Abstact

A new set of quinazolinedione sulfonamide derivatives as competitive AMPA receptor antagonist with improved properties compared to 1 is disclosed. By modulating physico-chemical properties, compound 29 was identified with a low ED(50) of 5.5mg/kg in an animal model of anticonvulsant activity after oral dosage.
