Trolox has shown to protect mammalian cells from oxidative damage. Trolox is effective in preventing myocyte necrosis in cell culture studies and in a canine model of two hours of left anterior descending coronary artery (LAD) occlusion followed by four hours of reperfusion. Trolox could prevent oxidative stress-induced apoptosis in thymocytes. Pre- or posttreatment of cells with Trolox reduced H 2 O 2 -induced DNA fragmentation to control levels and below. . Trolox is a hydrophilic analogue of alpha-tocopherol and reported to scavenge peroxyl radicals better than vitamin E in sodium dodecyl sulfate micelles and in liposomes. Trolox prolongs substantially the survival of human ventricular myocytes and hepatocyte against oxyradicals generated with xanthine oxidase plus hypoxanthine, and prevented lysis of red cells exposed to an azo-initiator.
