Previously [1, 2] we synthesized a series of azolides of aliphatic and aromatic sulfonic acids and studied their immunomodulant and cytoprotector properties. In continuation of that work, we have synthesized a series of new aliphatic and aromatic sulfonic acid azolides and evaluated the products with respect to biological activity. The new series includes 2- benzotriazolide (I) and benzimidazolide (II) of methanesulfonic acid and 1, 2, 4-triazolide ( ...
