1,4-Disubstituted-semicarbazide and thiosemicarbazide derivatives were synthetized from 5-substituted-4-oxo-1,4-dihydro-3-pyridinecarbohydrazides and cyclized to 3-mercapto-4H-1,2,4-triazoles. The obtained compounds could be S-methylated with methyl iodide in methanol. The new compounds were tested for antibacterial and antifungal activities.
