[Antioxidant activity of condensed [1,2,4]-triazinone derivatives in nitrosative stress].

Antioxidant activity of nine [1,2,4]-triazinone derivatives was studied in the work. Our data show that [1,2,4]-triazinone derivatives with benzyl alcohol, propyl alcohol, me-thyl alcohol and tolyl residues in their structure have antioxidant activity in condition of in vitro NO formation. KO-17 compound proved to have the greatest antioxidant activity which exceeded N-acetyl cysteine's one.
