About Pterostilbene
Pterostilbene is isolated and identified in blueberries, cranberries, grapes and Dracaena species, it is similar in chemical structure to resveratrol. White crystal; soluble in ethanol, methanol, acetone, ethyl acetate and chloroform, insoluble in water.It's melting point is 87-88,and Molecular formula is C40H56O2 .Recent studies show that pterostilbene has extensive activities such as antifungal(5-fold than that of resveratrol), cancer chempreventive, cancer cell cytotoxic, antioxident, and the most important, cholesterol-lowering(better than ciprofibrate) and anti-diabetic(comparable to metformin) activities. It is now considered to be an agonist of peroxisome proliferator-activated receptor alpha(PPARa). Our group has accomplished the chemical synthesis of pterostilbene and is seeking partners for co-development.
