Novel maleimide derivative 1-(4-Cl-benzyl)-3-Cl-4-(CF3-phenylamino)-1H-pyrrol-2.5-dione (MI-1) with cytostatic activity does not damage rat liver cells after intragastric administration. It is confirmed by alanine- and aspartate aminotransferase, lactate dehydrogenase and alkaline phosphatase activities in blood serum. Preliminary treatment with MI-1 partially prevents from liver cell damage caused by CoCl2. the content of thiobarbituric-active products, protein carbonyl groups, reduced glutathione and activities of superoxide dismutase, catalase, glutathione peroxidase and glutathione-S-transferase in the liver cell after one- and ten-days treatment with novel maleimide derivative have been studied. It has been determined that one-day administration of MI-1 has not caused significant changes of peroxidation process and antioxidant system in the liver cells. After ten days treatment the activity of glutathione-S-transferase has been increased, superoxide dismutase?– two times decreased, but other parameters have not been significantly changed. Ten days injection of CoCl2 provokes some manifestations of oxidative stress in the liver cells that has been partially leveled by preliminary treatment with maleimide derivative.
Key words: maleimide derivative, aminotransferase, peroxidation, antioxidant system, CoCl2.
