Design, synthesis and biological evaluation of 2-amino-4-(1,2,4-triazol)pyridine derivatives as potent EGFR inhibitors to overcome TKI-resistance

摘要

A new class of 2-amino-4-(1,2,4-triazol)pyridine derivatives were designed and synthesized as potent epidermal growth factor receptor inhibitors. In particular, compound 10c exhibited significant inhibitory against EGFR(L858R/T790M), and also displayed potent anti-proliferative activity against non-small cell lung cancer cell line H1975. Besides, compound 10j showed potent inhibitory activity against glioblastoma cell line U87-EGFRvIII, which was at least 3-fold more potent than Osimertinib and 25-fold superior to Lazertinib. Moreover, molecular modeling and molecular dynamics simulations disclosed the binding model of the most active compound to the domain of EGFR. This contribution provides 2-amino-4-(1,2,4-triazol)pyridines as a new scaffold for EGFR(T790M) and/or EGFRvIII inhibitor. (C) 2019 Elsevier Masson SAS. All rights reserved.
