Sulfamerazine and sulfaguanidine are clenched with p-nitrobenzoyl chloride and the products obtained are reduced to NaxS in ethanol-water. Novel sulfonamides (6a-g and 9a-g) were synthesized by the reaction of these reduced products (4 and 8) with various sulfonyl chlorides (5a-g). The structures of these compounds were characterized using spectroscopic analysis (IR, H-1-NMR, C-13-NMR and HRMS) technique. Antimicrobial activity of sulfonamides (3, 4, 7, 8, 6a-g and 9a-g) was evaluated by the agar diffusion method. These compounds showed antimicrobial activity against tested microorganism strains (Gram-positive bacteria, clinic isolate and yeast and mold). Compounds 9d, 9e, 9a, 6d and 6e showed particularly antimicrobial activity against tested Gram-positive (Bacillus cereus and B. subtilis) and Gram-negative (Enterobacter aerogenes) bacteria.
