]thiazolidine-2,4-dione–[1,2,3]triazolehybrid derivatives were synthesized by click chemistry reaction and screened for antimicrobial activity against Gram positive and Gram negative bacteria and fungal species. All synthesized compounds were characterized by 1H and 13C NMR, IR and MS spectra. Antibacterial study indicated that several products demonstrated high activity and some products were determined

Structural exploration, synthesis and pharmacological evaluation of novel 5-benzylidenethiazolidine-2,4-dione derivatives as iNOS inhibitors against inflammatory diseases
In our previous work, 3I inhibited the LPS-induced iNOS activity and NO production in RAW 264.7 cells and improved joint inflammation and cartilage destruction in inflammatory model. In this study, we synthesized 59 derivatives and bioisosteres on the basis of 3I by Knoevenagel condensation and biologically evaluated for the study of structure-activity relationship (SAR). We found that 7-44 suppressed the iNOS activity (IC50 25.2 mu M) and LPS-induced NO production (IC50 45.6 mu M) in RAW 264.7 cells. As for the SAR study, the dimethoxylphenyl group of 7-44 was potential for a further modification. At a dose of 10 mg/kg, oral administration of 7-44 possessed protective properties in both carrageenan-induced paw edema of male ICR mice and adjuvant-induced arthritis of Lewis female rats. Although the activity of 7-44 was slightly inferior, the PK profiles of 7-44 were superior to those of 3I. (C) 2014 Elsevier Masson SAS. All rights reserved.
