NCIt definition : A pentacyclic lupane-type triterpene derivative of betulin (isolated from the bark
of Betula alba, the common white birch) with antiinflammatory, anti-HIV and antineoplastic
activities. Betulinic acid induces apoptosis through induction of changes in mitochondrial
membrane potential, production of reactive oxygen species, and opening of mitochondrial
permeability transition pores, resulting in the release of mitochondrial apogenic
factors, activation of caspases, and DNA fragmentation. Although originally thought
to exhibit specific cytotoxicity against melanoma cells, this agent has been found
to be cytotoxic against non-melanoma tumor cell types including neuroectodermal and
brain tumor cells.;
