Research Abstract |
Peroxynitrite, the reaction product of superoxide and nitric oxide, is a powerful oxidant in vivo. Peroxynitrite is known to induce DNA strand scission, protein modification by nitration and hydroxylation and lipid peroxydation in LDL. The in vitro reactivity of lutein, capsanthin and fucoxanthin toward peroxynitrite was investigated, and the reaction products produced by scavenging with peroxynitrite were analyzed. Nitro-carotenoids were isolated from the reaction of these carotenoids with peroxynitrite. These carotenoids inhibited the nitoration of tyrosin by peroxynitrite.
