Synthesis and biological evaluation of novel β-carboline derivatives as antiproliferative agents
Letters in Drug Design and Discovery（2013）
Abstract
A series of novel β-carboline derivatives was synthesized and evaluated for their cytotoxic activities in vitro against two human tumor cell lines. Most of the compounds showed moderate to potent cytotoxic activities against the tested cell lines, in which compound 12l exhibited the most potent antiproliferative activities against KB cell line (IC50 = 4.58 μM). Preliminary mechanism research on compound 12l indicated that it could inhibit DNA intercalation and tubulin polymerization. ©2013 Bentham Science Publishers.
