Biological Activity

Description Gambogic Acid (Guttatic Acid, Guttic Acid, Beta-Guttiferrin) activates caspases with EC50 of 0.78-1.64 μM and competitively inhibits Bcl-XL, Bcl-2, Bcl-W, Bcl-B, Bfl-1 and Mcl-1 with IC50 of 1.47, 1.21, 2.02, 0.66, 1.06 and 0.79 μM, respectively.

In vitro Gambogic Acid is a caged xanthone that is derived from Garcinia hanburyi and functions as a strong apoptotic inducer in many types of cancer cells by inhibiting human Bcl-2 family proteins and activating caspases. Gambogic Acid also blocks Kir2.1 channels with EC50 of ≤ 100 nM.[1] [2] [3] Gambogic Acid significantly inhibits human umbilical vein endothelial cell (HUVEC) proliferation, migration, invasion, tube formation, and micro-vessel growth at nM concentration. [4]
In vivo Gambogic Acid effectively inhibits tumor angiogenesis and suppressed tumor growth with low side effects using metronomic chemotherapy with Gambogic Acid. [4] Gambogic Acid has multiple functional effects including the induction of apoptosis, the inhibition of proliferation and the prevention of cancer metastasis and tumor angiogenesis. [5] In both animal tumor models and clinical trials, Gambogic Acid efficiently inhibits tumor growth with minimal side effects, with little toxicity on immune and hemopoietic systems. Gambogic Acid can produce tissue-specific proteasome inhibition and tumor-specific toxicity. [6] LD50: Mice 45mg/kg (i.p.). [7]
