An in vivo radioligand binding assay for the N-methyl-D-aspartate (NMDA) receptor channel complex in the mouse brain has been developed using the non-competitive NMDA receptor antagonist [3H]MK-801. In vivo binding of [3H]MK-801 was displaced by MK-801 (ED50 = 0.17 mg/kg i.p.), (-)-MK-801 (1.0 mg/kg), thienylcyclohexylpiperidine (1.8 mg/kg), etoxadrol (5.1 mg/kg) and (+)-SKF 10,047 (34.5 mg/kg). The potency of these drugs in this in vivo binding assay was highly correlated (r = 0.97) with their functional effects as antagonists of N-methyl-DL-aspartate-induced tonic convulsions.
