Abstract

A new series of 2-iminothiazolidin-4-ones and thiazolidin-2,4-diones were designed and synthesized. The target compounds were evaluated for antimicrobial and anti-inflammatory activities, aiming to find a candidate carrying dual activities. The antibacterial activity was determined by cup-diffusion technique and NCCLS broth dilution method. The MICs were determined using 96-well microtitre plates, while the anti-inflammatory activity was determined using carrageenan- induced rat paw edema model. The results revealed that target compounds showed no antifungal activity towards tested Fungi, whereas the antibacterial activity was mainly on Gram-positive bacteria. The anti-inflammatory activity was observed in compounds belonging to the thiazolidin-2,4-dione series. The structures of the newly synthesized compounds were confirmed by physical and spectral data.
