2-amino-3-benzylthiopyridines against c-Met were designed by means of bioisosteric replacement and docking analysis. Optimization of the 2-amino-3-benzylthiopyridine scaffold led to the identification of compound (R)-10b displaying c-Met inhibition with an IC50 up to 7.7 nM. In the cytotoxic evaluation, compound (R)-10b effectively inhibited the proliferation of c-Met addictive human cancer cell lines
一系列的2-氨基Ñ -benzylpyridine -3- carboxnamides,2-氨基Ñ针对c-Met的-benzylpyridine -3-磺酰胺和2-氨基-3- benzylthiopyridines通过生物电子等排更换和对接分析来设计。对2-氨基-3-苄基硫代吡啶骨架的优化导致鉴定化合物(R)-10b,其显示出c-Met抑制,IC 50高达7.7 nM。在细胞毒性评估中,化合物(R)-10b有效抑制c-Met上瘾的人类癌细胞系的增殖(IC 50从0.19到0.71μM)和c-Met激活介导的细胞转移。在100 mg / Kg的剂量下,(R)-10b明显抑制了NIH-3T3 / TPR-Met异种移植模型中的肿瘤生长(45%)。值得注意的是,(R)-10b可以克服c-Met激活介导的吉非替尼耐药性,这表明其在药物组合中的潜在用途。综上所述,首先公开了2-氨基-3-苄基硫代吡啶
