“…Considering the advances in recent decades, especially in the science of synthesis of pharmaceutical structures, it seems the main strategy against microbial resistance is to develop new drug structures. Nowadays, S-triazole core is considered as a significant moiety in the design and synthesis of bioactive compounds possessing many biological properties, including anti-microbial [4][5] , antibacterial [6] , antifungal [7] , anti-HIV [8] , anti-inflammatory [9] , analgesic [10] and anticancer activities [11] . Fungal and bacterial infections have become a major challenge and an important cause of fatality.…”

Backgrounds: Nowadays, the need for replacement of new drug structures is felt more than ever due to the spread of microbial resistance. S-triazoles are significant five-membered heterocyclic scaffolds due to their wide range of biological activities. Materials & Methods:A new series of Schiff bases (5a-f) were synthesized by the reaction of 4-amino-S-triazoles (3a-c) with furan and benzaldehyde 4(d-e). Then a novel series of triazole thioglycosides (7a-f) were synthesized by the reaction of Schiff bases (5a-f) and T-O-acetyle-α-D-glucopyranosyle-Br in the presence of potassium carbonate as a weak base in acetone. The structure of the products was confirmed by FT-IR, H-NMR, and C-NMR assays. The antimicrobial properties of the newly synthesized compounds were studied against four bacterial strains, including Bacillus cereus, Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli, and two fungal strains, including Aspergillus niger and Candida albicans. Findings: The synthesized compounds exhibited better antifungal activity than antibacterial activity, espetially 7d. Among all the compounds, the compound 7d was found to have the highest activity against C. albicans with IZ=18±0.7 mm, MIC=250 mg/mL, and MFC= 250 mg/mL. Conclusion:The present study results indicated that compounds containing S-triazole had the potential to be used in a wide variety of new antifungal formulations.
