continuous efforts to discover novel c-Met inhibitors as antitumor agents, four series of thiazole/thiadiazole carboxamide-derived analogues were designed, synthesised, and evaluated for the in vitro activity against c-Met and four human cancer cell lines. After five cycles of optimisation on structure–activity relationship, compound 51am was found to be the most promising inhibitor in both biochemical and
摘要 作为我们不断努力发现新型 c-Met 抑制剂作为抗肿瘤药物的一部分,我们设计、合成了四个系列的噻唑/噻二唑甲酰胺衍生类似物,并评估了其针对 c-Met 和四种人类癌细胞系的体外活性。经过五个周期的构效关系优化后,发现化合物51am在生化和细胞分析中都是最有前途的抑制剂。此外,51am对几种 c-Met 突变体表现出效力。从机制上讲,51am不仅诱导 MKN-45 细胞的细胞周期停滞和凋亡,而且抑制细胞和无细胞系统中的 c-Met 磷酸化。它还在 BALB/c 小鼠中表现出良好的药代动力学特征。此外, 51am与 c-Met 和 VEGFR-2 的结合模式为选择性 c-Met 抑制剂的发现提供了新的见解。总而言之,这些结果表明51am可能是值得进一步开发的抗肿瘤候选药物。
