Pterostilbene

Pterostilbene is a polyketide synthase-derived stilbene originally isolated from P. santalinus that has diverse biological activities. It reduces photooxidative leakage induced by the herbicide acifluorfen in C. sativus cotyledon disks when used at a concentration of 30 µg/ml. Pterostilbene (25 and 50 µM) inhibits invasion and migration of HepG2 hepatoma cells induced by 12-O-tetradecanoylphorbol 13-acetate (TPA, Cay-10008014). It inhibits the production of nitric oxide (NO) and prostaglandin E2 (PGE2, Cay-14010) in LPS-stimulated RAW 264.7 macrophages when used at concentrations of 10 and 20 µM. Pterostilbene (100 and 300 µM) activates peroxisome proliferator-activated receptor alpha (PPARalpha) in H4IIEC3 rat hepatoma cells. It decreases plasma glucose and LDL levels and increases plasma levels of HDL in a hamster model of hypercholesterolemia induced by a high-fat diet when administered in the diet at 25 ppm.Formal Name: 4-[(1E)-2-(3,5-dimethoxyphenyl)ethenyl]-phenol.
