Synthesis and in vitro antimicrobial study of 4-thiazolidinone containing sulfanilamide.

The title compounds, 3-allyl-2-sulfanylamido-4-thiazolidinones (2a-d), have been synthesized after substitution of amino group of sulfanylamide with allylisothiocyanate and cyclization into 4-thiazolidinones. The synthesized compounds were tested for their antibacterial and antifungal activity (MIC) in vitro) against microorganisms: S. aureus, E. faecalis. E. coli, P. aeruginosa, K. pneumoniae, P. mirabilis, B. subtilis, B. cereus and C. albicans taking sulfadimidine, sulfathiazole, sulfanilamide and sulfamethizole as standard drugs. Synthesized compounds (2a-d) demonstrated selective activity against B. cereus.
