摘要:

基于4-苯氧基喹啉类Type II型小分子c-Met激酶抑制剂的结构特点, 设计并合成了13个含缩氨基脲结构的4-苯氧基喹啉类化合物. 采用迁移率改变法(MTS)测试了目标化合物对c-Met激酶的抑制活性. 采用噻唑蓝(MTT)法测试了目标化合物对A549, PC-3, AGS和MKN45细胞的体外抗增殖活性. 体外抗肿瘤活性实验结果表明, 大部分化合物对c-Met激酶和4种肿瘤细胞株均具有较好的抑制活性. 其中化合物6f和6k 具有优秀的抑制c-Met激酶活性[c-Met的半数抑制浓度(IC50)分别为14.50和15.68 nmol/L]. 化合物6f对A549, PC-3, AGS和MKN45细胞的IC50值分别为0.93, 7.81, 12.88和2.58 μmol/L; 化合物6k对A549, PC-3, AGS和MKN45细胞的IC50值分别为0.67, 6.60, 3.04和0.88 μmol/L. 抗肿瘤作用机制研究结果表明, 化合物6k可诱导MKN45和A549细胞发生细胞凋亡, 并能够抑制2种肿瘤细胞的迁移能力.

Abstract:

Thirteen novel 4-phenoxyquinoline derivatives bearing semicarbazone moiety were successfully designed and synthesized based on the structural characteristics of 4-phenoxyquinoline small molecule type II c-Met kinase inhibitors. The in vitro inhibitory activities of all the target compounds against c-Met kinase were evaluated using mobility shift assay. The in vitro antiproliferative activities of the target compounds against A549, PC-3, AGS and MKN45 cells were evaluated using MTT-based assay. Most of the target compounds showed excellent inhibitory activities against c-Met kinase and all the tested cancer cell lines. Among them, compounds 6f(c-Met: IC50=14.50 nmol/L) and 6k(c-Met: IC50=15.68 nmol/L) exhibited excellent inhibition activity of against c-Met kinase. The IC50 values of 6f for A549, PC-3, AGS and MKN-45 cells were 0.93, 7.81, 12.88, and 2.58 μmol/L, respectively. The IC50 values of 6k for A549, PC-3, AGS and MKN45 cells were 0.67, 6.60, 3.04, and 0.88 μmol/L, respectively. Further studies on the anti-tumor mechanism indicated that compound 6k induced MKN45 and A549 cells apoptosis, and inhibited the migration ability of MKN45 and A549 cells.
