Oxidative stress plays an important part in the appearance and development of cardiovascular diseases. In this context, overproduction of reactive oxygen species leads to deregulation of metabolic pathways, such as cell proliferation or inflammation, which interferes with the homeostasis of vascular endothelium. Oxidative stress can decrease the bioavailability of nitric oxide (center dot NO) in vessels. This decrease is highly associated with endothelial dysfunction. The French paradox is a phenomenon that associates a diet rich in saturated fatty acids and a moderate consumption of wine to a low prevalence of cardiovascular diseases. During the past 10 years, the beneficial effects of wine on cardiovascular diseases have been attributed to the actions of resveratrol and other polyphenols. One of the mechanisms involved in these beneficial effects is the capacity of resveratrol and some other stilbene derivatives to maintain sufficient center dot NO bioavailability in vascular endothelium. This review presents the latest findings on the molecular effects of resveratrol and other stilbene derivatives on the various actors that modulate center dot NO bioavailability during oxidative stress.
