A series of five 6,7-disubstituted 1,4-dihydro-2,3-quinoxalinediones was prepared, two of which are known microbial flavin metabolites and three of which are potential flavin metabolites. Four of the five compounds inhibited specific binding of [3H]-amino-3-hydroxy-5-methyl-4-isoxazolepropanoic acid ([3H]AMPA), [3H]kainic acid, and [3H]6-cyano-1,4-dihydro-7-nitro-2,3- quinoxalinedione ([3H]CNQX) in rat brain homogenate fractions, with IC50 values in the low micromolar range (the fifth compound competed only with [3H]CNQX). Two of the compounds were moderately potent AMPA antagonists in an in vitro functional test.
