Synthesis And Anticonvulsant Activity Of 3-Aryl-5h-2,3-Benzodiazepine Ampa Antagonists

A novel series of 3-aryl-5H-2,3-benzodiazepines. with N-3 aromatic substituents has been synthesized. Good in vivo anticonvulsant activity of the new compounds has been demonstrated employing the maximal electroshock seizure test in mice. Evaluation of a subset of the compounds in the cortical wedge assay confirmed the new structures to be AMPA antagonists. (C) 1999 Elsevier Science Ltd. All rights reserved.
