  [4-(Chloro-difluoro-methoxy)-phenyl]-{5-[4-((E)-2-pyridin-4-yl-vinyl)-pyridin-3-yl]-[1,3,4]oxadiazol-2-yl}-amine 在 palladium on activated charcoal 氢气 作用下， 以 乙酸乙酯 为溶剂， 反应 4.0h， 生成 N-[4-(chlorodifluoromethoxy)phenyl]-5-{4-[2-(pyridin-4-yl)ethyl]pyridin-3-yl}-1,3,4-oxadiazol-2-amine

  名称：

  Inhibitors of VEGF receptors-1 and -2 based on the 2-((pyridin-4-yl)ethyl)pyridine template

  摘要：

  We have developed a series of novel potent ((pyridin-4-yl)ethyl)pyridine derivatives active against kinases VEGFR-1 and -2. Both specific and dual ATP-competitive inhibitors of VEGFR-2 were identified. Kinase selectivity could be controlled by varying the arylamino substituent at the 1,3,4-oxadiazole ring. The most specific molecules displayed >10-fold selectivity for VEGFR-2 over VEGFR-1. Compound activities in vitro and in cell-based assays (IC50 < 100 nM) were similar to those of reported clinical and development candidates, including PTK787 (Vatalanib(TM)). High permeability of active compounds across the Caco-2 cell monolayer (>30 x 10(-5) cm/min) is indicative of their potential for intestinal absorption upon oral administration.
