A series of novel 4-(2-fluorophenoxy)quinoline derivatives containing 4-oxo-1,4-dihydrocinnoline-3-carboxamide moiety were designed, synthesized and evaluated for their in vitro biological activities against c-Met kinase and six typical cancer cell lines (A549, H460, HT-29, MKN-45, U87MG and SMMC-7721). All the prepared compounds showed moderate to excellent antiproliferative activity, and the analysis
设计,合成并评估了一系列含有4-oxo-1,4-dihydrocinnoline-3-carboxamide部分的新型4-(2-氟苯氧基)喹啉衍生物,它们对c-Met激酶和六种典型癌细胞的体外生物学活性线(A549,H460,HT-29,MKN-45,U87MG和SMMC-7721)。所有制备的化合物均显示出中度至优异的抗增殖活性,对它们的结构-活性关系的分析表明,在肉桂酸环1位上的2-氯或2-三氟甲基取代的苯基更有利于抗肿瘤活性。在这项研究中,c-Met IC 50值为0.59 nM的有前途的化合物33被鉴定为多靶受体酪氨酸激酶抑制剂。
