-fluorophenoxy)quinoline derivatives possessing 1,2,3-triazole-4-carboxamide moiety were designed, synthesized and evaluated for their in vitro biological activities against c-Met kinase and five typical cancer cell lines (A549, H460, HT-29, MKN-45 and U87MG). Most compounds showed moderate to excellent antiproliferative activity. In this study, a promising compound 34, with a c-Met IC50 value of 1
设计,合成了一系列具有1,2,3-三唑-4-羧酰胺部分的6,7-二取代-4-(2-氟苯氧基)喹啉衍生物,并评估了其对c-Met激酶和5种化合物的体外生物学活性。典型的癌细胞系(A549,H460,HT-29,MKN-45和U87MG)。大多数化合物显示出中等至优异的抗增殖活性。在这项研究中,c-Met IC 50值为1.04 nM的有前途的化合物34被确定为多靶受体酪氨酸激酶抑制剂。SAR分析表明,在苯环(B部分)的4位带有卤素基团,尤其是氟基团的化合物具有强大的抗肿瘤活性,而5原子接头上的甲基化在c-Met酶促活性中起着重要作用。 。
