摘要:
Resveratrol, a stilbenoid antioxidant found in grapes, wine, peanuts and other berries, has been reported to have hypolipidemic properties. Resveratrol and its three analogs (pterostilbene, piceatannol and resveratrol trimethyl ether) were evaluated for their effects on the activation of the peroxisome proliferator-activated receptor alpha (PPARα) isoforms, a receptor shown to mediate the activity of lipid-lowering drugs such as the fibrates. The four stilbenes and ciprofibrate (positive control) were evaluated for the activation of endogenous PPARα in H4IIEC3 cells. Pterostilbene demonstrated the highest induction of PPARα demonstrating increases of 7- and 9-14 fold relative to control. The maximal responses to pterostilbene are similar to those obtained with the hypolipidemic drug, ciprofibrate that is, pterostilbene acts as a PPARα agonist, like that of the fibrate class, and is a more effective hypolipidemic agent than resveratrol.
