[Ability of novel non-competitive glutamate receptor blocking agents to weaken motor disorders in animals].

Action of mono- and dication derivatives of phenylcyclohexyl was compared with effects of known NMDA-antagonists memantine and dizocilpine. Seizures induced with the NMDA were effectively prevented both by mono- and dications, whereas against the kainate seizures dication alone was effective. Anticataleptic activity was much stronger in monocations, and the side effect of the substances under study on motor co-ordination was obviously weaker than in dizocilpine. Thereupon, the phenylcyclohexyl derivatives might be regarded as potential means for treatment of parkinsonism and other motor disorders.
