Background: 3, 2, 1 triazoles are an important class of five-membered heterocyclic compounds whose unique biological properties have made them an important class of chemical compounds. The biological activity of these compounds is known as anti-fungal, anti-bacterial, anti-tumor, anti-inflammatory, anti-depressant, anti-tuberculosis, anti-HIV, etc. Materials and methods: In this research, first we synthesized new courcomin catalyst. We investigated synthesis of some 1, 2, 3 triazol derivatives and evaluated their anti-bacterial and anti-fungal effects. After synthesis and purification of some 1, 2, 3-triazol compound, the inhibitory effect of compounds against fungal (Candida albicans, Aspergillus niger) and against bacterial (Staphylococcus arueus and Escherichia coli) was evaluated. Results: It was found that compound (3): 1-(4-bromobenzyl)-1H-1, 2, 3-triazol-4-ol exhibited the best antifungal activities. Also this compound showed good activity against Staphylococcus areus as a Gram-positive bacteria. Conclusion: According to the results, it seems that the use of recombinant substance 3 as a new compound with acceptable antimicrobial properties can be considered
