Cyclic seleninate esters function as mimetics of the antioxidant enzyme glutathione peroxidase and catalyze the reduction of hydrogen peroxide with a stoichiometric thiol. While a single electron-donating methoxy substituent para to the selenium atom enhances the catalyticactivity, m-methoxy groups have little effect and o-methoxy substituents suppress activity. The effects of multiple methoxy groups
