Design, synthesis, and biological evaluation of novel N-γ-carboline arylsulfonamides as anticancer agents

Bioorg Med Chem. 2010 Dec 15;18(24):8478-84. doi: 10.1016/j.bmc.2010.10.047. Epub 2010 Oct 25.

Abstract

A series of novel N-γ-carboline arylsulfonamide derivatives designed based on the common feature of colchicine binding site inhibitors were synthesized and evaluated for their antiproliferative activity in vitro against five human cancer cell lines. Most of the compounds showed moderate to potent cytotoxic activities against all the tested cells. Preliminary mechanism research on one of the most potent compound 6p indicated that it was a potent tubulin polymerization inhibitor, with IC(50) value of 3.8 μM, equivalent to that of CA-4, and arresting cell cycle in G(2)/M phase.
