Addressing resistance to third-generation EGFR TKIs such as osimertinib via the EGFRC797S mutation remains a highly unmet need in EGFR-driven non-small-cell lung cancer (NSCLC). Herein, we present the discovery of the allosteric EGFR inhibitor 57, a novel fourth-generation inhibitor to overcome EGFRC797S-mediated resistance in patients harboring the activating EGFRL858R mutation. 57 exhibits an improved
在 EGFR 驱动的非小细胞肺癌 (NSCLC) 中,通过 EGFR C797S突变解决对奥希替尼等第三代 EGFR TKI 的耐药性仍然是一个高度未满足的需求。在此,我们介绍了变构 EGFR 抑制剂57的发现,这是一种新型的第四代抑制剂,可克服携带激活 EGFR L858R突变的患者的 EGFR C797S介导的耐药性。与以前的别构 EGFR 抑制剂相比,57显示出改进的效力。据我们所知,57是第一个在突变 EGFR L858R/C797S肿瘤模型中表现出强大的肿瘤消退的变构 EGFR 抑制剂。此外,57在 H1975 EGFR L858R/T790M NSCLC 异种移植模型中具有活性,并且与单药相比,与奥希替尼联用显示出更好的疗效。我们的数据强调了57作为针对 EGFR L858R/C797S和 EGFR L858R/T790M/C797S的单一药物以及作为 EGFR L858R 和
