[Effect of aminazin on the enzymatic oxidation of lipids].

An inhibitory effect of chlorpromazine on the enzymatic NADPH-dependent lipid peroxidation in rat liver microsomal fraction was found. This inhibition was caused by the 1) antioxidative effect of hydroxy-derivatives appearing during the oxidative metabolism of chlorpromazine with NADPH-dependent microsomal oxygenases, and by the 2) competition for reduced components of electron-carriers between the NADPH-dependent processes: chlorpromazine metabolism and lipids peroxidation.
