Abstract

A novel series of 6-alkenylamides of 4-anilinothieno[2,3-d]pyrimidine derivatives was designed, synthesized and evaluated as irreversible inhibitors of the epidermal growth factor receptor (EGFR). Most of the compounds exhibited good potency against EGFR wild type (EGFR wt) and EGFR T790M/L858R. Among these, the half-maximal inhibitory concentration (IC50) values of 17 compounds against EGFR wt were less than 0.020μM, and those of 12 compounds were less than 0.010μM. The IC50 values of 10 compounds against EGFR T790M/L858R were less than 0.005μM. Compounds 8l, 9n, 9o, 9q and 9v almost completely blocked the phosphorylation of EGFR in the A431 cell line at 1μM. Compounds 8l, 9n, 9o, 9q and 9v blocked the autophosphorylation of EGFR in NCI-H1975 cells at high concentration (1μM), and compound 8l was confirmed to be an irreversible inhibitor through the dilution method.
