Blocking c-Met kinase activity by small-molecule inhibitors has been identified as a promising approach for the treatment of cancers. Herein, we described the design, synthesis, and biological evaluation of a series of 4-phenoxypyridine-based 3-oxo-3,4-dihydroquinoxaline derivatives as c-Met kinase inhibitors. Inhibitory activitives against c-Met kinase evaluation indicated that most of compounds showed
通过小分子抑制剂阻断c-Met激酶活性已被认为是治疗癌症的有前途的方法。在这里,我们描述了一系列基于4-苯氧吡啶的3-氧代-3,4-二氢喹喔啉衍生物作为c-Met激酶抑制剂的设计,合成和生物学评估。对c-Met激酶的抑制活性评估表明,大多数化合物在体外均表现出出色的c-Met激酶活性,十种化合物(23a,23e,23f,23l,23r,23s,23v,23w,23x和23y)的IC 50值)小于10.00 nM。值得注意的是,它们中的三个(23v,23w和23y)显示出显着的效价,IC 50值分别为2.31 nM,1.91 nM和2.44 nM,因此它们比阳性对照药物foretinib(c-Met,IC 50 = 2.53 nM)。细胞毒性评估表明,最有希望的化合物23w对A549,H460和HT-29细胞系表现出显着的细胞毒性,IC 50值分别为1.57μM,0.94μM和0.65μM
