In the present investigation, we described herein the molecular properties prediction by Molinspiration (2008) and synthesized a series of 17 2-(substituted benzylidene/ethylidene)-N-(substituted phenyl) hydrazinecarboxamide analogues. All the title compounds (4a-q) followed the Lipinski "Rule of Five." The synthesized compounds were characterised by elemental analyses and spectral data followed by anticonvulsant activity according to the Antiepileptic Drug Development Programme Protocol. 2-(4-Hydroxybenzylidene)-N-(2-chlorophenyl)hydrazinecarboxamide (4j) was found to be the most active compound of the series showing protection at 4.0 h at a dose of 100 mg/kg against maximal electroshock seizure test and 50 % (2/4, 0.25, 1-2 h) and 100 % (4/4, 0.5 h) protection in 6 Hz psychomotor seizure test without showing any neurotoxicity. N-(2-chlorophenyl)hydrazine carboxamide (3b) showed 100 % (4/4, 0.25-2 h) and 66.6 % (2/3, 4 h) protection in 6 Hz psychomotor seizure test.
