摘要：

Isoprostanes are a new class of lipids, isomers of conventional enzymatically derived prostaglandins, which are produced in vivo primarily by a free radical-catalyzed peroxidation of polyunsaturated fatty acids. F-2-isoprostanes, isomers of the enzyme-derived prostaglandin F-2alpha, are the most studied species. Because of their mechanisms of formation, specific structural features that distinguish them from other free radical-generated products and chemical stability, they provide a reliable index of the oxidative component of several diseases in vivo. Consistent data suggest that formation of F-2-isoprostanes is indeed altered in a variety of clinical settings associated with inflammation and oxidant stress. Moreover, measurement of F-2-isoprostanes might provide a sensitive biochemical basis of dose-selection in studies of natural and synthetic antioxidants. (C) 2003 Elsevier Ireland Ltd.
