With the aim to overcome the drug resistance induced by the EGFR T790M mutation (EGFRT790M), herein, a family of diphenylpyrimidine derivatives (Sty-DPPYs) bearing a C-2 (E)-4-(styryl)aniline functionality were designed and synthesized as potential EGFRT790M inhibitors. Among them, the compound 10e displayed strong potency against the EGFRT790M enzyme, with the IC50 of 11.0nM. Compound 10e also showed
为了克服由
EGFR T790M突变(
EGFRT790M)诱导的耐药性,本文设计并合成了具有C-2(E)-4-(
苯乙烯基)
苯胺官能度的二
苯基嘧啶衍
生物(Sty-
DPPYs)家族。作为潜在的
EGFRT790M
抑制剂。其中,化合物10e对
EGFRT790M酶具有很强的效力,IC50为11.0nM。化合物10e还显示出比
罗西替尼(SI = 21.4)更高的SI值(SI = 49.0),表明其副作用较小。另外,化合物10e可以在2.91μM的浓度范围内有效抑制具有
EGFRT790M突变的H1975细胞的增殖。值得注意的是,化合物10e对正常的HBE细胞毒性低(IC50 =22.48μM)。
