Kinase insert Domain-containing Receptor (KDR) is one of the currently validated targets for anticancer drug discovery and development. Herein, a series of o-amino-arylurea derivatives have been synthesized and evaluated for their kinase inhibitory activity. The optimization on the basis of biological screening and molecular modeling resulted in obvious increase in KDR kinase inhibitory activity compared
激酶插入物含域受体(KDR)是抗癌药物发现和开发的当前验证目标之一。在此,已经合成了一系列邻氨基-芳基脲衍生物,并评估了它们的激酶抑制活性。在生物学筛选和分子建模的基础上进行优化,与该命中化合物相比,可明显提高KDR激酶的抑制活性。最终,我们确定了针对KDR的1-(4-氯-3-(三氟甲基)苯基)-3-(2-((喹啉-4-基甲基)氨基)吡啶-3-基)脲支架的有效抑制剂5a( IC 50 = 0.0689 µM),可以作为进一步优化KDR抑制剂和开发的良好起点。
