Betulinic acid (472-15-1) is a natural Lupane triterpenoid from white birch tree (Betula pubescens). Induces apoptosis in a variety of cell lines.¹ Induces mitochondrial permeability transition pore opening.²  Acts as a chemosensitizer for anticancer drug treatment in chemoresistant colon cancer cell lines.³ Cell permeable.
