Heterocyclic compounds containing the 1,2,4-triazole ring and the thiazolo[3,2-b][1,2,4]triazole fused ring system in their structure have been reported to exhibit antibacterial, antifungal, anticancer, anti-inflammatory and analgesic activities. Considering this fact, the aim of this study was the synthesis and characterization of novel thiazolo[3,2-b][1,2,4]triazole derivatives and their corresponding acyclic thioether intermediates, having different substituents which lead to anti-inflammatory activity. Thiazolo[3,2-b][1,2,4]triazole derivatives were obtained in a single step when the condensation between mercapto-triazoles and α-halogenocarbonyls was performed at reflux in acid catalysis, or via acyclic thioether intermediates, when the synthesis was performed at room temperature, in alkaline media. The synthesized compounds were purified and characterized by 1H NMR, 13C NMR, IR and MS. Their biological potential concerning anti-inflammatory and analgesic activities will be investigated in further studies.
