A series of novel N-1-{5-[(naphthalene-2-yloxy)methyl]-1,3,4-oxadiazol-2-yl}-N-4-(4-substitutedbenzaldehyde)-semicarbazone, N-1-{5-[(naphthalene-2-yloxy)methyl]-1,3,4-oxadiazol-2-yl}-N-4-[1-(4-substitutedphenyl) ethanone]-semicarbazone and N-1-{5-[(naphthalene-2-yloxy)methyl]-1,3,4-oxadiazol-2-yl}-N-4-[1-(4-substitutedphenyl) (phenyl) methanone]-semicarbazone were designed and synthesized on the basis of semicarbazone based pharmacophoric model to meet the structural requirements necessary for anticonvulsant activity. The anticonvulsant activities of the compounds were investigated using maximal electroshock seizure (MES), subcutaneous pentylenetrtrazole (scPTZ) and subcutaneous strychnine (scSTY) models. Some of the selected active compounds were subjected to GABA assay to confirm their mode of action. The efforts were also made to establish structure activity relationships among synthesized compounds. The results of the present studying validated that the pharmacophoric model with four binding sites is essential for anticonvulsant activity. (C) 2010 Elsevier Ltd. All rights reserved.
