A revised mechanism that accounts for the glutathione peroxidase (GPx)-like catalytic activity of the organoseleniumcompound ebselen is described. It is shown that the reaction of ebselen with H(2)O(2) yields seleninicacid as the only oxidized product. The X-ray crystal structure of the seleninicacid shows that the selenium atom is involved in a noncovalent interaction with the carbonyl oxygen atom
