Discovery of aminopyridine-containing spiro derivatives as EGFR mutations inhibitors.

ABSTRACT: Neratinib is an oral pan HER inhibitor, that irreversibly inhibits EGFR and HER2 and was proven to be effective against multiple EGFR mutations. In previous study, we reported spiro [indoline-3, 4'-piperidine]-2-ones as anticancer agents. In this study, we designed aminopyridine-containing spiro [indoline-3,4'-piperidine] derivatives A1-A4 using Neratinib and spiro [indoline-3, 4'-piperidine]-2-one compound patented as lead structure, then replaced piperidine with cyclopropane to obtain B1-B7 and replaced indoline with benzmorpholine to get C1-C4 and D1-D2. We synthesized these compounds and evaluated their residual activities under 0.5 M drug concentration on EGFR and ERBB2. Most of compounds showed stronger inhibition on EGFR-wt and ERBB2, in which A1-A4
