A pentacyclic triterpene with diverse bioactivities; inhibits 5-LO (IC50 = ~5 μM); inhibits cell proliferation in HL-60 cells (IC50s = 3.7, 7.1, and 6.3 μM for DNA, RNA, and protein synthesis, respectively); increases nitric oxide and phosphorylation of eNOS in HUVECs deprived of oxygen and glucose; increases calcium mobilization in platelets (≥3 μM); induces platelet aggregation (EC50 = 8 μM),
