pubmed:abstractText |
New series of 4,5-disubstituted-2,4-dihydro-3H-1,2,4-triazole-3-thiones (8a-j) and 2,5-disubstituted-1,3,4-thiadiazoles (9a-h) were synthesized by dehydrative cyclization of hydrazinecarbothioamide derivatives (7a-k) by refluxing in 4N aqueous sodium hydroxide and by overnight stirring with polyphosphoric acid, respectively. The structures of the newly synthesized compounds were characterized by IR, (1)H NMR, (13)C NMR, elemental analysis and mass spectroscopic studies and the synthesized compounds were screened for their antioxidant and urease inhibition activities. N-(2,4-Dimethylphenyl)-5-(4-nitrophenyl)-1,3,4-thiadiazol-2-amine (9h) showed excellent antioxidant activity more than the standard drug whereas 4-(2,4-dimethylphenyl)-5-(3-nitrophenyl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (8d) and 4-(2,3-dimethylphenyl)-5-phenyl-2,4-dihydro-3H-1,2,4-triazole-3-thione (8e) exhibited potent urease inhibitory activities.
