Trolox is an analogue of vitamin E with a powerful antioxidant effect. Trolox is also a powerful inhibitor of membrane damage.
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[1]. Trolox could prevent oxidative stress-induced apoptosis in thymocytes. Pre- or post-treatment of cells with Trolox reduced H2O2-induced DNA fragmentation to control levels and below. [2]. Trolox is a hydrophilic analog 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[3].
Thymocytes are treated with Trolox (10 mM) before, during, or after 10 min exposure to 10 μM H2O2. Trolox incubations that are conducted before or after H2O2 exposures are performed in TCM. Trolox treatments that are administered concurrently with H2O2 are performed in PBS with ferrous sulfate[1].
