β-Amyrenonol

β-Amyrenonol (11-Oxo-β-amyrin), an oleanolic-type triterpenoid in licorice roots, is a precursor of Glycyrrhetinic acid. β-Amyrenonol has anti-proliferative and anti-inflammatory activities, and β-Amyrenonol could function as the skeleton for the synthesis of many triterpenoids[1][2].

ChEBI: 11-oxo-beta-amyrin is the pentacyclic triterpenoid that is the 11-oxo derivative of beta-amyrin. It is a pentacyclic triterpenoid and a cyclic terpene ketone. It is functionally related to a beta-amyrin.
