Abstract

In the last decade, high cariesprophylactic efficacy of ammonium hexafluorosilicates, including salts with substituted biologically active ammonium cations, has been demonstrated. Among the promising anti-caries agents are recently synthesized 2-, 3-, 4-carboxymethylpyridinium hexafluorosilicates, for whose cations anti-inflammatory activity is expected.

The aim of the work is to assess the presence of anti-inflammatory activity in the series of 2-, 3-, 4-carboxymethylpyridinium hexafluorosilicates in the experiment.

2-, 3-, 4-Carboxymethylpyridinium hexafluorosilicates (I–III, respectively) were synthesized according to the previously proposed technique, carrageenan is a commercial preparation, reference drug is a indomethacin. Experiments on the anti-inflammatory activity of hexafluorosilicates were performed on 77 white Wistar male rats weighing 174–190 g using the carrageenan model of inflammation. The inflammatory reaction was reproduced by subplantary administration of 0.1 ml of a 0.2% solution of carrageenan, the studied compounds were administered orally in doses 1/10, 1/20, 1/50 from LD50 for the compound III.

It was established that after administration of carrageenan, animals of the control group showed marked paw edema, which gradually increased and was maximal after 24 hours of observation. According to the data obtained, the indices for compounds I-III practically do not differ from those of the control group. This indicates that, despite the results of the PASS forecast and the presence of acetic acid residue, an anti-inflammatory pharmacofor, in compounds I-III, the compounds under study do not have an anti-inflammatory effect in the carrageenan model.

2-, 3-, 4-Carboxymethylpyridinium hexafluorosilicates do not show the expected anti-inflammatory activity in the carrageenan model of inflammation.
