摘要
We designed a series of 2-methylpyrimidine derivatives as new BCR-ABL inhibitors using scaffold-hopping strategy.These synthetic compounds exhibited significant inhibition against a broad spectrum of Bcr-Abl mutants including the gatekeeper T315I mutant.Compound 7u showed very potent kinase inhibitory activities against Bcr-Abl WT,Bcr-Abl E255K,Bcr-Abl Q252H,Bcr-Abl G250E and Bcr-Abl T315I,with IC50 values of 0.13 nM,0.17 nM,0.24 nM,0.19 nM and 0.65μM,respectively.This compound also displayed anti-proliferation activity against K562 cell line with an IC50 value of 1.1 nM,thus representing a new lead for further optimization.
