Synthesis of 2-alkylthio-N-(quinazolin-2-yl)benzenesulfonamide derivatives: anticancer activity, QSAR studies, and metabolic stability.
Abstract: A new series of 2-alkylthio-N-(quinazolin-2-yl)benzenesulfonamide derivatives have been synthesized and evaluated in vitro for their antiproliferative activity by MTT assay against cancer cell lines HCT-116, MCF-7, and HeLa as well as the NCI-60 human tumor cell lines screen. In NCI screen, three compounds inhibited approximately 50% growth of RPMI-8226 and A549/ATCC cell lines. The mean of IC50 calculated in MTT assays for three tested cell lines was about 45 μM for four compounds. The QSAR allowed finding statistically significant OPLS models for HeLa cell line. Metabolic stability in vitro studies indicated favorable and unfavorable structural elements. The good metabolic stability, with t1/2 higher than 40 min, was observed for three derivatives, which together with their antiproliferative activity and good ADMET profile, makes them good leading structures for further research.
期刊介绍：
"Monatshefte für Chemie/Chemical Monthly" was originally conceived as an Austrian journal of chemistry. It has evolved into an international journal covering all branches of chemistry. Featuring the most recent advances in research in analytical chemistry, biochemistry, inorganic, medicinal, organic, physical, structural, and theoretical chemistry, Chemical Monthly publishes refereed original papers and a section entitled "Short Communications". Reviews, symposia in print, and issues devoted to special fields will also be considered.
