the toxic effect of such activated mpm was partially inhibited by catalase , superoxide dismutase , cytochrome c , and vitamin e ( alpha-tocopherol ) and was augmented by horseradish peroxidase and the catalase inhibitor aminotriazole ( 3-amino-1h-1,2,4-triazole ) , thus indicating the involvement of oxygen-derived toxic reagents , mainly hydrogen peroxide , in the mpm-mediated damage inflicted on the tumor cells .
