throughput screening and subsequent hit validation identified 4-isopropyl-3-(2-((1-phenylethyl)amino)pyrimidin-4-yl)oxazolidin-2-one as a potent inhibitor of IDH1R132H. Synthesis of the four separate stereoisomers identified the (S,S)-diastereomer (IDH125, 1f) as the most potent isomer. This also showed reasonable cellular activity and excellent selectivity vs IDH1wt. Initial structure-activity relationship
高通量筛选和随后的命中验证确定了4-异丙基-3-(2-(((1-苯乙基)氨基)嘧啶-4-基)恶唑烷-2--2-酮是IDH1R132H的有效抑制剂。四种单独的立体异构体的合成确定了(S,S)-非对映异构体(IDH125,1f)是最有效的异构体。与IDH1wt相比,这也显示出合理的细胞活性和出色的选择性。初步的结构-活性关系探索确定了关键的公差和优化的潜力。X射线晶体学确定了一种适合抑制剂的功能相关的变构结合位点,该位点可以穿透血脑屏障,并有助于合理优化。增强效力并调节已鉴定的理化性质(S,
