title: Effect of pineal tetrapeptide on antioxidant defense in Drosophila melanogaster.
abstract: Effects of synthetic pineal tetrapeptide L-Ala-L-Glu-L-Asp-L-Glu (Epithalon) on specific catalase activity and the content of conjugated hydroperoxides in highly inbred Drosophila melanogaster lines differing in reproductive functions were studied. It was shown that Epithalon is a potent modulator of the antioxidant defense, whose biological activity 1000-fold surpasses that of the complex pineal peptide preparation Epithalamin.
