Effects of 5-Pyrimidinol Derivative SNK-41 on Cytokine Profile of Mice with Lewis Lung Carcinoma

Аннотация

We studied the effects of SNK-411, a new 5-pyrimidinol derivative, on serum cytokine profile of C57Bl/6 mice with Lewis lung carcinoma. The compound was injected intraperitoneally in doses of 25 and 50 mg/kg. A significant (by 3.5 times) increase in serum IL-4 content was detected in mice with tumors on day 9 of tumor development. In mice receiving SNK-411 in doses of 25 and 50 mg/kg, IL-4 content significantly decreased (by 4.0 and 3.6 times) on days 2–8 of carcinoma development; IL-2 content decreased by 1.4 and 1.2 times and IL-6 content decreased by 2.7 and 1.6 times, respectively, in comparison with control mice with tumors. Injections of SNK-411 in the same doses on days 8–15 of carcinoma development led to a significant decrease in IL-4 levels (by 2.2 and 4.5 times, respectively, in comparison with control mice with tumors) and did not affect serum levels of other cytokines.
