title: Antioxidant activity of probucol. Short communication.
abstract: To evaluate a possible antioxidant activity of probucol on NADPH-dependent microsomal lipid peroxidation and on iron-doxorubicin (adriamycin) complex-induced phospholipid peroxidation, the effects were compared with another powerful antioxidant, 2-OH-estrone. Antioxidant activity of 10 mumol/l probucol in NADPH-dependent microsomal lipid peroxidation corresponded to 4 mumol/l 2-OH-estrone. Together with the results obtained from iron-doxorubicin complex-induced phospholipid peroxidation, it was concluded that probucol is a potent inhibitor of lipid peroxidation and has one-quarter to one-half the antioxidant activity of 2-OH-estrone in vitro.
