Abstract :

Objective of the study was to design and synthesize some new substitutes of 1,2,4-triazoles derived from isonicotinic acid hydrazides and screen for anti-tubercular activity. A series of new substituted 1,2,4-triazoles; isonicotinic acid hydrazide derivative (1ΓΆΒ?Β?28) were synthesized. Potassium dithiocarbazinate (1) was obtained from the reaction of isonicotinic acid hydrazide with carbon disulfide in basic medium (KOH) and converted into 4-amino-5-(pyridin-4-yl)-4H-1,2,4-triazole-3- thiol (2) by the treatment with hydrazine hydrate. The synthesis of the other compound was performed from the reaction of (2) with seven different benzaldehyde resulted in the formation of 4-[(substituted phenyl)-methylene]-amino-5-(pyridine-4- yl)-4H-1,2,4-triazol-3-thiol (3). The final compound synthesized from the reaction of 3 with four different acetanilide resulted in the formation of 4-[substituted phenyl)-methylene]-amino-3- (N-substitutedcarboxamidomethylthio)-5-(pyridine-4-yl)- 4H-1,2,4-triazoles (4). The structures of the synthesized compounds (1-28) were characterized by IR, 1H NMR, 13C NMR, mass spectroscopy and elemental method of analysis. IR data, 1H NMR spectra, 13C NMR spectra, mass spectra and elemental analysis indicates that 28 compounds were synthesized as proposed. In conclusion, their biological activities and study for toxicity are required.
