Isolated from the leaves of Syzygium claviflorum, it exhibits anti-HIV and antileishmanial activity. It has a role as a metabolite, an anti-HIV agent, an antileishmanial agent, an EC 5.99.1.2 (DNA topoisomerase) inhibitor and an EC 5.99.1.3 [DNA topoisomerase (ATP-hydrolysing)] inhibitor. It is a hydroxy monocarboxylic acid and a pentacyclic triterpenoid. It derives from a hydride of a lupane."}]
