Design, synthesis and biological evaluation of novel thiosemicarbazide analogues as potent anticonvulsant agents
摘要:
Novel thiosemicarbazide derivatives were synthesised and evaluated for their anticonvulsant activity and neurotoxicity. Anticonvulsant activity was done for grand mal and petit mal types of epilepsies by maximal electroshock (MES) and pentylenetetrazol (PTZ) induced convulsions methods respectively. Rotarod test was done to determine neurotoxicity. Amongst synthesised compounds, N-(4-bromophenyl) 2-[(2-phenylhydrazinyl) carbonothioyl] hydrazinecarbothioamide (5e) is a broad-spectrum anticonvulsant agent since it was active in both (MES) and (PTZ) induced seizure models with no neurotoxicity and N, N-(bis(chlorophenyl) hydrazine-1,2-dicarbothoamide (5g) acts as a selective agent for grand mal epilepsy.
