proliferation, differentiation, and migration. Recent progress revealed that directly target KRAS G12C with allosteric inhibitors that covalently bind to the switch Ⅱ pocket is feasible. Herein, series of pyrrolo[2,3-d]pyrimidine derivatives were designed and synthesized through systematic structural optimization, leading to the discovery of compound 2-((S)-1-acryloyl-4-(2-(((2R,7aS)-2-fluorohexahydro-1H-pyrro
致癌基因KRAS通过调节细胞增殖、分化和迁移在人类癌症中起主要作用。最近的进展表明,用共价结合开关Ⅱ口袋的变构抑制剂直接靶向 KRAS G12C 是可行的。在此,通过系统的结构优化,设计并合成了一系列吡咯并[2,3- d ]嘧啶衍生物,从而发现了化合物2-(( S )-1-acryloyl-4-(2-((( ( 2R , 7aS )-2-fluorohexahydro-1 H -pyrrolizin-7a(5 H )-yl)methoxy)-7-methyl-6-(8-methylnaphthalen-1-yl)-7 H -pyrrolo[2,3- d ]嘧啶-4-基)哌嗪-2-基)乙腈(50 ) 具有高 KRAS/SOS1 抑制效力 (IC 50 = 0.21 μM) 和对携带 KRAS p.G12C 的癌细胞的强抗增殖活性。化合物50还表现出令人满意的选择性、温和的药代动力学特征和良好
