European journal of pharmacology, 338(3), 233-242 (1998-01-10)
N-Methyl-D-aspartate (NMDA)/glycine site antagonists were tested for their ability to prevent cocaine-induced convulsions and lethality in Swiss Webster mice. Pre-treatment of mice with the novel NMDA/glycine site antagonists ACEA-1021 (5-nitro-6,7-dichloro-1,4-dihydro-2,3-quinoxalinedione) or ACEA-1328 (5-nitro-6,7-dimethyl-1,4-dihydro-2,3-quinoxalinedione) attenuated cocaine-induced convulsions; these effects were pharmacologically

Multiple binding sites on the N-methyl-D-aspartate (NMDA) receptor complex were examined using rat brain synaptic membranes treated with Triton X-100. Binding of [3H](+)-5-methyl-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5,10-imi ne ([3H]MK-801), a noncompetitive NMDA antagonist, in the presence of 10 microM L-glutamate not only was inhibited
