The glutathione peroxidase (GPx) activities of some diaryl diselenides incorporating tertiary amino groups were studied with H(2)O(2), Cum-OOH, and tBuOOH as substrates and with PhSH as thiol co-substrate. Simple replacement of a hydrogen atom with a methoxy group dramatically enhances the GPx activity. The introduction of methoxy substituents ortho to selenium in N,N-dialkylbenzylamine-based compounds

In this work, several tertiary amine-based diaryl diselenides were synthesized and evaluated for their glutathioneperoxidase (GPx)-like antioxidantactivities using hydrogen peroxide, tert-butyl hydroperoxide and cumene hydroperoxide as substrates and thiophenol (PhSH) and glutathione (GSH) as co-substrates. A comparison of the GPx-like activity of 4-methoxy-substituted N,N-dialkylbenzylamine-based
