The organoselenium antioxidant 1 was previously found to act as a catalytic antioxidant in a two-phase lipid peroxidation system. In aqueous environment, selenide 1 quenched ABTS-radicals more efficiently than Trolox and ascorbic acid. The selenide dose-dependently scavenged reactive oxygen and nitrogen species more efficiently than Trolox for neutrophils and PMA-stimulated macrophages, with 50% inhibitory concentrations in the low micromolar range. In addition no sign of toxicity or effect on cell viability was seen when culturing five human cell lines in concentrations up to 200 mu M of selenide 1 for up to seven days. We therefore feel that the compound would be a good candidate for future drug development for prevention or treatment of disorders caused by or involving free radical-mediated or oxidative tissue damage.
