A series of novel 4-phenoxyquinoline derivatives containing 3-oxo-3,4-dihydro-quinoxaline moiety were synthesized and evaluated for their antiproliferative activity against five human cancer cell lines (A549, H460, HT-29, MKN-45 and U87MG) in vitro. Most of the tested compounds exhibited more potent inhibitory activities than the positive control foretinib. Compound 1b, 1s and 1t were further examined
合成了一系列包含3-oxo-3,4-dihydro-quinoxaline部分的新型4-苯氧基喹啉衍生物,并评估了它们对五种人类癌细胞系(A549,H460,HT-29,MKN-45和U87MG)的抗增殖活性在体外。大多数测试化合物均比阳性对照foretinib表现出更强的抑制活性。进一步检查化合物1b,1s和1t对c-Met激酶的抑制活性。最有前途的化合物1s(c-Met IC 50值为1.42 nM)对具有IC 50的A549,H460,HT-29,MKN45和U87MG细胞系表现出显着的细胞毒性分别为0.39μM,0.18μM,0.38μM,0.81μM。他们的初步结构-活性关系(SARs)研究表明,用环己烷取代芳环可提高其抗增殖活性。
