">nimodipine</a> and <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=2514">nifedipine</a> bind within a fenestration created by adjacent transmembrane S6 helices (IIIS6 and IVS6). These fenestrations penetrate the sides of the central cavities in both voltage gated Na<sup>+</sup>&#8211; and Ca<sup>2+</sup> channels and connect them to the surrounding lipid bilayer of the plasma membrane (5). In accordance with functional studies, these dihydropyridines must therefore inhibit L-type channels by allosterically interfering with gating rather than pore block.</p> <p>These findings raise the important question about how <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=7718">Z944</a> can selectively inhibit T-type Ca<sup>2+</sup> channels. This drug is currently in clinical development for the treatment of epilepsy and neuropathic pain. It appears that <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=7718">Z944</a> bound to <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=535&amp;familyId=80&amp;familyType=IC">Cav3.1</a> combines the binding modes of both pore blockers and allosteric blockers. Its phenyl ring projects into the fenestration between repeats II and III (similar to <a href="https://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=2514">nifedipine</a> binding), whereas the other end of the molecule projects down through the central cavity to the intracellular mouth of the pore. A prominent interaction was found with lysine-1462, a residue unique for T-type channels. Its mutation to L-type residues reduced drug sensitivity in functional studies suggesting that it is one of the determinants for T-type selectivity.</p> <p>Taken together the accumulating structural insight into drug binding and modulation will greatly facilitate structure-guided drug discovery. This may lead to new oral subtype-selective blockers of voltage-gated Ca<sup>2+</sup> channels with therapeutic potential for the treatment of epilepsy (T-type), pain (T-type, N-type), tremor (T-type), primary aldosteronism (<a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=530&amp;familyId=80&amp;familyType=IC">Cav1.3</a> L-type), progression of Parkinsons disease (<a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=530&amp;familyId=80&amp;familyType=IC">Cav1.3</a>, R-type) or rare neurodevelopmental disorders (<a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=530&amp;familyId=80&amp;familyType=IC">Cav1.3</a> L-type) (6,7).</p> <p><strong>Comments by Jörg Striessnig</strong>, University of Innsbruck, Chair for NC-IUPHAR Subcommitee for <a href="https://www.guidetopharmacology.org/GRAC/FamilyDisplayForward?familyId=80">Voltage-gated calcium channels</a>, Liaison for NC-IUPHAR subcommittees on <a href="https://www.guidetopharmacology.org/GRAC/FamilyDisplayForward?familyId=696&amp;familyType=IC">Voltage-gated ion channels</a></p> <ol> <li>Zhao, Y., Huang, G., Wu, Q., Wu, K., Li, R., Lei, J., Pan, X., and Yan, N.

Following the recent description of the <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=269&amp;familyId=35&amp;familyType=GPCR" target="_blank" rel="noopener">CysLT1 receptor</a> structure, Gusach <em>et al</em>. now describe the crystal structures of the <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=270&amp;familyId=35&amp;familyType=GPCR" target="_blank" rel="noopener">CysLT2 receptor</a> in complex with dual CysLT1/CysLT2 receptor antagonists (1). This is an important advancement, since it allows to reveal specific characteristics of the two CysLT receptors in terms of ligand recognition and subtype selectivity. In this context, differences in the intracellular helix 8 emerge as particular subtype determinants, which may affect G-protein regulation and β-arrestin binding. The study by Gusach <em>et al.</em> (1) further provides structural insights into the changes in ligand binding and downstream signaling by CysLT2R disease-related single nucleotide polymorphisms (SNP) associated with asthma and cancer. The deciphering of the crystal structures for the CysLT1 and CysLT2 receptors will open up for the design of CysLT receptor antagonists with improved affinity/efficacy or subtype selectivity profiles. The insights into the CysLT receptor genome-structure-function relations may facilitate the prediction of disease associations and potentially further expanding the therapeutic indications of CysLT receptor antagonists.</p> <p><strong>Comments by </strong><strong>Magnus Bäck, MD PhD, (</strong><a href="https://twitter.com/TransCardio" target="_blank" rel="noopener">@TransCardio</a><strong>), </strong>Karolinska Institutet and University Hospital, Stockholm, Sweden; Chairman NC-IUPHAR subcommittee on Leukotriene Receptors</p> <p>(1) Gusach, A., Luginina, A., Marin, E. <i>et al.</i> Structural basis of ligand selectivity and disease mutations in cysteinyl leukotriene receptors. <i>Nat Commun</i> <b>10, </b>5573 (2019) doi:10.1038/s41467-019-13348-2 [PMID:<a href="https://www.ncbi.nlm.nih.gov/pubmed/31811124" target="_blank" rel="noopener">31811124</a>]</p> </div><!-- end of .post-entry --> <div class="post-data"> Tagged with: <a href="https://blog.guidetopharmacology.org/tag/gpcrs/" rel="tag">GPCRs</a>, <a href="https://blog.guidetopharmacology.org/tag/hot-topic/" rel="tag">hot topic</a>, <a href="https://blog.guidetopharmacology.org/tag/pharmacology/" rel="tag">pharmacology</a>, <a href="https://blog.guidetopharmacology.org/tag/protein-structure/" rel="tag">protein structure</a><br /> Posted in <a href="https://blog.guidetopharmacology.org/category/hot-topics/" rel="category tag">Hot Topics</a> </div><!-- end of .post-data --> </div><!-- end of #post-3853 --> <div id="post-3848" class="post-3848 post type-post status-publish format-standard hentry category-hot-topics tag-gpcrs tag-hot-topic tag-protein-structure"> <h1 class="post-title"><a href="https://blog.guidetopharmacology.org/2019/11/28/hot-topics-new-crystal-structure-of-the-muscarinic-m5-receptor-completes-the-set/" rel="bookmark">Hot Topics: New crystal structure of the muscarinic M5 receptor completes the&nbsp;set</a></h1> <div class="post-meta"> <span class="meta-prep meta-prep-author posted">Posted on </span><a href="https://blog.guidetopharmacology.org/2019/11/28/hot-topics-new-crystal-structure-of-the-muscarinic-m5-receptor-completes-the-set/" title="10:32 am" rel="bookmark"><span class="timestamp">November 28, 2019</span></a><span class="byline"> by </span><span class="author vcard"><a class="url fn n" href="https://blog.guidetopharmacology.org/author/guidetopharmacology/" title="View all posts by guidetopharmacology">guidetopharmacology</a></span> <span class="comments-link"> <span class="mdash">&mdash;</span> <a href="https://blog.guidetopharmacology.org/2019/11/28/hot-topics-new-crystal-structure-of-the-muscarinic-m5-receptor-completes-the-set/#respond">Leave a comment</a> </span> </div><!-- end of .post-meta --> <div class="post-entry"> <p><a href="https://www.guidetopharmacology.org/GRAC/FamilyDisplayForward?familyId=2">Muscarinic receptors</a> consist of 5 G protein-coupled receptors which along with nicotinic ion channels mediate the effects of acetylcholine. Despite years of research on the role of muscarinic receptors in the brain and periphery the <a href="https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=17&amp;familyId=2&amp;familyType=GPCR">Muscarinic M5</a> receptor has stood out in contrast to M1 -M4 as one which we know little about. The M5 receptor has a unique and unusual distribution in the brain being enriched in mid brain dopamine neurons and in the cerebellum. A lack of selective chemical tools has hampered our ability to study the function of the receptor. Now Vuckovic et al. [1] have solved the X-ray crystal structure of the M5 receptor in complex with the non-selective antagonist tiotropium in the presence of a conformational stabilizing mutation. Since tiotropium was also used to solve the structure of several other muscarinic receptors a direct comparison can be made across the subtypes which will enable the design of selective tool compounds. Significant progress has been made in utilizing crystal structures to design selective orthosteric and allosteric ligands at this family of receptors. This final structure completes the set of muscarinic receptor structures solved and hopefully will pave the way to further understanding of the biology of M5 and its role in disorders such as drug addiction and depression.</p> <p><strong>Comments by Fiona H.
