Peroxyl - Radical Reaction of RetinylAcetatein Solution
نویسندگان
چکیده
Retinyl acetate suppressed the free radical-induced oxidation of methyl linoleate. Retinyl acetate was reacted with an alkylperoxyl radical in two solvent systems, methanol and benzene, The alkylperoxyl radical was generated by the thermal decompositien of a free radical initiator, 2 2'-azobis(2,4-dimethylyaleronitrile), at 370C. The reaction products were isolated by HPLC and their structures were identified. The main product in methanol was 14-hydroxy-13-methexyretinyl acetate in addition to some minor products. The reaction in benzene gaye some products with low yields. They were 5,6-epoxyretinyl acetate, 11,14epoxyretinyl acetate, and 5,6,11,14-diepoxyretinyl acetate. The results indicate that retinyl acetate is capable of scayenging peroxyl radicals by its coajugated polyene structure.

Theoretical study on the peroxyl radicals scavenging activity of esculetin and its regeneration in aqueous solution.
The study of the ˙OOH, ˙OOCH3 and ˙OOCHCH2 radicals scavenging processes by esculetin (ES) was carried out in aqueous and lipid media, using the density functional theory. Three reaction mechanisms were considered: single electron transfer (SET), hydrogen transfer (HT) and radical adduct formation (RAF). Rate constants and branching ratios for the different paths are reported. It was found that...

We have described a modified method for evaluating inhibitor of peroxyl radicals, a well-recognized and -documented radical involved in cancer initiation and promotion as well as diseases related to oxidative stress and ageing. We are reporting hydrophilic and lipophilic as well as natural and synthetic forms of antioxidants revealing a diversified behaviour to peroxyl radical in a dose-depende...
متن کاملOn the direct scavenging activity of melatonin towards hydroxyl and a series of peroxyl radicals.
The reactions of melatonin (MLT) with hydroxyl and several peroxyl radicals have been studied using the Density Functional Theory, specifically the M05-2X functional. Five mechanisms of reaction have been considered: radical adduct formation (RAF), Hydrogen atom transfer (HAT), single electron transfer (SET), sequential electron proton transfer (SEPT) and proton coupled electron transfer (PCET)...
متن کاملDetection of peroxyl and alkoxyl radicals produced by reaction of hydroperoxides with rat liver microsomal fractions.
E.s.r. spin trapping using the spin trap 5,5-dimethyl-1-pyrroline N-oxide (DMPO) was used to detect peroxyl, alkoxyl and carbon-centred radicals produced by reaction of t-butyl hydroperoxide (tBuOOH) with rat liver microsomal fraction. The similarity of the hyperfine coupling constants of the peroxyl and alkoxyl radical adducts to those obtained previously with isolated enzymes suggests that th...
