A range of derivatives of sulfonyl-substituted nitrogen-containing heterocyclic systems has been extended by synthesis of 2N (R)-5R1-1, 3, 4-thiadiazol-2-yl-arylsulfonamides and N-(diethylsulfamoyl)-N-(5-ethyl-1, 3, 4thiadiazol-2-yl)benzamides. It was established that acylation of 5-ethylsulfanyl-1, 3, 4-thiadiazole-2-amine by heteryl-substituted acid chlorides allowed for obtaining not reported in the literature heterocyclic compounds, which structure contained two cycles of 1, 3, 4-thiadiazole. The structure and purity of the obtained compounds was confirmed by 1H NMR-spectroscopy, elemental analysis, and thin-layer chromatography. Pharmacological studies on antimicrobial and antifungal activity have shown that all the compounds tested have sensitivity to both Gram-positive, and Gram-negative bacteria. In addition, the obtained substances have exhibited antifungal activity against Candida albicans. The studies have identified compound 4-butoxy-N-{5-[({[5-(ethylsulfanyl)1, 3, 4-thiadiazol-2-yl] carbomoyl} methyl) sulfanyl]-1, 3, 4-thiadiazol-2-yl} benzamide with high antimicrobial activity further studies of which are promising.



Synthesis, 2.5-disubstituted 1, 3, 4-tiadiazoles, antibacterial and antifungal activity.
