Thiazole derivatives were shown to have toxic effects in vitro on cancer cells of different origin and can be considered as potentially antineoplastic, but their effect on the normal tissues needs to be studied. In this research the newly synthesized thiazole derivatives of N-(5-benzyl-1,3-thiazol-2-yl)-3,5-dimethyl-1-benzo-furan-2-carboxamide (BF1) and 8-methyl-2-Me-7-[trifluoromethyl-phenylmethyl]-pyrazolo [4,3-e] [1,3] thiazolo [3,2-a] pyrimidin-4 (2H)-one (PP2) were used and their effect on the pro- and antioxidant processes after adding in a 1, 10 and 50 μM concentrations to the liver homogenate of healthy and NK/Ly lymphoma-bearing mice was estimated. The level of superoxide radical and TBA-active products as well as catalase, SOD and glutathione peroxidase activity were measured. It was shown that superoxide radical and TBA-active products­ level and catalase activity were significantly higher in the liver of tumor-bearing mice than in the liver of the healthy mice. Neither BF1 no PP2 influenced the studied indices in the liver homogenate of healthy and tumor-bearing animals with the exception that PP2 significantly reduced the level of TBA-positive products in both cases. The data obtained showed that the studied thiazole derivatives did not cause severe liver toxicity in both healthy and tumor-bearing mice.
