Gambogic acid (GA), a naturally occurring xanthone-based moiety, reported from Garcinia hanburyi tree, is known to perform numerous intracellular and extracellular actions, including programmed cell death, autophagy, cell cycle arrest, antiangiogenesis, antimetastatic, and anti-inflammatory activities. In addition, GA-based synergistic approaches have been proven to enhance the healing strength of existing chemotherapeutic agents along with lesser side effects. Among cellular targets of gambogic acid topoisomerase, multidrug-resistant protein ATP-binding cassette transporter B1 (ABCB1) and Transferrin receptor.

Sample Use Guides

In Vivo Use Guide

The animals in the treatment group received one of three dosages of gambogic acid (in saline; 5, 10 or 20 mg/kg) via the caudal vein twice weekly. For intraperitoneal administration the mice were randomly assigned to treatment with 10, 20 or 30 mg/kg gambogic acid for 3 weeks.

Route of Administration: Other

In Vitro Use Guide

Gambogic acid displays potent antiproliferative activity against a wide panel of human tumors without distinct selectivity among the cells lines tested. The average IC50 of GA against the 21 cell lines was 1.23 μmol/L.
