A series of novel 4-phenoxyquinoline derivatives containing pyridazinone moiety were synthesized and evaluated for their in vitro cytotoxic activity against five cancer cell lines (HT-29, H460, A549, MKN-45, and U87MG). Most of the compounds exhibited moderate-to-significant cytotoxicity and high selectivity against one or more cell lines. Compounds 15a, 20a, 15b, 15c, 20d, and 16e were further examined
合成了一系列含有哒嗪酮部分的新型4-苯氧基喹啉衍生物,并评估了它们对五种癌细胞系(HT-29,H460,A549,MKN-45和U87MG)的体外细胞毒活性。大多数化合物对一种或多种细胞系表现出中度至显着的细胞毒性和高选择性。进一步检查化合物15a,20a,15b,15c,20d和16e对c-Met激酶的抑制活性。最有前途的化合物15a(c-Met的半数最大抑制浓度[IC 50] = 2.15 nM)对HT-29,H460和A549细胞系表现出显着的细胞毒性,IC 50值分别为0.10μM,0.13μM和0.05μM,因此效力比福替尼高1.5到2.3倍。他们的初步结构-活性关系(SAR)研究表明,末端苯环上的吸电子基团对于改善抗肿瘤活性是有益的。
