angiogenesis inhibitors with potency of promoting vascular normalization. Herein, we reported the design, synthesis and preliminary evaluation of proteolysis-targeting chimera (PROTACs) based on the previously developed anti-angiogenesis agents. Two PROTACs exhibited potent VEGFR-2 inhibition and anti-proliferative activity against HUVECs. Moreover, they were capable of reducing protein levels of VEGFR-2 in EA
我们最近的研究集中在抗血管生成剂的发现上。由抗血管生成剂引起的血管正常化似乎是一种有前途的策略。我们已经开发了具有促进血管正常化能力的新型血管生成抑制剂。在这里,我们报道了基于先前开发的抗血管生成剂的靶向蛋白水解嵌合体(PROTAC)的设计,合成和初步评估。两种PROTAC对HUVEC表现出有效的VEGFR-2抑制作用和抗增殖活性。此外,它们能够降低EA.hy926细胞中VEGFR-2的蛋白水平,而对HEK293细胞没有明显的细胞毒性。新型PROTAC可用于使异常血管正常化,从而有效地输送药物。
