Abstract excerpt
Nitroxide free radicals have been previously shown to function as superoxide dismutase (SOD) mimics and to protect bacterial and mammalian cells against oxidative damage, particularly from superoxide and hydrogen peroxide. Although nitroxides are generally considered to be non-toxic nor mutagenic...
