different target inhibitors. In this study, a series of novel indole-2-one derivatives based on 1,2,3-triazole scaffolds were synthesized for the first time, and their inhibitory activity on vascular endothelial growth factor receptor-2 (VEGFR-2) was tested. Most of the compounds had shown promising activity in the VEGFR-2 kinase assay and had low toxicity to human umbilical vein endothelial cells (HUVECs)
在过去的五年中,我们的团队一直致力于点击化学研究,通过合成不同的目标抑制剂来探索1,2,3-三唑的生物活性。本研究首次合成了基于1,2,3-三唑骨架的一系列新型吲哚-2-酮衍生物,并测试了它们对血管内皮生长因子受体2(VEGFR-2)的抑制作用。 。大多数化合物在VEGFR-2激酶测定中显示出有希望的活性,并且对人脐静脉内皮细胞(HUVEC)毒性低。化合物13d(IC 50 = 26.38 nM)具有比舒尼替尼(IC 50)更好的激酶活性抑制能力 = 83.20 nM),对HUVEC的毒性较小。而且,它对HT-29和MKN-45细胞具有优异的抑制作用。一方面,通过试管形成分析,transwell和Western blot分析,化合物13d可以抑制HUVEC上的VEGFR-2蛋白磷酸化,从而抑制HUVEC的迁移和管形成。在体内研究中,带有VEGFR-2标记的斑马鱼模型还证实了化合物13d比
