This approach is used for the treatment of many chronic and infectious diseases. Potentiating agents are currently explored in combination therapy, resulting in excellent therapeutic outcomes. Breast cancer and malaria are two chronic conditions responsible globally for high death rates. In this research, a class of polymer-drug conjugates containing potentiating agents with either antimalarial or anticancer drugs were prepared by Michael Addition Polymerization reaction and ring-opening polymerization reaction. Conjugation of potentiating agents with bioactive compounds into the polymers resulted in conjugates with good water solubility, highly selective and non-toxic. In vitro cytotoxicity and in vitro antiplasmodial evaluation on the conjugates revealed that the conjugates were more effective when compared to the free drugs. The drug release studies further showed that the release profile of the drugs from the conjugates was sustained. The findings revealed the potential of polymer-drug conjugates to overcome drug toxicity and drug resistance, which is common with the currently used antimalarial and anticancer drugs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anticancer" title="anticancer">anticancer</a>, <a href="https://publications.waset.org/abstracts/search?q=antimalarials" title=" antimalarials"> antimalarials</a>, <a href="https://publications.waset.org/abstracts/search?q=combination%20therapy" title=" combination therapy"> combination therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer-drug%20conjugates" title=" polymer-drug conjugates"> polymer-drug conjugates</a> </p> <a href="https://publications.waset.org/abstracts/111039/development-and-in-vitro-evaluation-of-polymer-drug-conjugates-containing-potentiating-agents-for-combination-therapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111039.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">133</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2210</span> Development of Self Emulsifying Drug Delivery Systems (SEDDS) of Anticancer Agents Used in AYUSH System of Medicine for Improved Oral Bioavailability Followed by Their Pharmacological Evaluation Using Biotechnological Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meenu%20Mehta">Meenu Mehta</a>, <a href="https://publications.waset.org/abstracts/search?q=Munish%20Garg"> Munish Garg</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of oral anticancer drugs from AYUSH system of medicine is widely increased among the society due to their low cost, enhanced efficacy, increased patient preference, lack of inconveniences related to infusion and they provide an opportunity to develop chronic treatment regimens. However, oral delivery of these drugs usually laid down by the limited bioavailability of the drug, which is associated with a wide variation. As most of the cytotoxic agents have a narrow therapeutic window and are dosed at or near the maximum tolerated dose, a wide variability in the bioavailability can negatively affect treatment result. It is estimated that 40% of active substances are poorly soluble in water. The improvement of bio-availability of drugs with such properties presents one of the greatest challenges in drug formulations. There are several techniques reported in literature. Among all these Self Emulsifying Drug Delivery System (SEDDS) has gained more attention due to enhanced oral bio-availability enabling a reduction in dose. Thus, SEDDS anticancer drugs will have the increased bioavailability and efficacy. These dosage form will provide societal benefit in a cost-effective manner as compared to other oral dosage forms. Present study reflects on the formulation strategies as SEDDS for oral anticancer agents of AYUSH system for enhanced bioavailability with proven efficacy by cancer cell lines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anticancer%20agents" title="anticancer agents">anticancer agents</a>, <a href="https://publications.waset.org/abstracts/search?q=AYUSH%20system" title=" AYUSH system"> AYUSH system</a>, <a href="https://publications.waset.org/abstracts/search?q=bioavailability" title=" bioavailability"> bioavailability</a>, <a href="https://publications.waset.org/abstracts/search?q=SEDDS" title=" SEDDS"> SEDDS</a> </p> <a href="https://publications.waset.org/abstracts/58981/development-of-self-emulsifying-drug-delivery-systems-sedds-of-anticancer-agents-used-in-ayush-system-of-medicine-for-improved-oral-bioavailability-followed-by-their-pharmacological-evaluation-using-biotechnological-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58981.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">306</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2209</span> Synthesis and Molecular Docking Studies of Hydrazone Derivatives Potent Inhibitors as a Human Carbonic Anhydrase IX</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sema%20%C5%9Eeno%C4%9Flu">Sema Şenoğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Sevgi%20Karaku%C5%9F"> Sevgi Karakuş</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hydrazone scaffold is important to design new drug groups and is found to possess numerous uses in pharmaceutical chemistry. Besides, hydrazone derivatives are also known for biological activities such as anticancer, antimicrobial, antiviral, and antifungal. Hydrazone derivatives are promising anticancer agents because they inhibit cancer proliferation and induce apoptosis. Human carbonic anhydrase IX has a high potential to be an antiproliferative drug target, and targeting this protein is also important for obtaining potential anticancer inhibitors. The protein construct was retrieved as a PDB file from the RCSB protein database. This binding interaction of proteins and ligands was performed using Discovery Studio Visualizer. In vitro inhibitory activity of hydrazone derivatives was tested against enzyme carbonic anhydrase IX on the PyRx programme. Most of these molecules showed remarkable human carbonic anhydrase IX inhibitory activity compared to the acetazolamide. As a result, these compounds appear to be a potential target in drug design against human carbonic anhydrase IX. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer" title="cancer">cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=carbonic%20anhydrase%20IX%20enzyme" title=" carbonic anhydrase IX enzyme"> carbonic anhydrase IX enzyme</a>, <a href="https://publications.waset.org/abstracts/search?q=docking" title=" docking"> docking</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrazone" title=" hydrazone"> hydrazone</a> </p> <a href="https://publications.waset.org/abstracts/171356/synthesis-and-molecular-docking-studies-of-hydrazone-derivatives-potent-inhibitors-as-a-human-carbonic-anhydrase-ix" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171356.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2208</span> Design, Synthesis and Pharmacological Investigation of Novel 2-Phenazinamine Derivatives as a Mutant BCR-ABL (T315I) Inhibitor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gajanan%20M.%20Sonwane">Gajanan M. Sonwane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, the entire pharmaceutical industry is facing the challenge of increasing efficiency and innovation. The major hurdles are the growing cost of research and development and a concurrent stagnating number of new chemical entities (NCEs). Hence, the challenge is to select the most druggable targets and to search the equivalent drug-like compounds, which also possess specific pharmacokinetic and toxicological properties that allow them to be developed as drugs. The present research work includes the studies of developing new anticancer heterocycles by using molecular modeling techniques. The heterocycles synthesized through such methodology are much effective as various physicochemical parameters have been already studied and the structure has been optimized for its best fit in the receptor. Hence, on the basis of the literature survey and considering the need to develop newer anticancer agents, new phenazinamine derivatives were designed by subjecting the nucleus to molecular modeling, viz., GQSAR analysis and docking studies. Simultaneously, these designed derivatives were subjected to in silico prediction of biological activity through PASS studies and then in silico toxicity risk assessment studies. In PASS studies, it was found that all the derivatives exhibited a good spectrum of biological activities confirming its anticancer potential. The toxicity risk assessment studies revealed that all the derivatives obey Lipinski’s rule. Amongst these series, compounds 4c, 5b and 6c were found to possess logP and drug-likeness values comparable with the standard Imatinib (used for anticancer activity studies) and also with the standard drug methotrexate (used for antimitotic activity studies). One of the most notable mutations is the threonine to isoleucine mutation at codon 315 (T315I), which is known to be resistant to all currently available TKI. Enzyme assay planned for confirmation of target selective activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drug%20design" title="drug design">drug design</a>, <a href="https://publications.waset.org/abstracts/search?q=tyrosine%20kinases" title=" tyrosine kinases"> tyrosine kinases</a>, <a href="https://publications.waset.org/abstracts/search?q=anticancer" title=" anticancer"> anticancer</a>, <a href="https://publications.waset.org/abstracts/search?q=Phenazinamine" title=" Phenazinamine"> Phenazinamine</a> </p> <a href="https://publications.waset.org/abstracts/148609/design-synthesis-and-pharmacological-investigation-of-novel-2-phenazinamine-derivatives-as-a-mutant-bcr-abl-t315i-inhibitor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148609.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">116</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2207</span> Curcumin Loaded Modified Chitosan Nanocarrier for Tumor Specificity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20T.%20Kumbhar">S.

The encapsulation efficiency was more than 80%, with improved drug loading capacity. The in-vitro drug release study showed that curcumin release rate was decreased significantly.

Batch adsorption experiments were carried out for adsorption of 5-Fluorouracil (5-FL) using MCNTs. The effect of various operating variables, viz., adsorbent dosage, pH, contact time and temperature for adsorption of 5-Fluorouracil (5-FL) has been studied. The Freundlich adsorption model was successfully employed to describe the adsorption process. It was found that the pseudo-second-order mechanism is predominant and the overall rate of the 5-Fluorouracil (5-FL) adsorption process appears to be controlled by the more than one-step. Thermodynamic parameters such as free energy change (ΔG°), enthalpy change (ΔH°) and entropy change (ΔS°) have been calculated respectively, revealed the spontaneous, endothermic and feasible nature of adsorption process. The results showed that carbon nano tubes were able to form supra molecular complexes with 5-Fluorouracil (5-FL) by π-π stacking and possessed favorable loading properties as drug carriers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drug" title="drug">drug</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=anticancer" title=" anticancer"> anticancer</a>, <a href="https://publications.waset.org/abstracts/search?q=5-Fluorouracil%20%285-FL%29" title=" 5-Fluorouracil (5-FL) "> 5-Fluorouracil (5-FL) </a> </p> <a href="https://publications.waset.org/abstracts/22284/kinetic-and-thermodynamics-of-sorption-of-5-fluorouracil-5-fl-on-carbon-nanotubes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22284.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">361</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2205</span> Binding Studies of Complexes of Anticancer Drugs with DNA and Enzymes Involved in DNA Replication Using Molecular Docking and Cell Culture Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fouzia%20Perveen">Fouzia Perveen</a>, <a href="https://publications.waset.org/abstracts/search?q=Rumana%20Qureshi"> Rumana Qureshi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The presently studied twelve anticancer drugs are the cytotoxic agents which inhibit the replication of DNA and activity of enzymes involved in DNA replication namely topoisomerase-II, polymerase and helicase and have shown remarkable anticancer activity in clinical trials. In this study, we performed molecular docking studies of twelve antitumor drugs against DNA and DNA enzymes in the presence and absence of ascorbic acid (AA) and developed the quantitative structure-activity relationship (QSAR) model for anticancer activity screening. A number of electronic and steric descriptors were calculated using MOE software package. QSAR was established showing a correlation of binding strength with various physicochemical descriptors. Out of these twelve, eight cytotoxic drugs were tested on Non-Small Cell Lung Cancer cell lines (H-157 and H-1299) in the absence and presence of ascorbic acid and experimental IC50 values were calculated. From the docking studies, binding constants were calculated indicating the strength of drug-DNA and drug-enzyme complex formation and it was correlated to the IC50 values (both experimental and theoretical). These results can offer useful references for directing the molecular design of DNA enzyme inhibitor with improved anticancer activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ascorbic%20acid" title="ascorbic acid">ascorbic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=binding%20constant" title=" binding constant"> binding constant</a>, <a href="https://publications.waset.org/abstracts/search?q=cytotoxic%20agents" title=" cytotoxic agents"> cytotoxic agents</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20culture" title=" cell culture"> cell culture</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA" title=" DNA"> DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20enzymes" title=" DNA enzymes"> DNA enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20docking" title=" molecular docking"> molecular docking</a> </p> <a href="https://publications.waset.org/abstracts/23535/binding-studies-of-complexes-of-anticancer-drugs-with-dna-and-enzymes-involved-in-dna-replication-using-molecular-docking-and-cell-culture-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23535.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">427</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2204</span> The Rational Design of Original Anticancer Agents Using Computational Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Majid%20Farsadrooh">Majid Farsadrooh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehran%20Feizi-Dehnayebi"> Mehran Feizi-Dehnayebi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Serum albumin is the most abundant protein that is present in the circulatory system of a wide variety of organisms. Although it is a significant macromolecule, it can contribute to osmotic blood pressure and also, plays a superior role in drug disposition and efficiency. Molecular docking simulation can improve in silico drug design and discovery procedures to propound a lead compound and develop it from the discovery step to the clinic. In this study, the molecular docking simulation was applied to select a lead molecule through an investigation of the interaction of the two anticancer drugs (Alitretinoin and Abemaciclib) with Human Serum Albumin (HSA). Then, a series of new compounds (a-e) were suggested using lead molecule modification. Density functional theory (DFT) including MEP map and HOMO-LUMO analysis were used for the newly proposed compounds to predict the reactivity zones on the molecules, stability, and chemical reactivity. DFT calculation illustrated that these new compounds were stable. The estimated binding free energy (ΔG) values for a-e compounds were obtained as -5.78, -5.81, -5.95, -5,98, and -6.11 kcal/mol, respectively. Finally, the pharmaceutical properties and toxicity of these new compounds were estimated through OSIRIS DataWarrior software. The results indicated no risk of tumorigenic, irritant, or reproductive effects and mutagenicity for compounds d and e. As a result, compounds d and e, could be selected for further study as potential therapeutic candidates.

Intratumoral injection of chemotherapeutic agents is a potentially more effective alternative to systemic administration because direct delivery of the anticancer drug to the target may improve both the stability and efficacy of anticancer drugs. Injectable in situ-forming gels have attracted considerable attention because they can achieve site specific drug delivery, long term action periods, and improved patient compliance. Objective: Objective of present study is to confirm clinical benefit of intratumoral chemotherapy using injectable in situ-forming poly(ethylene glycol)-b-polycaprolactone diblock copolymer (MP) and Dox with increase in efficacy and reducing the toxicity in patients with cancer diseases. Methods and methodology: We prepared biodegradable MP hydrogel and measured viscosity for the evaluation of thermo-sensitive property. In vivo antitumor activity was performed with normal saline, MP only, single free Dox, repeat free Dox, and Dox-loaded MP gel. The remaining amount of Dox drug was measured using HPLC after the mouse was sacrified. For cytotoxicity studies WST-1 assay was performed. Histological analysis was done with H&E and TUNEL processes respectively. Results: The works in this experiment showed that Dox-loaded MP have biodegradable drug depot property. Dox-loaded MP gels showed remarkable in vitro cytotoxicity activities against cancer cells. Finally, this work indicates that injection of Dox-loaded MP allowed Dox to act effectively in the tumor and induced long-lasting supression of tumor growth. Conclusion: This work has examined the potential clinical utility of intratumorally injected Dox-loaded MP gel, which shows significant effect of higher local Dox retention compared with systemically administered Dox. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=injectable%20in-situ%20forming%20hydrogel" title="injectable in-situ forming hydrogel">injectable in-situ forming hydrogel</a>, <a href="https://publications.waset.org/abstracts/search?q=anticancer" title=" anticancer"> anticancer</a>, <a href="https://publications.waset.org/abstracts/search?q=doxorubicin" title=" doxorubicin"> doxorubicin</a>, <a href="https://publications.waset.org/abstracts/search?q=intratumoral%20injection" title=" intratumoral injection"> intratumoral injection</a> </p> <a href="https://publications.waset.org/abstracts/9290/anticancer-effect-of-doxorubicin-using-injectable-hydrogel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9290.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">408</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2202</span> Biodegradable Polymeric Vesicles Containing Magnetic Nanoparticles, Quantum Dots and Anticancer Drugs for Drug Delivery and Imaging</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fei%20Ye">Fei Ye</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%85sa%20Barrefelt"> Åsa Barrefelt</a>, <a href="https://publications.waset.org/abstracts/search?q=Manuchehr%20Abedi-Valugerdi"> Manuchehr Abedi-Valugerdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalid%20M.%20Abu-Salah"> Khalid M.

Furthermore, targeted drug delivery can be developed to improve chemotherapy in cancer treatment, not only by enhancing intracellular uptake by target cells but also by reducing the adverse effects in non-target organs. Inorganic imaging agents, delivered together with anti-cancer drugs, enhance the local imaging contrast and provide precise diagnosis as well as evaluation of therapy efficacy. We have developed biodegradable polymeric vesicles as a nanocarrier system for multimodal bio-imaging and anticancer drug delivery. The poly (lactic-co-glycolic acid) PLGA) vesicles were fabricated by encapsulating inorganic imaging agents of superparamagnetic iron oxide nanoparticles (SPION), manganese-doped zinc sulfide (MN:ZnS) quantum dots (QDs) and the anticancer drug busulfan into PLGA nanoparticles via an emulsion-evaporation method. T2-weighted magnetic resonance imaging (MRI) of PLGA-SPION-Mn:ZnS phantoms exhibited enhanced negative contrast with r2 relaxivity of approximately 523 s-1 mM-1 Fe. Murine macrophage (J774A) cellular uptake of PLGA vesicles started fluorescence imaging at 2 h and reached maximum intensity at 24 h incubation. The drug delivery ability PLGA vesicles was demonstrated in vitro by release of busulfan. PLGA vesicles degradation was studied in vitro, showing that approximately 32% was degraded into lactic and glycolic acid over a period of 5 weeks. The biodistribution of PLGA vesicles was investigated in vivo by MRI in a rat model. Change of contrast in the liver could be visualized by MRI after 7 min and maximal signal loss detected after 4 h post-injection of PLGA vesicles. Histological studies showed that the presence of PLGA vesicles in organs was shifted from the lungs to the liver and spleen over time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodegradable%20polymers" title="biodegradable polymers">biodegradable polymers</a>, <a href="https://publications.waset.org/abstracts/search?q=multifunctional%20nanoparticles" title=" multifunctional nanoparticles"> multifunctional nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20dots" title=" quantum dots"> quantum dots</a>, <a href="https://publications.waset.org/abstracts/search?q=anticancer%20drugs" title=" anticancer drugs"> anticancer drugs</a> </p> <a href="https://publications.waset.org/abstracts/29159/biodegradable-polymeric-vesicles-containing-magnetic-nanoparticles-quantum-dots-and-anticancer-drugs-for-drug-delivery-and-imaging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29159.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">472</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2201</span> Synergistic Effect of Doxorubicin-Loaded Silver Nanoparticles – Polymeric Conjugates on Breast Cancer Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nancy%20M.%20El-Baz">Nancy M.

Despite the effectiveness of chemotherapeutic agents, their systemic toxicity and non-selective anticancer actions represent the main obstacles facing cancer curability. Due to the effective enhanced permeability and retention (EPR) effect of nanomaterials, nanoparticles (NPs) have been used as drug nanocarriers providing targeted cancer drug delivery systems. In addition, several inorganic nanoparticles such as silver (AgNPs) nanoparticles demonstrated a potent anticancer activity against different cancers. The present study aimed at formulating core-shell inorganic NPs-based combinatorial therapy based on combining the anticancer activity of AgNPs along with doxorubicin (DOX) and evaluating their cytotoxicity on MCF-7 breast cancer cells. These inorganic NPs-based combinatorial therapies were designed to (i) Target and kill cancer cells with high selectivity, (ii) Have an improved efficacy/toxicity balance, and (iii) Have an enhanced therapeutic index when compared to the original non-modified DOX with much lower dosage The in-vitro cytotoxicity studies demonstrated that the NPs-based combinatorial therapy achieved the same efficacy of non-modified DOX on breast cancer cell line, but with 96% reduced dose. Such reduction in DOX dose revealed that the combination between DOX and NPs possess a synergic anticancer activity against breast cancer. We believe that this is the first report on a synergic anticancer effect at very low dose of DOX against MCF-7 cells. Future studies on NPs-based combinatorial therapy may aid in formulating novel and significantly more effective cancer therapeutics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanoparticles-based%20combinatorial%20therapy" title="nanoparticles-based combinatorial therapy">nanoparticles-based combinatorial therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanoparticles" title=" silver nanoparticles"> silver nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=doxorubicin" title=" doxorubicin"> doxorubicin</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title=" breast cancer"> breast cancer</a> </p> <a href="https://publications.waset.org/abstracts/25247/synergistic-effect-of-doxorubicin-loaded-silver-nanoparticles-polymeric-conjugates-on-breast-cancer-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25247.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">436</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2200</span> Synthesis, Characterization and Bioactivity of Methotrexate Conjugated Fluorescent Carbon Nanoparticles in vitro Model System Using Human Lung Carcinoma Cell Lines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Matin">Abdul Matin</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ajmal"> Muhammad Ajmal</a>, <a href="https://publications.waset.org/abstracts/search?q=Uzma%20Yunus"> Uzma Yunus</a>, <a href="https://publications.waset.org/abstracts/search?q=Noaman-ul%20Haq"> Noaman-ul Haq</a>, <a href="https://publications.waset.org/abstracts/search?q=Hafiz%20M.%20Shohaib"> Hafiz M.

Here, highly fluorescent, monodispersed and water-soluble CNPs were synthesized directly from a suitable carbohydrate source (glucose and sucrose) by one-step acid assisted ultrasonic treatment at 35 KHz for 4 hours. This method is green, simple, rapid and economical and can be used for large scale production and applications. The average particle sizes of CNPs are less than 10nm and they emit bright and colorful green-blue fluorescence under the irradiation of UV-light at 365nm. The CNPs were characterized by scanning electron microscopy, fluorescent spectrophotometry, Fourier transform infrared spectrophotometry, ultraviolet-visible spectrophotometry and TGA analysis. Fluorescent CNPs were used as fluorescent probe and nano-carriers for anticancer drug. Functionalized CNPs (with ethylene diamine) were attached with anticancer drug-Methotrexate. In vitro bioactivity and biocompatibility of CNPs-drug conjugates was evaluated by LDH assay and Sulforhodamine B assay using human lung carcinoma cell lines (H157). Our results reveled that CNPs showed biocompatibility and CNPs-anticancer drug conjugates have shown potent cytotoxic effects and high antitumor activities in lung cancer cell lines. CNPs are proved to be excellent substitute for conventional drug delivery cargo systems and anticancer therapeutics in vitro. Our future studies will be more focused on using the same nanoparticles in vivo model system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanoparticles" title="carbon nanoparticles">carbon nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanoparticles-methotrexate%20conjugates" title=" carbon nanoparticles-methotrexate conjugates"> carbon nanoparticles-methotrexate conjugates</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20lung%20carcinoma%20cell%20lines" title=" human lung carcinoma cell lines"> human lung carcinoma cell lines</a>, <a href="https://publications.waset.org/abstracts/search?q=lactate%20dehydrogenase" title=" lactate dehydrogenase"> lactate dehydrogenase</a>, <a href="https://publications.waset.org/abstracts/search?q=methotrexate" title=" methotrexate"> methotrexate</a> </p> <a href="https://publications.waset.org/abstracts/42526/synthesis-characterization-and-bioactivity-of-methotrexate-conjugated-fluorescent-carbon-nanoparticles-in-vitro-model-system-using-human-lung-carcinoma-cell-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42526.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">305</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2199</span> Floating Oral in Situ Gelling System of Anticancer Drug</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Umme%20Hani">Umme Hani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Rahmatulla"> Mohammed Rahmatulla</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Ghazwani"> Mohammed Ghazwani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Alqahtani"> Ali Alqahtani</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahya%20Alhamhoom"> Yahya Alhamhoom</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and introduction: Neratinib is a potent anticancer drug used for the treatment of breast cancer. It is poorly soluble at higher pH, which tends to minimize the therapeutic effects in the lower gastrointestinal tract (GIT) leading to poor bioavailability. An attempt has been made to prepare and develop a gastro-retentive system of Neratinib to improve the drug bioavailability in the GIT by enhancing the gastric retention time. Materials and methods: In the present study a three-factor at two-level (23) factorial design based optimization was used to inspect the effects of three independent variables (factors) such as sodium alginate (A), sodium bicarbonate (B) and sodium citrate (C) on the dependent variables like in vitro gelation, in vitro floating, water uptake and percentage drug release. Results: All the formulations showed pH in the range 6.7 ±0.25 to 7.4 ±0.24, percentage drug content was observed to be 96.3±0.27 to 99.5 ±0.28%, in vitro gelation observed as gelation immediate remains for an extended period. Percentage of water uptake was in the range between 9.01±0.15 to 31.01±0.25%, floating lag time was estimated form 7±0.39 to 57±0.36 sec. F4 and F5 showed floating even after 12hrs. All formulations showed a release of around 90% drug release within 12hr. It was observed that the selected independent variables affect the dependent variables. Conclusion: The developed system may be a promising and alternative approach to augment gastric retention of drugs and enhances the therapeutic efficacy of the drug. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neratinib" title="neratinib">neratinib</a>, <a href="https://publications.waset.org/abstracts/search?q=2%C2%B3%20factorial%20design" title=" 2³ factorial design"> 2³ factorial design</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20alginate" title=" sodium alginate"> sodium alginate</a>, <a href="https://publications.waset.org/abstracts/search?q=floating" title=" floating"> floating</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20situ%20gelling%20system" title=" in situ gelling system"> in situ gelling system</a> </p> <a href="https://publications.waset.org/abstracts/116325/floating-oral-in-situ-gelling-system-of-anticancer-drug" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116325.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">163</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2198</span> Preparation of Polymer-Stabilized Magnetic Iron Oxide as Selective Drug Nanocarriers to Human Acute Myeloid Leukemia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kheireddine%20El-Boubbou">Kheireddine El-Boubbou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Drug delivery to target human acute myeloid leukemia (AML) using a nanoparticulate chemotherapeutic formulation that can deliver drugs selectively to AML cancer is hugely needed. In this work, we report the development of a nanoformulation made of polymeric-stabilized multifunctional magnetic iron oxide nanoparticles (PMNP) loaded with the anticancer drug Doxorubicin (Dox) as a promising drug carrier to treat AML. Dox@PMNP conjugates simultaneously exhibited high drug content, maximized fluorescence, and excellent release properties. Nanoparticulate uptake and cell death following addition of Dox@PMNPs were then evaluated in different types of human AML target cells, as well as on normal human cells. While the unloaded MNPs were not toxic to any of the cells, Dox@PMNPs were found to be highly toxic to the different AML cell lines, albeit at different inhibitory concentrations (IC<sub>50</sub> values), but showed very little toxicity towards the normal cells. In comparison, free Dox showed significant potency concurrently to all the cell lines, suggesting huge potentials for the use of Dox@PMNPs as selective AML anticancer cargos. Live confocal imaging, fluorescence and electron microscopy confirmed that Dox is indeed delivered to the nucleus in relatively short periods of time, causing apoptotic cell death. Importantly, this targeted payload may potentially enhance the effectiveness of the drug in AML patients and may further allow physicians to image leukemic cells exposed to Dox@PMNPs using MRI. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetic%20nanoparticles" title="magnetic nanoparticles">magnetic nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20delivery" title=" drug delivery"> drug delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=acute%20myeloid%20leukemia" title=" acute myeloid leukemia"> acute myeloid leukemia</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20oxide" title=" iron oxide"> iron oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20nanotherapy" title=" cancer nanotherapy"> cancer nanotherapy</a> </p> <a href="https://publications.waset.org/abstracts/65856/preparation-of-polymer-stabilized-magnetic-iron-oxide-as-selective-drug-nanocarriers-to-human-acute-myeloid-leukemia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65856.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">229</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2197</span> Application of Computational Chemistry for Searching Anticancer Derivatives of 2-Phenazinamines as Bcr-Abl Tyrosine Kinase Inhibitors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gajanan%20M.%20Sonwane">Gajanan M.

This strategy of designing compounds possessing selectivity over specific tyrosine kinase has been achieved through G-QSAR and molecular docking studies. The objective of this research has been to design newer 2-phenazinamine derivatives as Bcr-Abl tyrosine kinase inhibitors by G-QSAR, molecular docking studies followed by wet-lab studies along with evaluation of their anticancer potential. Computational chemistry was done by using VLife MDS 4.3 and Autodock 4.2 followed by wet-lab experiments for synthesizing 2-phenazinamine derivatives. The chemical structures of ligands in 2D were drawn by employing Chemdraw 2D Ultra 8.0 and were converted into 3D. These were optimized by using a semi-empirical method called MOPAC. The protein structure was retrieved from RCSC protein data bank as a PDB file. The binding interactions of protein and ligands were done by using PYMOL. The molecular properties of the designed compounds were predicted in silico by using Osiris property explorer. The parent compound 2-phenazinamine was synthesized by reduction of 2, 4-dinitro-N-phenyl-benzenamine in the presence of tin chloride followed by cyclization in the presence of nitrobenzene and magnesium sulfate. The derivatization at the amino function of 2-phenazinamine was performed by treating parent compound with various aldehydes in the presence of dicyclohexylcarbodiimide (DCC) and urea to afford 2-(2-chlorophenyl)-3-(phenazine-2-yl) thiazolidine-4-one. Synthesized 39 novel derivatives of 2-phenazinamine and performed antioxidant activity, anti antiproliferative on the bulb of onion and anticancer activity on cell line showing significant competition with marked blockbuster drug imatinib. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computer-aided%20drug%20design" title="computer-aided drug design">computer-aided drug design</a>, <a href="https://publications.waset.org/abstracts/search?q=tyrosin%20kinases" title=" tyrosin kinases"> tyrosin kinases</a>, <a href="https://publications.waset.org/abstracts/search?q=anticancer" title=" anticancer"> anticancer</a>, <a href="https://publications.waset.org/abstracts/search?q=docking" title=" docking"> docking</a> </p> <a href="https://publications.waset.org/abstracts/146402/application-of-computational-chemistry-for-searching-anticancer-derivatives-of-2-phenazinamines-as-bcr-abl-tyrosine-kinase-inhibitors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146402.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">140</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2196</span> Design and Characterization of Aromatase Inhibitor Loaded Nanoparticles for the Treatment of Breast Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harish%20K.%20Chandrawanshi">Harish K.

Letrozole loaded poly(D,L-lactide-co-glycolide acid) nanoparticles were prepared by solvent evaporation method using dichlorometane as solvent (oil phase) and polyvinyl alcohol (PVA) as aqueous phase. Prepared nanoparticles were characterized by particle size, infrared spectra, drug loading efficiency, drug entrapment efficiency and in vitro release and also evaluated for in vivo anticancer activity. The high speed homogenizer was used to produce stable nanoparticles of mean size range 198.35 ± 0.04 nm with high entrapment efficiency (69.86 ± 2.78%).

The significant system sustained the release of letrozole drug effectively and further investigation could exhibit its potential usefulness in breast cancer therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer%2Ftherapy" title="breast cancer/therapy">breast cancer/therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=letrozole" title=" letrozole"> letrozole</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title=" nanoparticles"> nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=PLGA" title=" PLGA "> PLGA </a> </p> <a href="https://publications.waset.org/abstracts/15006/design-and-characterization-of-aromatase-inhibitor-loaded-nanoparticles-for-the-treatment-of-breast-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15006.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">580</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2195</span> Comparative in silico and in vitro Study of N-(1-Methyl-2-Oxo-2-N-Methyl Anilino-Ethyl) Benzene Sulfonamide and Its Analogues as an Anticancer Agent</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pamita%20Awasthi">Pamita Awasthi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kirna"> Kirna</a>, <a href="https://publications.waset.org/abstracts/search?q=Shilpa%20Dogra"> Shilpa Dogra</a>, <a href="https://publications.waset.org/abstracts/search?q=Manu%20Vatsal"> Manu Vatsal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ritu%20Barthwal"> Ritu Barthwal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Doxorubicin, also known as adriamycin, is an anthracycline class of drug used in cancer chemotherapy. It is used in the treatment of non-Hodgkin’s lymphoma, multiple myeloma, acute leukemias, breast cancer, lung cancer, endometrium cancer and ovary cancers. It functions via intercalating DNA and ultimately killing cancer cells. The major side effects of doxorubicin are hair loss, myelosuppression, nausea & vomiting, oesophagitis, diarrhoea, heart damage and liver dysfunction. The minor modifications in the structure of compound exhibit large variation in the biological activity, has prompted us to carry out the synthesis of sulfonamide derivatives. Sulfonamide is an important feature with broad spectrum of biological activity such as antiviral, antifungal, diuretics, anti-inflammatory, antibacterial and anticancer activities. Structure of the synthesized compound N-(1-methyl-2-oxo-2-N-methyl anilino-ethyl)benzene sulfonamide confirmed by proton nuclear magnetic resonance (1H NMR),13C NMR, Mass and FTIR spectroscopic tools to assure the position of all protons and hence stereochemistry of the molecule. Further we have reported the binding potential of synthesized sulfonamide analogues in comparison to doxorubicin drug using Auto Dock 4.2 software. Computational binding energy (B.E.) and inhibitory constant (Ki) has been evaluated for the synthesized compound in comparison of doxorubicin against Poly (dA-dT).Poly (dA-dT) and Poly (dG-dC).Poly (dG-dC) sequences. The in vitro cytotoxic study against human breast cancer cell lines confirms the better anticancer activity of the synthesized compound over currently in use anticancer drug doxorubicin. The IC50 value of the synthesized compound is 7.12 µM where as for doxorubicin is 7.2 µ. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Doxorubicin" title="Doxorubicin">Doxorubicin</a>, <a href="https://publications.waset.org/abstracts/search?q=auto%20dock" title=" auto dock"> auto dock</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20silco" title=" in silco"> in silco</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20vitro" title=" in vitro"> in vitro</a> </p> <a href="https://publications.waset.org/abstracts/20279/comparative-in-silico-and-in-vitro-study-of-n-1-methyl-2-oxo-2-n-methyl-anilino-ethyl-benzene-sulfonamide-and-its-analogues-as-an-anticancer-agent" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20279.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">419</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2194</span> Concanavaline a Conjugated Bacterial Polyester Based PHBHHx Nanoparticles Loaded with Curcumin for the Ovarian Cancer Therapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Kilicay">E.

CUR is a promising anticancer agent for various cancer types. The aim of this study was to evaluate therapeutic potential of curcumin loaded PHBHHx nanoparticles (CUR-NPs) and concanavaline A conjugated curcumin loaded NPs (ConA-CUR NPs) for ovarian cancer treatment. ConA was covalently connected to the carboxylic group of nanoparticles by EDC/NHS activation method. In the ligand attachment experiment, the binding capacity of ConA on the surface of NPs was found about 90%. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) analysis showed that the prepared nanoparticles were smooth and spherical in shape. The size and zeta potential of prepared NPs were about 228±5 nm and −21.3 mV respectively. ConA-CUR NPs were characterized by FT-IR spectroscopy which confirmed the existence of CUR and ConA in the nanoparticles. The entrapment and loading efficiencies of different polymer/drug weight ratios, 1/0.125 PHBHHx/CUR= 1.25CUR-NPs; 1/0.25 PHBHHx/CUR= 2.5CUR-NPs; 1/0.5 PHBHHx/CUR= 5CUR-NPs, ConA-1.25CUR NPs, ConA-2.5CUR NPs and ConA-5CUR NPs were found to be ≈ 68%-16.8%; 55%-17.7 %; 45%-33.6%; 70%-15.7%; 60%-17%; 51%-30.2% respectively. In vitro drug release showed that the sustained release of curcumin was observed from CUR-NPs and ConA-CUR NPs over a period of 19 days. After binding of ConA, the release rate was slightly increased due to the migration of curcumin to the surface of the nanoparticles and the matrix integrities was decreased because of the conjugation reaction. This functionalized nanoparticles demonstrated high drug loading capacity, sustained drug release profile, and high and long term anticancer efficacy in human cancer cell lines. Anticancer activity of ConA-CUR NPs was proved by MTT assay and reconfirmed by apoptosis and necrosis assay. The anticancer activity of ConA-CUR NPs was measured in ovarian cancer cells (SKOV-3) and the results revealed that the ConA-CUR NPs had better tumor cells decline activity than free curcumin. The nacked nanoparticles have no cytotoxicity against human ovarian carcinoma cells. Thus the developed functionalized nanoformulation could be a promising candidate in cancer therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=curcumin" title="curcumin">curcumin</a>, <a href="https://publications.waset.org/abstracts/search?q=curcumin-PHBHHx%20nanoparticles" title=" curcumin-PHBHHx nanoparticles"> curcumin-PHBHHx nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=concanavalin%20A" title=" concanavalin A"> concanavalin A</a>, <a href="https://publications.waset.org/abstracts/search?q=concanavalin%20A-curcumin%20PHBHHx%20nanoparticles" title=" concanavalin A-curcumin PHBHHx nanoparticles"> concanavalin A-curcumin PHBHHx nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=PHBHHx%20nanoparticles" title=" PHBHHx nanoparticles"> PHBHHx nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=ovarian%20cancer%20cell" title=" ovarian cancer cell "> ovarian cancer cell </a> </p> <a href="https://publications.waset.org/abstracts/31868/concanavaline-a-conjugated-bacterial-polyester-based-phbhhx-nanoparticles-loaded-with-curcumin-for-the-ovarian-cancer-therapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31868.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">399</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2193</span> Ocular Delivery of Charged Drugs Using Iontophoresis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abraham%20J.%20Domb">Abraham J.

Most ocular diseases are treated with repeated topical applications administered as eye drops. Various attempts have been made to improve drug bioavailability by increasing both the retention of the drug in the pre-corneal area and the penetration of the drug through the cornea. However, currently marketed products are associated with vision blurring, irritability, patient discomfort, toxicity, low drug bioavailability, manufacturing difficulties and inadequate aqueous stability. It has been suggested to use iontophoresis for the non-invasive delivery of drugs. The iontophoretic device is composed of a control panel, two electrodes, a cylindrical well for the insertion of a disposable hydrogel, and a disposable hydrogel pellet. The drug-loaded hydrogel is attached to a cylindrical well at the edge of the electrode of the device and placed onto the eye. The device applies a variable electrical current that can vary from 0.1 mA to 1.5 mA for pre-set periods from 10 seconds to 300 seconds. The iontophoretic device developed in the lab was found to be effective in the delivery of the drugs: gentamicin, water-soluble steroids, and various anticancer agents. When testing in rabbits for safety, the device was considered to be non-toxic and effective. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=iontophoresis" title="iontophoresis">iontophoresis</a>, <a href="https://publications.waset.org/abstracts/search?q=eye%20disorder" title=" eye disorder"> eye disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20delivery" title=" drug delivery"> drug delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogel" title=" hydrogel"> hydrogel</a> </p> <a href="https://publications.waset.org/abstracts/164928/ocular-delivery-of-charged-drugs-using-iontophoresis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164928.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">80</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2192</span> Drug Delivery of Cyclophosphamide Functionalized Zigzag (8,0) CNT, Armchair (4,4) CNT, and Nanocone Complexes in Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Morteza%20Keshavarz">Morteza Keshavarz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, using density functional theory (DFT) thermodynamic stability and quantum molecular descriptors of cyclophoshphamide (an anticancer drug)-functionalized zigzag (8,0) CNT, armchair (4,4) CNT and nanocone complexes in water, for two attachment namely the sidewall and tip, is considered. Calculation of the total electronic energy (Et) and binding energy (Eb) of all complexes indicates that the most thermodynamic stability belongs to the sidewall-attachment of cyclophosphamide into functional nanocone. On the other hand, results from chemical hardness show that drug-functionalized zigzag (8,0) and armchair (4,4) complexes in the tip-attachment configuration possess the smallest and greatest chemical hardness, respectively. By computing the solvation energy, it is found that the solution of the drug and all complexes are spontaneous in water.

Further mitochondrial membrane damage was observed. The fate of cell death was found to be induced by apoptosis. For application purpose, we have developed a novel biodegradable, non-toxic polymer-based nanoparticle which has hydrophobically modified core for loading of the CuAA.

The cancer specificity was revealed both in in vitro and in vivo models. The cytotoxicity of the test compounds was analyzed against human cancer (HeLa) and normal (MRC5) cell lines using MTT colorimetric cell viability assay. IC50 values were determined and compared to reveal the cancer specificity of the test samples. The mechanistic study of the most active compound was investigated using Flow cytometry analyzing of the DNA content after PI (propidium iodide) staining. Data were analyzed with Tree Star FlowJo software using cell cycle analysis Dean-Jett-Fox module. The in vivo anticancer activity estimation experiments were carried out on mice with inoculated ascitic Ehrlich’s carcinoma at intraperitoneal introduction of doxorubicin and its zinc oxide compositions. It was shown that the nanosize zinc oxide film deposition on the drug surface leads to the selective anticancer activity of composites at the cellular level with the range of selectivity index (SI) from 4 (Starch+NaCMC+Dox+ZnO) to 200 (PEO(gel)+Dox+ZnO) which is higher than that of free Dox (SI = 56). The significant increase in vivo antitumor activity (by a factor of 2-2.5) and decrease of general toxicity of zinc oxide compositions of doxorubicin in the form of the above mentioned gels compared to free doxorubicin were shown on the model of inoculated Ehrlich's ascitic carcinoma. Mechanistic studies of anticancer activity revealed the cytostatic effect based on the high level of DNA biosynthesis inhibition at considerable low concentrations of zinc oxide compositions of doxorubicin. The results of studies in vitro and in vivo behavior of PEO+Dox+ZnO and Starch+NaCMC+Dox+ZnO composites confirm the high potential of the nanosize zinc oxide composites as a vector delivery system for future application in cancer chemotherapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anticancer%20activity" title="anticancer activity">anticancer activity</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20specificity" title=" cancer specificity"> cancer specificity</a>, <a href="https://publications.waset.org/abstracts/search?q=doxorubicin" title=" doxorubicin"> doxorubicin</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc%20oxide" title=" zinc oxide"> zinc oxide</a> </p> <a href="https://publications.waset.org/abstracts/1359/in-vitro-and-in-vivo-anticancer-activity-of-nanosize-zinc-oxide-composites-of-doxorubicin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1359.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">411</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2187</span> Prediction of Anticancer Potential of Curcumin Nanoparticles by Means of Quasi-Qsar Analysis Using Monte Carlo Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruchika%20Goyal">Ruchika Goyal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashwani%20Kumar"> Ashwani Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandeep%20Jain"> Sandeep Jain</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The experimental data for anticancer potential of curcumin nanoparticles was calculated by means of eclectic data.

Docetaxel solid dispersions were formulated with Soluplus in different weight ratios. Freeze drying method was used to prepare the solid dispersions. Solubility of the solid dispersions were evaluated respectively and the optimized of drug-solubilizers ratio systems were characterized with different analytical methods like Differential scanning calorimeter (DSC), Scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) to confirm the formation of complexes between drug and solubilizers. The solubility data revealed an overall improvement in solubility for all SD formulations. The ternary combination 1:5:2 gave the highest increase in solubility that is approximately 3 folds from the pure drug, suggesting the optimum drug-solubilizers ratio system. This data corresponds with the DSC and SEM analyses, which demonstrates presence of drug in amorphous state and the dispersion in the solubilizers in molecular level. The solubility of the poorly soluble drug, docetaxel was enhanced through preparation of solid dispersion formulations employing freeze drying method. Solid dispersion with multiple carrier system shows better solubility compared to single carrier system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=docetaxel" title="docetaxel">docetaxel</a>, <a href="https://publications.waset.org/abstracts/search?q=freeze%20drying" title=" freeze drying"> freeze drying</a>, <a href="https://publications.waset.org/abstracts/search?q=soluplus" title=" soluplus"> soluplus</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20dispersion%20technique" title=" solid dispersion technique"> solid dispersion technique</a> </p> <a href="https://publications.waset.org/abstracts/17833/solubility-enhancement-of-poorly-soluble-anticancer-drug-docetaxel-using-a-novel-polymer-soluplus-via-solid-dispersion-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17833.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">503</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2185</span> Isolation, Characterization and Quantitation of Anticancer Constituent from Chloroform Extract of N. arbortristis L.

Objective: The objective of the present study was to isolate and characterize anticancer phytoconstituents from N. arbortristis L. leaves based on bioactivity guided fractionation. Method: Different extracts of the leaves of the plant were prepared by Soxhlet extractor. Each extract was evaluated for anticancer activity against HL-60 cell lines. Chloroform and HA extract showed potent anticancer activity and hence were selected for fractionation. Fraction C1 from chloroform extract was found to be most potent amongst all when tested against three cell lines (HL-60, A-549, and HCT-116) and thus was selected for further fractionation and a pure compound CP-01 was isolated. RP-HPLC method has been developed for quantification of isolated compound by using Kinetex C-18 column with gradient elution at 0.7 mL/min using mobile phase containing potassium dihydrogen phosphate (0.01 M, pH 3.0) with acetonitrile. The wavelength of maximum absorption (λₘₐₓ) selected was 210 nm. Results: The structure of potent anticancer CP-01 was determined on the basis spectroscopic methods like IR, 1H-NMR, ¹³C-NMR and Mass Spectrometry and it was characterized as 1,1,2-tris(2’,4’-di-tert-butylbenzene)-4,4-dimethyl-pent-1-ene. The content of CP-01 was found to be 0.88 %w/w of chloroform extract and 0.08 %w/w of N.arbortristis leaves. Conclusion: The study supports the traditional use of N. arbortristis as anticancer herb & the identified compound CP-01 can serve as an excellent lead to develop potent and safe anticancer drugs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anticancer" title="anticancer">anticancer</a>, <a href="https://publications.waset.org/abstracts/search?q=HL-60%20cell%20lines" title=" HL-60 cell lines"> HL-60 cell lines</a>, <a href="https://publications.waset.org/abstracts/search?q=Nyctanthes%20arbor-tristis" title=" Nyctanthes arbor-tristis"> Nyctanthes arbor-tristis</a>, <a href="https://publications.waset.org/abstracts/search?q=RP-HPLC" title=" RP-HPLC"> RP-HPLC</a> </p> <a href="https://publications.waset.org/abstracts/104616/isolation-characterization-and-quantitation-of-anticancer-constituent-from-chloroform-extract-of-n-arbortristis-l-leaves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104616.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2184</span> Evaluation of Anticancer and Antioxidant Activity of Purified Lovastatin from Aspergillus terreus (KM017963)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bhargavi%20Santebennur%20Dwarakanath">Bhargavi Santebennur Dwarakanath</a>, <a href="https://publications.waset.org/abstracts/search?q=Praveen%20Vadakke%20Kamath"> Praveen Vadakke Kamath</a>, <a href="https://publications.waset.org/abstracts/search?q=Savitha%20Janakiraman"> Savitha Janakiraman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cervical cancer is one of the leading causes of mortality in women and is the second most common malignancy worldwide. Lovastatin, a non polar, anticholesterol drug which also exerts antitumour activity in vitro. In the present study, lovastatin from Aspergillus terreus (KM017963) was purified by adsoprtion chromatography and evaluated for its anticancer and anti-oxidant properties in human cervical cancer cell lines (HeLa). The growth inhibitory and proapoptotic effects of purified lovastatin on HeLa cell lines were investigated by determining its influence on cytotoxicity, Mitochondrial Membrane Potential (MMP), DNA fragmentation and antioxidant property (Hydroxy radical scavenging effect and the levels of total reduced glutathione). Flow cytometry analysis by propidium iodide staining confirmed the induction of apoptotic cell death and revealed cell cycle arrest at G0/G1 phase. Results of the study give leads for anticancer effects of lovastatin and its potential efficacy in the chemotherapy of cervical cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title="apoptosis">apoptosis</a>, <a href="https://publications.waset.org/abstracts/search?q=Aspergillus%20terreus" title=" Aspergillus terreus"> Aspergillus terreus</a>, <a href="https://publications.waset.org/abstracts/search?q=cervical%20cancer" title=" cervical cancer"> cervical cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=lovastatin" title=" lovastatin"> lovastatin</a> </p> <a href="https://publications.waset.org/abstracts/49846/evaluation-of-anticancer-and-antioxidant-activity-of-purified-lovastatin-from-aspergillus-terreus-km017963" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49846.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">307</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2183</span> Management of Therapeutic Anticancer at Oran Teaching Hospital, Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Boulenouar">S.

Management and supply is therefore to provide the different services of the facility goods and services in required quantity and quality. The permanent availability of drugs in the facilities is very difficult because most face many difficulties at the inventory management and drug supplies. Therefore, it is necessary for each health facility to know the causes for the malfunction of its management system to cope with them. It is in this context that we have undertaken to conduct this study to know the causes which should be taken into consideration by the concerned authorities to carry out their mission, which is to provide quality health care for the population. In terms of financial resources, the budget for medicines represents a significant part of the budget of the pharmacy. Our study shows that the share of the hospital budget reserved for the drugs procurement represent on average 70% of the budget of the pharmacy. The results show a state of lack of anticancer drugs at Oran teaching hospital. The analysis of the management process allowed us to know the level that the problem of stock-outs of anti-cancer drugs is at. Suggestions were made to that effect to improve the availability for these products and to respond better to the needs of patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anticancer%20drugs" title="anticancer drugs">anticancer drugs</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20care%20facility" title=" health care facility"> health care facility</a>, <a href="https://publications.waset.org/abstracts/search?q=budget" title=" budget"> budget</a>, <a href="https://publications.waset.org/abstracts/search?q=hospital%20pharmacist" title=" hospital pharmacist"> hospital pharmacist</a>, <a href="https://publications.waset.org/abstracts/search?q=hospital%20service" title=" hospital service"> hospital service</a> </p> <a href="https://publications.waset.org/abstracts/38506/management-of-therapeutic-anticancer-at-oran-teaching-hospital-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38506.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">446</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2182</span> Anti-cancer Activity of Cassava Leaves (Manihot esculenta Crantz.)
