Product Description:
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.
Pterostilbene is a stilbenoid chemically related to resveratrol. It is thought to be the key compound found predominantly in blueberries (as well as grapes) that exhibit anti-cancer, anti-hypercholesterolemia, anti-hypertriglyceridemia properties, as well as fight off and reverse cognitive decline. It is believed that the compound also has anti-diabetic properties, but so far very little has been studied on this issue. Additionally, it is also touted as a potent anti-fungal.
In plants, it serves a defensive phytoalexin role.It is a type of antioxidant that works by affecting the genes involved in fat metabolism.
