We have synthesized and evaluated a series of novel alkyl diamine linked bivalent beta-carbolines as potent angiogenesis inhibitors. The results demonstrated that most bivalent beta-carbolines exhibited significant antiproliferative effects against human umbilical vein cell lines EA.HY926. Compound 4m was found to be the most potent antiproliferative agent with IC50 value of 2.16 mu M against EA.HY926 cell lines. Mechanism investigations revealed that compound 4m could significantly inhibit EA.HY926 cells migration and tube formation in a dose-dependent manner. Moreover, compound 4m also showed obvious angiogenesis inhibitory effects in CAM assay, and the antiangiogenetic potency was more potent than the reference drug Endostar. The bivalent beta-carbolines might be served as candidates for the development of vascular targeting antitumor drugs. (C) 2016 Elsevier Masson SAS. All rights reserved.
