| Outline of Final Research Achievements |
Lipid derived radicals and its metabolic products are closely involved in the pathogenesis of oxidative stress diseases such as inflammation and angiogenesis through the formation of protein or DNA complex. The starting point of lipid peroxide generation is lipid derived radicals which increase explosively via radical chain reaction. Therefore, the trapping of lipid derived radicals is useful to understanding the mechanism of formation of oxidative stress diseases, and to suppress the following chain reaction. On the other hands, nitroxides having stable unpaired electron allows spin trapping with carbon-centered radicals. Hence, in this study, we aimed to develop and evaluate lipid derived detection method using profluorescent nitroxide switching methods.
