Two series of novel 4-phenoxypyridine derivatives containing imidazole-4-carboxamide and 4-methyl-5-oxo-4,5-dihydro-1,2,4-triazole-3-carboxamide moieties were synthesized and evaluated for their in vitro inhibitory activities against c-Met kinase and antiproliferative activities against MKN-45, A549 and H460 cancer cell lines. The results indicated that most of the compounds showed moderate to good
合成了两个系列的新型 4-苯氧基吡啶衍生物,含有咪唑-4-甲酰胺和 4-甲基-5-氧代-4,5-二氢-1,2,4-三唑-3-甲酰胺部分,并评估了它们的体外抑制作用对 c-Met 激酶的活性和对 MKN-45、A549 和 H460 癌细胞系的抗增殖活性。结果表明,大多数化合物显示出中等至良好的抗肿瘤活性。最有希望的化合物T14(c-Met IC 50值为 0.012 μM)对 MKN-45、A549 和 H460 细胞系显示出显着的抗增殖活性,IC 50值分别为 0.64 μM、1.92 μM 和 2.68 μM。他们初步的构效关系(SARs)研究表明,4-咪唑酰胺更优选作为连接部分,末端苯环上的吸电子基团(尤其是卤素基团)有利于提高抗肿瘤活性。
