Abstract
Objective. To study the anti-inflammatory activity and some toxicological indicators of the new derivative of pyrazole-3-carboxamide SSP.
Materials and methods. To assess the biological activity of the compound, its anti-inflammatory effect was studied in the model of acute inflammatory edema caused by sub-plantar injection of carrageenan solution into a rat`s hind leg. The duration effect was assessed by the intensity of suppression of the inflammatory response in relation to the control level. In order to study the safety of the substance, the local irritant effect was determined when applied cutaneously in the experiments on rats. The severity of the irritant effect was assessed by the erythema degree, the amount of edema and the increase in local skin temperature. In addition, acute toxicity of the substance under study was determined. The test compound and reference drugs were applied to the skin.
Results. The study of acute toxicity of the compound SSP and the reference drug nystatin when applied cutaneously to rats showed that LD50 of both substances was more than 2500,0 mg/kg. Indicators of the degree of local irritating effect of the drugs demonstrate its absence. At the same time, the studied SSP compound has no anti-inflammatory effect administered either orally or cutaneously.
Conclusions. The data obtained allow us to classify the new silver salt of pyrazol-3-carboxamide SSP as a class 5 non-toxic substance. The studied SSP compound has no local irritant effect and does not demonstrate anti-inflammatory activity in the carrageenan inflammation model.
