KRASG12C is the most prevalent KRAS mutation in non-small cell lung cancer (NSCLC) and has emerged as a promising therapeutic target. Herein, two series of novel 4(1H)-quinolinone and urea compounds were designed based on the reported KRASG12C inhibitor SH-9. Many compounds showed significantly growth inhibitory activity against human NSCLC cells with KRASG12C mutation in cell viability assays. Compound
KRAS G12C是非小细胞肺癌 (NSCLC) 中最普遍的 KRAS 突变,已成为一个有前途的治疗靶点。在此,基于已报道的 KRAS G12C抑制剂 SH-9 ,设计了两个系列的新型 4(1 H )-喹啉酮和尿素化合物。许多化合物在细胞活力测定中显示出对具有 KRAS G12C突变的人 NSCLC 细胞的显着生长抑制活性。化合物20a在 KRAS G12C突变体 NCI–H358 细胞中表现出 0.5 μM 的 IC 50值,选择性是 KRAS WT NCI–H2228 细胞的 21 倍。LC-MS 分析表明化合物14c、14h和20a共价结合 KRAS G12C而不是 KRAS WT。此外,这些化合物可以通过阻断 SOS1 介导的 GDP/GTP 交换,显着捕获处于非活性状态的 KRAS G12C。此外,用20a剂量依赖性地处理 NCI–H358 而不是 NCI–H2228 细胞会降低
