摘要
Various 2.4-dimethoxyphenylsemicarbazones were synthesized starting from 2,4-dimethoxyaniline via a phenylcarbamate intermediate. The structures were confirmed by spectral and elemental analyses. The anticonvulsant activity of the synthesized compounds was established after intraperitoneal administration in three seizure models in mice which include maximal electroshock seizure, Subcutaneous pentylenetetrazole, and subcutaneous strychnine-induced seizure screens. Nine Compounds exhibited protection in all the three seizure models, and N-1-(2,4-dimethoxyphenyl)-N-4-(propan-2-one)semicarbazone (17) emerged as the most active compound with no neurotoxicity. These compounds were found to elevate gamma-aminobutyric acid (GABA) levels in the midbrain and medulla oblongata regions equipotent to clobazam. (c) 2006 Elsevier Ltd. All rights reserved.
