Synthesis and biological activity of some novel derivatives of 4-amino-3-(D-galactopentitol-1-yl)-5-mercapto-1,2,4-triazole.
To discover new 1,2,4-triazole derivatives which may possess significant biological activities, we synthesized a series of novel 6-aryl-3-(D-galactopentitol-1-yl)-7H-1,2,4-triazolo[3,4-b][1,3,4]thiadiazines and 4-(arylmethylidene)amino-5-(D-galactopentitol-1-yl)-3-mercapto-4H-1,2,4-triazoles from 4-amino-3-(D-galactopentitol-1-yl)-5-mercapto-1,2,4-triazole. All the title compounds were characte...
متن کامل4-Amino-3-(4-pyridyl)-1,2,4-triazole-5(4H)-thione
In the title mol-ecule, C(7)H(7)N(5)S, the pyridyl and triazole rings form a dihedral angle of 20.07 (6)°. Inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into chains extended in the direction [10]. Further stability is provided by π⋯π stacking inter-actions, indicated by short distances between the centroids of triazole rings [3.480 (5) Å] and pyridyl rings [3.574 (5) Å] of neighbouri...
متن کاملSynthesis of novel derivatives of 4-amino-3-(2-furyl)-5-mercapto-1,2,4-triazole as potential HIV-1 NNRTIs.
A series of 5-alkylthio (2a-d), 4-arylideneamino (3a-d) and 4-arylideneamino-5-alkylthio derivatives (4a-f) of 4-amino-3-(2-furyl)-5-mercapto-1,2,4-triazole (1) were synthesized by alkylation of the parent compound with alkyl halides and condensation with aldehydes, respectively. Sulfanyl dimers 5a-d and 4-iminomethyl dimer 6 were correspondingly prepared by reaction with alkane dibromides and ...
متن کاملUrate oxidase electrode based on dissolved oxygen probe for urine uric acid determination.
A biosensor for the specific determination of uric acid in urine was developed using urate oxidase (EC 1.7.3.3) in combination with a dissolved oxygen probe. Urate oxidase was immobilized with gelatin by means of glutaraldehyde and fixed on a pretreated teflon membrane to serve as enzyme electrode. The electrode response was maximum when 50 mM glycine buffer was used at pH 9.2 and 35 degrees C....
متن کامل4-Amino-3-phenyl-1H-1,2,4-triazole-5(4H)-thione
In the title compound, C(8)H(8)N(4)S, the planar triazole ring forms a dihedral angle of 13.7 (2)° with the phenyl ring. The crystal structure is stabilized by inter-molecular N-H⋯S hydrogen-bond inter-actions, linking the mol-ecules into chains along the a axis.
