A series of novel 4-phenoxyquinoline derivatives containing 3-oxo-3,4-dihydroquinoxaline moiety were synthesized and evaluated for their c-Met kinase inhibitory activity and antiproliferative activity against five cancer cell lines (HT-29, H460, A549, MKN-45 and U87MG) in vitro. Most of the compounds exhibited moderate-to-significant cytotoxicity as compared with foretinib. The most promising compound
合成了一系列包含3-oxo-3,4-dihydroquinoxaline部分的新颖的4-phenoxyquinoline衍生物,并评估了它们对5种癌细胞系(HT-29,H460,A549,MKN- 45和U87MG)体外。与福替尼相比,大多数化合物表现出中度至显着的细胞毒性。最有前途的化合物41(c-Met IC 50值为0.90 nM)对具有IC 50的HT-29,H460,A549,MKN-45和U87MG细胞系表现出显着的细胞毒性分别为0.06μM,0.05μM,0.18μM,0.023μM和0.66μM,因此其效力比福替尼大1.22至3.50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有助于改善抗肿瘤活性。
