Popis: | In our continued focus on 1-benzyl-3-(5-hydroxymethyl-2-furyl)indazole (YC-1) analogs, we synthesized a novel series of 3,9-substituted α-carboline derivatives and evaluated the new compounds for antiproliferactive effects. Structure activity relationships revealed that a COOCH3 or CH2OH group at position-3 and substituted benzyl group at position-9 of the α-carboline nucleus were crucial for maximal activity. The most active compound, 11, showed high levels of cytotoxicity against HL-60, COLO 205, Hep 3B, and H460 cells with IC50 values of 0.3, 0.49, 0.7, and 0.8 μM, respectively. The effect of compound 11 on the cell cycle distribution demonstrated G2/M arrest in COLO 205 cells. Furthermore, mechanistic studies indicated that compound 11 induced apoptosis by activating death receptor and mitochondria dependent apoptotic signaling pathways in COLO 205 cells. The new 3,9-substituted α-carboline derivatives exhibited excellent anti-proliferative activities, and compound 11 can be used as a promising pro-apoptotic agent for future development of new antitumor agents. |
