EFFECT OF AMINOETHYLPYRROLES ON CARRAGEENAN-INDUCED INFLAMMATION AND ON LIPID-PEROXIDATION IN RATS - SOME STRUCTURAL ASPECTS

Nine 3-(2-aminoethyl)pyrrole derivatives were investigated as anti-inflammatory agents in the carrageenan-induced rat paw oedema model and as antioxidants in the non-enzymatic lipid peroxidation assay. It was found that the derivatives which were substituted with a p-toluenesulphonyl group exhibited considerable anti-inflammatory activity and some also showed antioxidant properties. However, the presence of a p-toluenesulphonyl group did not invariably lead to activity. A structural feature which was essential for both activities was the aminoethyl side chain. Although a relationship between the anti-inflammatory and the antioxidant activities was not apparent, the combination of these properties could be useful.
