Abstract

A synthetic seleno-organic compound, 2-phenyl-1,2-benzoisoselenazol-3(2H)-one (PZ 51), exhibits GSH peroxidase-like activity in vitro, in contrast to its sulfur analog, PZ 25. In addition, PZ 51 behaves as an antioxidant shown by a temporary protection of rat liver microsomes against ascorbate/ ADP-Fe-induced lipid peroxidation, an effect also elicited by PZ 25 but to a smaller extent. This protection against lipid peroxidation is independent of GSH and of P-450 monooxygenase activity.

    Ebselen (2-phenyl-1,2-benzisoselenazol-3(2H)-one) a synthetic seleno-organic drug molecule with anti-inflammatory and antioxidant activities has been investigated as a possible treatment for a range of indications including hearing loss and tinnitus. With a glutathione peroxidase-like activity (Müller et al., 1984), ebselen treatment of rat organ of Corti explants in vitro resulted in protection of hair cells from damage (Kopke et al., 1997). Oral treatment for 7 days post intratympanic injection of gentamicin protected guinea pig organ of Corti from ototoxic effects (Takumida et al., 1999).
