Thirty six new N-(4-substituted phenyl)-2-[4-(substituted) benzylidene]-hydrazinecarbothioamides were synthesized and evaluated for anticonvulsant activity and neurotoxicity. The anticonvulsant activity was established in three seizure models i.e. MES, scMET and 6 Hz model. The most active compound was 2-[4-(4-chlorophenoxy)benzylidene]-N-(4-fluorophenyl)hydrazinecarbothioamide PC 31 which showed 100% protection at 0.5 h in the 6 Hz test. Compound 2-[4-(4-bromophenoxy) benzylidene]-N-(4-bromophenyl) hydrazinecarbothioamide PC 23 was found to be active in both the MES and 6 Hz test. A computational study was carried out from calculation of a pharmacophore pattern and the prediction of pharmacokinetic properties. Titled compounds have also exhibited good binding properties with epilepsy molecular targets such as glutamate, GABA (A) delta and GABA (A) alpha-1 receptors, in the Lamarckian genetic algorithm based on flexible docking studies.
