In order to search for new antitumor drugs with high efficiency, a series of novel quinazoline derivatives containing acrylamide group were designed, synthesized and evaluated for antiproliferative activity against four human cancer cell lines (PC-3, H1975, A549 and Eca-109) using MTT assay in vitro. Among them, compound N-(3-((6-((4-cyanobenzyl)oxy)-7-methoxyquinazolin-4-yl)amino)phenyl)acrylamide (14m) showed good anti-tumor proliferation activity against four tested cancer cell lines, with IC50 values of 1.09 ± 0.04µM to H1975 cell. The antitumor activity was significantly better than that of 5-FU. Further mechanism studies showed that compound 14m inhibit the proliferation and migration of H1975 cells, block its cell cycle at G2/M phase and induce its apoptosis in a concentration dependent and time-dependent manner.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
