A new series of compounds containing 4-thiazolidinone pharmacophore 5(a-d) have been synthesized. The chemical structure of the intermediate and final compounds was characterized and confirmed by using FT-IR and 1H-NMR spectroscopy. All final compounds were tested against Gram-positive and Gram-negative bacteria using a well-diffusion technique for their ability as antimicrobial agents. The 5b and...
