Design of semicarbazones and their bio-isosteric analogues as potential anticonvulsants.
A series of semicarbazones and hydrazones were prepared and evaluated for anticonvulsant activity. Some compounds provided significant protection against maximal electroshock (MES) and subcutaneous strychnine induced seizures (ScSty). Compound 2a emerged as the most active compound at a dose of 30 mg/kg in ScSty test. The compounds 1a, 1g and 2a-e showed significant potentiation of sedative and hypnotic activity of pentobarbitone sodium. Thus compound 2a could serve as a prototype for future developments.
