The antioxidant properties of Ergothioneine appear to be related to at least four molecular activities: the ability to scavenge free radicals; to chelate, or combine with, various divalent metallic cations (positively charged ions); to activate antioxidant enzymes such as glutathione peroxidase (Se-GPx) and MnSOD and to inhibit superoxide-generating enzymes such as NADPH-Cytochrome c reductase; and to affect the oxidation of various hemoproteins such as hemoglobin and myoglobin.
