Triterpenoid. Antitumor agent. Induces caspase-dependent apoptosis by inhibiting the chymotrypsin-like activity of the proteasome. Inhibits NF-κB activation via inhibition of IKKα or IKKβ. Inhibits induction of inducible nitric oxide synthase (iNOS; NOS II). Shows in vitro antimalarial and insecticidal activity. Induces mitochondrial cell death. Has antiproliferative, antifungal and antiviral properties. Potent and reversible monoacylglycerol lipase (MGL) inhibitor.
