چکیده انگلیسی
The in vitro reactivities of astaxanthin and β-carotene toward peroxynitrite were investigated and the reaction products after scavenging with peroxynitrite were analyzed. A series of carotenoids substituted with nitro group, 14â²-s-cis-15â²-nitroastaxanthin, 10â²-s-cis-11â²-cis-11â²-nitroastaxanthin, 14â²-s-cis-15â²-nitro-β-carotene and 10â²-s-cis-11â²-cis-11â²-nitro-β-carotene, were isolated from the reaction products of carotenoids with peroxynitrite. Carotenoids with nitro derivatives were reported for the first time. These results indicated that astaxanthin and β-carotene could catch peroxynitrite or nitrogen dioxide radical (NO2) in their molecule to form nitrocarotenoids.
