Definition
Betulinic acid is a pentacyclic triterpenoid that is lupane having a double bond at position 20(29) as well as 3beta-hydroxy and 28-carboxy substituents. It is found in the bark and other plant parts of several species of plants including Syzygium claviflorum. It exhibits anti-HIV, antimalarial, antineoplastic and anti-inflammatory properties. It has a role as an antineoplastic agent, an antimalarial, an EC 5.99.1.3 [DNA topoisomerase (ATP-hydrolysing)] inhibitor, an anti-HIV agent, an anti-inflammatory agent and a plant metabolite. It is a pentacyclic triterpenoid and a hydroxy monocarboxylic acid. It derives from a hydride of a lupane.
