A series of novel alkyl diamine linked bivalent beta-carbolines was synthesized and evaluated for antiproliferative activity, inhibition of cell migration and tube formation, and anti-angiogenic activity in vivo. The results showed that most bivalent beta-carbolines displayed significant antiproliferative effect against human umbilical vein cell lines EA.HY926. Compound 2s was found to be the most potent antiproliferative agent with IC50 value of 1.06 mu M against EA.HY926 cell lines. Further investigations on mechanisms of action revealed that compound 2s significantly inhibited EA.HY926 cells migration and tube formation in a dose-dependent manner. Moreover compound 2s exhibited significant angiogenesis inhibitory effects in CAM assay, and the antiangiogenetic potency was comparable with the reference drug Endostar (30 mu M).

Synthesis of novel β-carbolines with efficient DNA-binding capacity and potent cytotoxicity
A series of water-soluble beta-carbolines, bearing a flexible amino side chain, was prepared and evaluated in vitro against a panel of human tumor cell lines. The N-9-arylated alkyl substituted beta-carbolines represented the most interesting cytotoxic activities, and compound 7b was found to be the most potent antitumor agent with IC50 values lower than 10 mu M against eight human tumor cell lines. The results confirmed that the N-9-arylated alkyl substituents of beta-carboline nucleus played an important role in the modulation of the cytotoxic potencies. In addition, these compounds were found to exhibit significant DNA-binding affinity. (c) 2010 Published by Elsevier Ltd.
