The synthesis and anticonvulsant activity of novel 7,8-methylenedioxy-4H-2,3-benzodiazepin-4-ones 3a-e, structurally-related to GYKI 52466 1, a well-known noncompetitive AMPA-receptor antagonist, are reported. The new compounds possess marked anticonvulsant properties and, in analogy to 1, antagonize seizures induced by AMPA. In addition, when compared to the model compound 1, compounds 3 show a longer-lasting anticonvulsant activity and a lower toxicity. (C) 1998 Elsevier Science Ltd. All rights reserved.
