A series of cyclic analogues of bioactive thiosemicarbazide derivatives have been synthesized as potential antimycobacterial agents. The 4-amino-1,2,4-triazole-5-thione analogues (Ia-f) were prepared by heating a mixture of thiocarbohydrzide and appropriate carboxylic acids. Reaction of thiocarbohydrazide with γ-ketoesters in the presence of sodium methoxide furnished triazolopyridazine derivat...
Metabolites of β2-agonists 2-(4-amino-3,5-dichlorophenyl)-2-(alkylamino)ethanols, derivatives hippuric and mandelic acids, were synthesized. The excretion profiles the target compounds metabolites with urine studied in experiments on laboratory animals. 2-(4-Amino-3,5-dichlorophenyl)-2-(isopropylamino) ethanol (9.7% administered dose) 2-(4-amino-3,5-dichlorophenyl)-2-(tert-amylamino)ethanol (0....
substituted schiff bases (hydrazones) 5a-j have been prepared from the starting material 2-chloro pyridine-3-carboxylic acid 1 by a sequence of reactions like reaction with 2-amino-6-nitro benzothiazole (ullamann condensation), thionyl chloride, hydrazine hydrate and different aromatic aldehydes. on cyclocondensation of 5a-j with thioglycolic acid in dry 1,4-dioxane furnished desired compounds ...
