Description of "1,3,4-OXADIAZOLE"
Oxadiazole is bioactive class of compounds and its derivatives are used widely in drugs and for the treatment of many diseases like neuro-disorders, muscle disorders etc. In the undertaken research work, a series of S-substituted derivatives of 5-(4-nitrophenyl)-1,3,4-oxadiazole-2-thiol (6a-l) were synthesized in various steps. Organic acid 4-nitrobenzoic acid (1) was successfully converted into ester and consequently into its hydrazide in the presence of hydrazine hydrated and methanol as a solvent. Further, 4-nitrobenzoic acid hydrazide (3) yielded 5-(4-nitrophenyl)-1,3,4-oxadiazole-2-thiol, on treatment with carbon disulfide in the presence of base (KOH) and ethanol. Finally the target compounds (6a-l) were obtained by stirring 5-(4-nitrophenyl)-1,3,4-oxadiazole-2-thiol with different electrophiles (5a-l) in the presence of sodium hydride (NaH) and dimethyl formamide (DMF). All these derivatives along with their parent compounds were characterized by IR, EI-MS and 1H-NMR. All the synthesized compounds were assayed for their antioxidant activities and other biological activities. The compounds were screened against Acetylcholinesterase (AChE), Butyrylcholinesterase (BChE) and Lipoxygenase (LOX) enzymes and showed prominent activity against Acetylcholinesterase and Butyrylcholinesterase enzymes.
