representative EGFR inhibitors have been approved for clinical use, it is highly desirable to develop highly potent and selective EGFR inhibitors with novel scaffolds because of the occurrence of acquired resistance after treatment. Here we first demonstrate that the 4-indolyl quinazoline derivatives could potently inhibit EGFR in vitro and in vivo, of which YS-67 effectively and selectively inhibits EGFR[WT]
靶向表皮生长因子受体 (EGFR) 已被公认为治疗非小细胞肺癌 (NSCLC) 的有效策略。尽管几种具有代表性的 EGFR 抑制剂已被批准用于临床,但由于治疗后会出现获得性耐药,因此非常需要开发具有新型支架的高效和选择性 EGFR 抑制剂。在这里,我们首先证明 4-吲哚基喹唑啉衍生物可以在体外和体内有效抑制 EGFR,其中 YS-67 有效和选择性地抑制 EGFR[WT] (IC50 = 5.2 nM)、EGFR [d746-750] (IC50 = 9.6 nM) 和 EGFR [L858R] (IC50 = 1.9 nM)。TREEspot™ 激酶相互作用图进一步揭示了对 468 种激酶的结合选择性。YS-67 不仅有效抑制 p-EGFR 和 p-AKT,还有效抑制 A549 (IC50 = 4.1 μM)、PC-9 (IC50 = 0.5 μM) 和 A431 细胞 (IC50 = 2
