Several compounds with antagonistic actions on N-methyl-D-aspartate (NMDA) receptors were tested for an antiakinesic action in hypoactive MPTP-treated C57 BL/6 mice rendered tolerant to the motor activity enhancing effects of the 20 mg/kg, s.c., dose of L-Dopa; each compound was administered 60 min before the administration of the dopamine precursor. The classes of compounds studied included the noncompetitive NMDA antagonists, memantine, amantadine and MK-801, the competitive NMDA antagonist, CGP 40116, the anticonvulsive and putative anticonvulsive agents, lamotrigine and FCE 26743, with a partial glutamatergic antagonistic action. All six compounds elevated locomotor, rearing and total activity counts of L-Dopa-tolerant mice in co-administration with L-Dopa in dose-specific or dose-dependent manners but only memantine and MK-801 affected motor activity in the control mice, that also received chronic L-Dopa treatment. Thus, the restorative actions of those compounds in suprathreshold L-Dopa-tolerant MPTP-treated mice subjected to "wearing-off" of L-Dopa efficacy were assessed in a series of experiments. Within each class of potentially therapeutic agents a differential restorative efficacy of the motor activity-stimulating effects of hypoactive MPTP mice was obtained, confirming the putative antiparkinsonian applications of compounds with glutamate antagonistic actions.
