Two series of novel 1,5-naphthyridine and 1,6-naphthyridine derivatives were designed and synthesized based on the c-Met kinase inhibitor MK-2461 under the guidance of scaffold hopping strategy. All were tested on c-Met kinase and in vitro anti-tumor activities against Hela and A549 cell lines. The results indicated that 1,6-naphthyridine was a more promising c-Met inhibitory structure core compared
在支架跳跃策略的指导下,基于c-Met激酶抑制剂MK-2461设计并合成了两个系列的新型1,5-萘啶和1,6-萘啶衍生物。所有测试均针对c-Met激酶以及针对Hela和A549细胞系的体外抗肿瘤活性。结果表明,与1,5-萘啶相比,1,6-萘啶是更有前途的c-Met抑制结构核心。其中,26b和26c表现出最好的酶和细胞毒性活性。Western blot实验表明26c的细胞毒活性可能部分是通过抑制c-Met激酶的磷酸化来实现的。
