A triterpene with diverse biological activities
Oleanolic acid acetate is a triterpene that has been found in the root bark of M. macrophylla and has diverse biological activities.1,2,3,4 It is active against P. gingivalis (MIC = 39 ?g/ml).1 Oleanolic acid acetate (5-50 ?M) induces apoptosis in and reduces viability of HCT116 colon carcinoma cells.2 It induces apoptosis in human umbilical vein endothelial cells (HUVECs) in vitro and inhibits capillary vessel formation in a Matrigel? plug assay in mice.3 Oleanolic acid acetate (2, 10, and 50 mg/kg) reduces the number of skin lesions, epidermal thickness and immune cell infiltration, and serum IgE, IgG2a, and histamine levels in a mouse model of atopic dermatitis.4
