A series of novel azole-diphenylpyrimidine derivatives (AzDPPYs) were synthesized and biologically evaluated as potent EGFR(T790M) inhibitors. Among these analogues, the most active inhibitor 6e not only displayed high activity against EGFR(T790M/L858R) kinase (IC50 = 33 nM), but also was able to repress the replication of H1975 cells harboring EGFR(T790M) mutation at a concentration of 0.118 mu mol/L. In contrast to the lead compound rociletinib, 6e slightly reduces the key EGFRT790M-minduced drug resistance. Significantly, inhibitor 6e demonstrates high selectivity (SI = 299.3) for T790M-containing EGFR mutants over wild type EGFR, hinting that it will cause less side effects. (C) 2016 Elsevier Ltd.
