we sought inhibitors of T790M-containing EGFR mutants with selectivity over wtEGFR. We describe the evolution of HTS hits derived from Jak2/Tyk2 inhibitors into selective EGFR inhibitors. X-ray crystal structures revealed two distinct binding modes and enabled the design of a selective series of novel diaminopyrimidine-based inhibitors with good potency against T790M-containing mutants of EGFR, high
表皮生长因子受体(EGFR)激酶结构域内的激活突变,通常是L858R或外显子19内的缺失,增加了EGFR驱动的细胞增殖和存活,并与非小细胞肺癌患者对EGFR抑制剂埃洛替尼和吉非替尼的令人印象深刻的反应相关。大约60%的对这些药物的耐药性是由EGFR激酶结构域内的单个次级突变驱动的,特别是用蛋氨酸(T790M)替代了网守残基苏氨酸790。由于与抑制野生型EGFR(wtEGFR)有关的剂量限制性毒性,我们寻求了对T790M EGFR突变体具有抑制作用的抑制剂,其选择性优于wtEGFR。我们描述了来自Jak2 / Tyk2抑制剂的HTS命中进化为选择性EGFR抑制剂。
