Jr. Epperson et al., SYNTHESIS AND EXCITATORY AMINO-ACID PHARMACOLOGY OF SOME NOVEL QUINOXALINEDIONES, Bioorganic & medicinal chemistry letters, 3(12), 1993, pp. 2801-2804
The synthesis and amino acid pharmacology of twelve N-substituted quin
oxalinediones is reported. In particular, compounds 4a and 4b show sig

The functional antagonism of 4a has been demonstrated.
