A series of pharmacoplioric hybrids of ameltolide-gamma-aminobutyric acid (GABA)-amides was designed, synthesized, and evaluated for their anticonvulsant and neurotoxic properties. Initial anticonVUlsant screening was performed using intraperitoneal (ip) maximal electrosbock-induced seizure (MES), subcutaneous pentylenetetrazole (scPTZ), and subcutaneous picrotoxin (scPIC)induced seizure threshold tests. All the compounds had improved lipophilicity and the pharmacological activity profile confirmed their blood-brain barrier penetration. The titled compounds showed promising activity in scPIC screen indicating the involvement of GABA-mediation. Compound 4-(2-(2,6-dimetbylaminophenylamino)-2-oxoethylamino)-N-(2,6-dimethylphenyl) butanamide (7) emerged as the most potent derivative effective in all the three animal models of seizure with no neurotoxicity at the anticonvulsant dose.
