Novel benzimidazoles, benzothiazoles and benzofurans incorporating pyrazole moiety have been synthesized and screened for their antiangogenic activities, by testing their ability to inhibit human umbilical vein endothelial cell (HUVEC) proliferation, cord formation and migration in response to chemoattractant. 3 compounds 19, 23 and 26 showed antiangiogenic activities at non-cytotoxic concentrations. Compound 19 was the most active with chemotaxis activity data nearly comparable to that of the positive control, TNP-470. Compound 42 showed a significant cytotoxic effect on the tested cancer cell lines and less antiangiogenesis activity compared to compounds 19, 23 and 26. All the tested compounds, in contrary to TNP-470, interfered with the migratory function of HUVECs in response to vascular endothelial growth factor rather than the endothelial cells proliferation or cord formation. Moreover, a docked pose of compounds 19 and 26 was obtained bound to kinase insert domain receptor using Molecular Operating Environment module.
合成了一些新型苯并咪唑、苯并噻唑和苯并呋喃化合物,并将其与吡唑基团结合,筛选其抗血管生成活性,通过测试它们抑制人脐静脉内皮细胞(HUVEC)增殖、管道形成和对趋化因子的迁移能力。三个化合物19、23和26在非细胞毒浓度下显示出抗血管生成活性。化合物19的活性最强,其趋化活性数据几乎可与阳性对照TNP-470相媲美。化合物42对测试的癌细胞系表现出显著的细胞毒性作用,但与化合物19、23和26相比,其抗血管生成活性较低。所有测试化合物与TNP-470相反,干扰了HUVEC对血管内皮生长因子的迁移功能,而不是内皮细胞的增殖或管道形成。此外,使用分子操作环境模块获得了化合物19和26与激酶插入域受体结合的对接构象。
