A series of hydrazones were synthesized by condensing substituted hydrazides with appropriate carbonyl compounds. The chemical structures of the synthesized compounds were confirmed by infrared, proton nuclear magnetic resonance, carbon-13 nuclear magnetic resonance, mass ((4-chloro-phenylamino)-acetic acid [1-(4-chlorophenyl)-phenyl-methylene]-hydrazide and (2,4-dichloro-phenylamino)-acetic acid (3-oxo- 1,3-dihydro-indole-2-ylidene)-hydrazide only) spectral data and carbon hydrogen nitrogen analysis. The title compounds were screened for their anticonvulsant activity against mice at doses of 30 mg/kg, 100 mg/kg and 300 mg/kg. The preliminary anticonvulsant screening data of this series resulted in the identification of two lead compounds (2,4-dichloro-phenylamino)-acetic acid (3-oxo-1,3-dihydro-indole- 2-ylidene)-hydrazide and (2,4-dichloro-phenylamino)-acetic acid [1-(4-chlorophenyl)-phenyl-methylene]- hydrazide with excellent preliminary anticonvulsant profile with no neurotoxicity in maximal electroshock seizure and subcutaneous metrazol mice model.
