A sesquiterpene with diverse biological activities
Isocurcumenol is a sesquiterpene that has been found in C. zedoaria rhizomes and has diverse biological activities.1,2,3 It inhibits mycelial growth of the plant pathogenic fungus F. graminearum when used at a concentration of 0.5 mg/ml.1 Isocurcumenol is cytotoxic to DLA, A549, KB, and K562 cancer cells (IC50s = 75.3, 75.7, 142.2, and 45.83 µg/ml, respectively).2 It inhibits LPS-induced production of nitric oxide (NO) in isolated mouse peritoneal macrophages.3 Isocurcumenol (50 mg/kg) reduces LPS/D-galactosamine-induced increases in serum levels of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) in a mouse model of liver injury.
