Under condition of oxidative stress, free radical mediated peroxidation of polyunsaturated fatty acids generates in vivo, cyclic metabolites like the isoprostanes, neuroprostanes, dihomo-isoprostanes, isofuranes among a large number of key products which participate in many pathophysiological processes. These metabolites display a wide range of biological actions, and some of them are now the most reliable indicators of oxidative stress in humans. In this review, we will discuss several key points of our understanding of those cyclic polyunsaturated fatty acids derivatives, going from multi-step syntheses, analytical chemistry and biological activities.
Résumé
La peroxydation radicalaire des acides gras polyinsaturés, constituants majeurs des membranes cellulaires, conduit à de nombreux métabolites, comme les isoprostanes, les neuroprostanes, les dihomo-isoprostanes, les isofuranes. Certaines isoprostanes sont à présent des marqueurs du stress oxydant cellulaire les plus significatifs utilisés en clinique. Ces lipides oxygénés possèdent également un large spectre d’activités biologiques. Cette revue fera le point sur notre dernière stratégie de synthèse organique multi-étapes pour obtenir ces molécules pures et sur des résultats récents issus de collaborations avec des collègues biologistes et cliniciens.
