A series of four N-benzylamides of γ-hydroxybutyric acid (GHB), that contain N-(4-phenylpiperazine)-, N-(4-benzylpiperazine)rings, N-benzylamino-, or N-(2-phenylethylamine)-groups in the α-position of GHB were selected as model compounds, for determining the structural elements responsible for their potential anticonvulsant action. Based on the results of pharmacological, physicochemical, and molecular modelling investigations, the pharmacophore model for anticonvulsant N-substituted amides of GHB was defined. In this model, the presence of the N-benzylamide fragment is essential for activity. In addition, all of the amides contained another hydrophobic unit (aryl ring) as a distal binding site and H-bond donor. In consideration of these model parameters, a number of N-substituted amides of GHB, containing a hydrophobic moiety such as: N-benzylamino or N-(4-chlorobenzylamino) group in the α-position of GHB, and a lipophilic substituent in the amide portion, were prepared. It has been shown that the anticonvulsant activities of the newly synthesized compounds might partially be explained on the basis of their lipophilicity (calculated log P values) and the presence of a hydroxyl group in the molecule.
