The invention discloses novel fused-azacylic quinoxalinediones. These compounds may be employed as excitatory amino acid antagonists and as analogs for use in immunological assays. The invention is also directed to both a radioimmunoassay and enzyme immunoassay for detecting and quantitating 1,4,7,8,9,10,-hexahydro-9-methyl-6-nitropyrido[3,4-f]-quinoxaline-2,3-dione PNQX and analogs thereof. |
