Gambogenic Acid (GNA) 是从藤黄中分离出来的聚异戊二烯化氧杂蒽酮。

Gambogenic acid (GNA) is a polyprenylated xanthone isolated from gamboge, shows potent antitumor activity and can effectively inhibit the survival and proliferation of cancer cells; specifically and covalently binds to Cys668 within the EZH2-SET domain, trigges EZH2 degradation (IC50=8.6 uM) through COOH terminus of Hsp70-interacting protein (CHIP)-mediated ubiquitination; synergistically potentiates bortezomib-induced apoptosis in multiple myeloma; also induces proteasomal degradation of CIP2A and sensitizes hepatocellular carcinoma to anticancer agents.

Western Blot Analysis Cell Line:SCLC cell lines (NCI-H446/NCI-H1688) Concentration:1.1-1.3 μM for NCI-H446 cells, 2-2.3 μM for NCI-H1688 cells Incubation Time:24 h Result:Increased the expression of cleaved caspase-3, -8 and -9, Bax, cleaved PARP and p53 proteins.

Animal Model:SCLC mouse xenograft modelDosage:4-12 mg/kg Administration:i.v., every 2 days, 14 days Result:Increased the expression of pro-apoptotic proteins (cleaved caspase-3, -8 and -9, Bax, cleaved PARP and p53 proteins).Decreased the anti-apoptotic proteins (Bcl-2).
