摘要:
In our previous studies on 1-benzyl-3-(5-hydroxymethyl-2-furyl) indazole (YC-1) analogs, we synthesised numerous substituted carbazole and alpha-carboline derivatives, which exhibited anticancer activity. In this study, we designed and synthesised a series of 3,9-substituted beta-carbolines, by replacing the tricyclic rings of carbazole and alpha-carboline derivatives with isosteric beta-carboline, and evaluated anticancer activity. We observed that 9-(2-methoxybenzyl)-beta-carboline-3-carboxylic acid (11a) inhibited the growth of HL-60 cells by inducing apoptosis, with a half maximal inhibitory concentration of 4.0 mu M. Our findings indicate that b-carboline derivatives can be used as lead compounds for developing novel antitumor agents. (C) 2015 Elsevier Ltd. All rights reserved.
