third-generation EGFR inhibitors. Herein, we report the discovery of potent and highly selective inhibitors of EGFR exon 19 p.E746_A750del/EGFR exon 20 p.T790M/EGFR exon 20 p.C797S (d746-750/T790M/C797S) mutant, which were derived via two-track virtual screening and de novo design. This two-track approach was performed so as to maximize and minimize the inhibitory activity against the triple mutant and the
尽管单突变表皮生长因子受体(EGFR)激酶的抑制剂可有效治疗非小细胞肺癌(NSCLC),但由于各种具有耐药性的双重和三重EGFR突变体的出现,其临床疗效受到了限制。因此,鉴定对第一,第二和第三代EGFR抑制剂具有抗性的三重突变EGFR的有效和选择性抑制剂已变得迫在眉睫。在此,我们报告了发现了有效且高度选择性的EGFR外显子19 p.E746_A750del / EGFR外显子20 p.T790M / EGFR外显子20 p.C797S(d746-750 / T790M / C797S)突变体的抑制剂,这些突变体是通过两个跟踪虚拟筛选和从头设计。进行这种两轨方法以便最大化和最小化分别对三重突变体和野生型的抑制活性。最初命中化合物的广泛化学修饰导致鉴定了d746-750 / T790M / C797S突变体的几种低纳摩尔抑制剂。其中,与野生型相比,两种化合物在抑制EGFRd746-750 / T790M
