In the presence of cyanide ions, this type of compound exhibits an ICT mechanism associated with the addition of the cyanide ion to the β position of the dicyanovinyl group, due to the strong electron-withdrawing effect of the cyano groups. These structural changes caused by the addition reaction are accompanied by changes in the probe’s absorption and emission. In this work, we report a thiophene-based dicyanovinyl derivative and its prospective application as an anion chemosensor. The photophysical characterization was carried out in acetonitrile and aqueous acetonitrile solutions. Preliminary sensing assays in the presence of various anions of biological, medicinal, and environmental relevance were conducted, and the interaction with CN − was further explored through spectrophotometric titrations.","PeriodicalId":11441,"journal":{"name":"ECSOC-25","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84235627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have recently described the easy green synthesis of purpurogallin from pyrogallol catalyzed by a copper complex or by vegetable oxidases.

In this study, the cytotoxic activity of various β -amino alcohols derivatives from eugenol was evaluated in AGS (gastric cancer) and A549 (lung cancer) cell lines. The results show that some structural modi-fications resulted in enhanced cytotoxic activity towards cancer cells. In addition, the activation of caspase-3 and hence apoptosis induced by these molecules, was also explored. Considering the ob-tained results, some structure/activity relationships can be drawn, which may guide future structural improvements for anticancer agents.","PeriodicalId":11441,"journal":{"name":"ECSOC-25","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89738434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
