Última Antioxidant effect of 4-nerolidylcatechol and α-tocopherol in erythrocyte ghost membranes and phospholipid bilayers BJMBR Fernandes,K.S.; Silva,A.H.M.; Mendanha,S.A.; Rezende,K.R.; Alonso,A.. 4-Nerolidylcatechol (4-NC) is found in Pothomorphe umbellataroot extracts and is reported to have a topical protective effect against UVB radiation-induced skin damage, toxicity in melanoma cell lines, and antimalarial activity. We report a comparative study of the antioxidant activity of 4-NC and α-tocopherol against lipid peroxidation initiated by two free radical-generating systems: 2,2′-azobis(2-aminopropane) hydrochloride (AAPH) and FeSO4/H2O2, in red blood cell ghost membranes and in egg phosphatidylcholine (PC) vesicles. Lipid peroxidation was monitored by membrane fluidity changes assessed by electron paramagnetic resonance spectroscopy of a spin-labeled lipid and by the formation of thiobarbituric acid-reactive substances. When lipoperoxidation... Tipo: Info:eu-repo/semantics/article Palavras-chave: Electron paramagnetic resonance 4-Nerolidylcatechol Spin label Lipid peroxidation DPPH (2; 2-diphenyl-1-picrylhydrazyl).
