In an investigation of the anti-inflammatory properties of five-membered ring nitrogen-containing heterocyclic compounds, two series of derivatives of imidazole were prepared by altering the sites of substitution and by joining aliphatic chains to the nitrogen atom in the 1 position of the imidazole ring. Some of them were more potent inhibitors of carragenan-induced edema than indomethacin. An electron spin resonance study indicated that these compounds possess anti-radical activity.

A series of compounds based on the structure of MTI (1-methyl-2-thioimidazole) were synthesized by condensation of α-hydroxyketones and alkylthioureas. The α-hydroxyketones were obtained by a radical reaction in the presence of sodium and the alkyl ester, while the alkylthioureas were prepared by nucleophilic addition of ammonia on an alkylisothiocyanate. The antithyroid activity of the 13 compounds prepared was evaluated in vitro by determination of the concentrations which led to a 50% inhibition (IC50) of the activity of thyroid peroxidase, and in vivo by assay of thyroid hormones levels and histological examination of the thyroid gland in rats treated chronically with the compounds. 1-methyl-4,5-dipropyl 2-thioimidazole (compound 10) was found to have the highest antithyroid activity of the 13 compounds synthesized.
