against c-Met kinase. The most promising compound 47 (with c-Met IC50 value of 1.57 nM) showed remarkable cytotoxicity against HT-29, H460, A549 and MKN-45 cell lines with IC50 values of 0.08 μM, 0.14 μM, 0.11 μM and 0.031 μM, respectively, and thus it was 1.1- to 2.3- fold more potent than foretinib. Their preliminary structure-activity relationships (SARs) studies indicate that electron-withdrawing groups
合成了一系列含有1,2,4-三唑酮部分的新型4-苯氧基喹啉衍生物,并评估了它们对四种癌细胞系(HT-29,H460,A549和MKN-45)的体外细胞毒活性。大多数化合物表现出中度至显着的细胞毒性。化合物33,37,39,44,46,47,53,55,61,64和66进行了进一步考察了它们的抑制活性对c-Met激酶。最有前途的化合物47(c-Met IC 50值为1.57 nM)对HT-29,H460,A549和MKN-45细胞系表现出显着的细胞毒性,IC 50值分别为0.08μM,0.14μM,0.11μM和0.031μM,因此是1.1- 2.3-倍于福瑞替尼。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。
