(+)-brazilin BiologicalActivity

Description	Brazilin is a red dye precursor obtained from the heartwood of several species of tropical hardwoods. Brazilin inhibits the cells proliferation, promotes apoptosis, and induces autophagy through the AMPK/mTOR pathway. Brazilin shows chondroprotective and anti-inflammatory activities[1][2][3].
