this study, a novel series of 4,6,7-trisubstituted quinoline analogues bearing thiazolidinones were designed and synthesized based on our previous study. Among them, the most potent compound 15i, 4-((4-(4-(3-(2-(2,6-difluorophenyl)-4-oxothiazolidin-3-yl)ureido)-2-fluorophenoxy)-6-methoxyquinolin-7-yl)oxy)-N,N-diethylpiperidine-1-carboxamide was identified as a multi-kinase inhibitor.

在这项研究中,基于我们之前的研究,设计并合成了一系列带有
噻唑烷酮的新型 4,6,7-三取代
喹啉类似物。其中,效力最强的化合物15i,4-((4-(4-(3-(2-(2,6-二
氟苯基)-4-oxothiazolidin-3-yl)ureido)-2-fluorophenoxy)-
6-甲氧基喹啉-7-基)氧基) -N,N-二乙基
哌啶-1-甲酰胺被鉴定为多激酶
