All analogs were screened against three cancer cell lines (prostate, colon and breast).Results: Several active compounds were identified viain vitro cancer cell line screening with the most potent compound (26) in the nanomolar range.Conclusion: Compound 26 and analogs showing the most potent inhibitory activity may be considered for further design and optimization efforts as anticancer hit scaffolds.","PeriodicalId":39133,"journal":{"name":"Open Medicinal Chemistry Journal","volume":"12 ","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2018-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5817852/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35872443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pH of formulation ranges between 5.8 ±.001 to 6.8 ±.005 indicating that no mucosal irritation is expected as pH was in acceptable range. Invitro drug release from the mucoadhesive insitu gel formulations showed immediate drug release pattern with a maximum drug release of 97.02 ±0.54% for optimized G5 formulation within 20min. Exvivo permeation studies of optimized formulation G5 and control formulation was estimated. Exvivo permeation studies of G5 insitu formulation done for a period of 12 h resulted in slow, sustained release and greater permeability significance(P <0.05) through nasal mucosa when compared to control. Histopathological studies showed that G5 formulation was safer for nasal administration without any irritation. The stability studies indicated that gels were stable over 45 days in refrigerated condition (4±2ºC).Conclusion: The intranasal insitu gelling system is a promising novel drug delivery system for an antiepileptic drug lamotrigine which could enhance nasal residence time with increased viscosity and mucoadhesive character and provided better release profile of drug for treating acute epileptic conditions.","PeriodicalId":39133,"journal":{"name":"Open Medicinal Chemistry Journal","volume":"11 ","pages":"222-244"},"PeriodicalIF":0.0,"publicationDate":"2017-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5769127/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35791963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This virus has caused the majority of deaths in human. There are no proper vaccinations and medications available for EVD.

Moreover, the 3D-QSAR model also showed the best r2 value 0.99 using PLS factor. Thereby, we found the higher F value, which demonstrated the statistical significance of both the models. Furthermore, homological modeling and molecular docking study were performed to analyze the affinity of the potent lead.
