cancers. Inhibition of mutant IDH1 (mIDH1) with small molecules has been clinically validated as a promising therapeutic treatment for acute myeloid leukemia and multiple solid tumors. Herein, we report the discovery and optimization of a series of quinolinones to provide potent and orally bioavailable mIDH1 inhibitors with selectivity over wild-type IDH1. The X-ray structure of an early lead 24 in complex
在各种人类癌症中经常发现异柠檬酸脱氢酶1(IDH1)中精氨酸残基(R132)的突变。小分子抑制突变IDH1(mIDH1)已被临床验证为急性髓细胞性白血病和多发实体瘤的有前途的治疗方法。在此,我们报告了一系列喹啉酮的发现和优化,以提供对野生型IDH1具有选择性的有效和口服生物利用性mIDH1抑制剂。与mIDH1-R132H结合的早期铅24的X射线结构表明,该抑制剂出乎意料地结合了变构位点。努力改善24的体外和体内吸收,分布,代谢和排泄(ADME)特性,产生了临床前候选药物63。
