Abstract

A series of novel thiapyran-pyrimidine derivatives (10a-10h, 11a-11g, 12a-12f, 13a-13f, 14a-14f) were synthesized and their antiproliferative activities were tested. Most of the target compounds showed good activity on one or more Cancer cell lines but low activity on human normal cell LO2. The most promising compound 13a exhibited the similar IC50 values on A549 and H1975 cell lines to the lead drug Olmutinib, and exhibited excellent activity and selectivity on EGFRT790M/L858R in the kinase experiment. AO and Hoechst33258 staining indicated that 13a could effectively induce H1975 cells Apoptosis. Cell cycle and Apoptosis analysis suggested that 13a could block Cancer cells in G2/M phase and induce into late Apoptosis in a manner of concentration-dependent. The structure-activity relationship of 13a was analyzed to explore its mechanism. All the results showed that 13a was a promising EGFR inhibitor.
