“…The acid hydrazide 6 was allowed to react with carbon disulphide in the presence of potassium hydroxide in methanol to give the corresponding potassium dithiocarbazinate 7. This salt underwent ring closure with an excess of hydrazine hydrate to give 4-amino-5-aryl-4H -1,2,4-triazole-3-thiol (8a-i) [1,21,22]. In the final step, treatment of the oxirane 4 with the appropriate thiol 8 in the presence of NaHCO 3 in absolute ethanol at room temperature gave final compounds 9a-i and 10a-i ( Table 1).…”

“…Since the antibacterial activity of 4-amino-3-mercapto-1,2,4-triazoles has been reported previously [21][22][23], thus the newly synthesized compounds were screened for antibacterial activity. The MIC values of compounds 9a-i and 10a-i were determined against Staphylococcus aureus (ATCC 6538), Staphylococcus epidermidis (ATCC 12228), Bacillus subtilis (ATCC 6633), E. coli (ATCC 8739), Pseudomonas aeruginosa (ATCC 9027) and Klebsiella pneumoniae (ATCC 10031) based on the conventional agar dilution method [24].…”

“…1,2,4‐Triazole is an important template that is connected with several biological activities as antibacterial, anticholinergic, analgesic, and antiasthmatic . Likewise, triazoles are utilized in several antifungal medicines as well as fungicides . There is considerable interest in the chemistry of heterocyclic thiones, because they are ambidextrous or multifunctional donors with sulfur or nitrogen atom.…”

“…Їхні антибактеріальні властивості досліджено стосов но чотирьох бактеріальних штамів, а саме: S. aureus (atcc25923), P. aeruginosa (atcc27853), E. coli (atcc8739), B. subtilis (atcc6633), а також штамів грибів -C. albicans (mtcc227), A. niger (mtcc3323) та F. Oxysporum (mtcc2087). Попе редні результати свідчать, що деякі з них виявляють високу активність і заслугову ють подальшого розгляду [14].…”
