Effect of N-Acetylcysteine on Cu2+(Fe2+)/H2O2-Mediated Free-Radical Fragmentation of Glycerophosphate in the Presence of Biologically Active Compounds

The effect of N -acetylcysteine on homolytic fragmentation of β-glycerophosphate with cleavage of the phosphoester bond has been studied. It has been shown that N -acetylcysteine activates the fragmentation induced by Cu 2+ (Fe 2+ )–H 2 O 2 and inhibits the radiation-induced process. The stimulating...

description The effect of N -acetylcysteine on homolytic fragmentation of β-glycerophosphate with cleavage of the phosphoester bond has been studied. It has been shown that N -acetylcysteine activates the fragmentation induced by Cu 2+ (Fe 2+ )–H 2 O 2 and inhibits the radiation-induced process. The stimulating effect of N -acetylcysteine towards Cu 2+ /H 2 O 2 -mediated fragmentation in the presence of compounds affecting the HO • level, the Cu 2+ /Cu + ratio, or interacting with thiol is either enhanced (Trolox, Ubiquinone Q 0 ) or switched to the protective one (NaN 3 , Met, ascorbate). In the presence of Fe 2+ , Trolox, unlike Q 0 , has reduced the stimulating effect of N -acetylcysteine.
