ChEBI: Betulone is a triterpenoid. It has a role as a metabolite. It derives from a hydride of a lupane.

3-Oxobetulin is a pentacyclic triterpenoid and derivative of betulinic acid that has been found in I. macropoda and has diverse biological activities.1,2,3 It is active against the plant pathogenic fungi L. betulina and L. sulphureus when used at a concentration of 30 μg/ml.2 3-Oxobetulin reduces HIV-1 replication in MT-2 cells (IC50 = 4.1 μM) with a 50% cytotoxic concentration (CC50) value of greater than 100 μM.4 It inhibits cadmium-induced cytotoxicity in HepG2 cells in a concentration-dependent manner.3
