Abstract

Horseradish peroxidase (HRP) inhibition and glutathione peroxidase (GPx) activities of ebselen and some related derivatives are described. These studies show that ebselen and ebselen ditelluride $(EbTe_2)$ with significant antioxidant activity, inhibit the HRP-catalyzed oxidation reactions. In addition, inhibition of lipid peroxidation and singlet oxygen quenching studies were carried out. Although the inhibition of HRP by ebselen is comparable with that of $EbTe_2$, the inhibitory effect on c-radiation induced lipid peroxidation and the GPx activity of ebselen is found to be much higher than that of $EbTe_2$.
