• The hepatoprotective activity of 8,8-dimethyl-5- p -tolyl-3,4,7,8-tetrahydro-2 H -pyrido[4,3,2- de ]cinnolin-3-one was studied in vivo using a model of CCl 4 -induced acute toxic hepatitis. It was found that this compound affected indices determining the level of free-radical oxidation, i.e., levels of malondialdehyde (MDA) and diene conjugates (DC), and the activities of the key antioxidant enzymes superoxide dismutase (SOD) and catalase. Hepatoprotective activity was analyzed using the activity levels of the enzymes alanine aminotransferase (AlAT), aspartate aminotransferase (AsAT), and alkaline phosphatase and the bilirubin level. The mechanism of the antioxidant activity was determined from the effect of this compound on the expression levels of the gene katG encoding catalase-hydroperoxidase I and the gene sodA encoding Mn-superoxide dismutase. It was found that 8,8-dimethyl-5- p -tolyl-3,4,7,8-tetrahydro-2 H -pyrido[4,3,2- de ]-cinnolin-3-one exhibited antioxidant activity by increasing the SOD and catalase levels.
