Central effects of CGP 37849 and CGP 39551, competitive NMDA receptor antagonists, were studied in male Albino-Swiss mice. CGP 37849--at high doses only--increased the locomotor activity, while CGP 39551 decreased it. CGP 37849 and CGP 39551 did not change the locomotor activity, in monoamine-depleted mice (treated with reserpine + alpha-methyltyrosine). However, when administered together with clonidine, both those compounds produced a distinct hyperactivity. That antiakinetic effect was antagonized by haloperidol, but not by prazosin or idazoxan. In monoamine-depleted mice both the CGP compounds inhibited the locomotor hyperactivity evoked by apomorphine or L-DOPA (given jointly with benserazide). CGP 37849 antagonized the catalepsy evoked by fluphenazine, haloperidol, spiperone and reserpine. After CGP 39551 administration, a decreased muscle tension was observed, which rendered evaluation of the influence on catalepsy impossible. The obtained results (the antiakinetic effect, antagonized by haloperidol, and the anticataleptic effect) indicate that the NMDA receptor antagonists studied may act via an indirect activation of the dopamine system.

UI	MeSH Term	Description	Entries
D007980	Levodopa	The naturally occurring form of DIHYDROXYPHENYLALANINE and the immediate precursor of DOPAMINE. Unlike dopamine itself, it can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to DOPAMINE. It is used for the treatment of PARKINSONIAN DISORDERS and is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system.

D008781	Methyltyrosines	A group of compounds that are methyl derivatives of the amino acid TYROSINE.
D009043	Motor Activity	Body movements of a human or an animal as a behavioral phenomenon.	Activities, Motor,Activity, Motor,Motor Activities
D012110	Reserpine	An alkaloid found in the roots of Rauwolfia serpentina and R. vomitoria. Reserpine inhibits the uptake of norepinephrine into storage vesicles resulting in depletion of catecholamines and serotonin from central and peripheral axon terminals. It has been used as an antihypertensive and an antipsychotic as well as a research tool, but its adverse effects limit its clinical use.

D002375	Catalepsy	A condition characterized by inactivity, decreased responsiveness to stimuli, and a tendency to maintain an immobile posture. The limbs tend to remain in whatever position they are placed (waxy flexibility). Catalepsy may be associated with PSYCHOTIC DISORDERS (e.g., SCHIZOPHRENIA, CATATONIC), nervous system drug toxicity, and other conditions.

D003000	Clonidine	An imidazoline sympatholytic agent that stimulates ALPHA-2 ADRENERGIC RECEPTORS and central IMIDAZOLINE RECEPTORS. It is commonly used in the management of HYPERTENSION.

D006220	Haloperidol	A phenyl-piperidinyl-butyrophenone that is used primarily to treat SCHIZOPHRENIA and other PSYCHOSES. It is also used in schizoaffective disorder, DELUSIONAL DISORDERS, ballism, and TOURETTE SYNDROME (a drug of choice) and occasionally as adjunctive therapy in INTELLECTUAL DISABILITY and the chorea of HUNTINGTON DISEASE. It is a potent antiemetic and is used in the treatment of intractable HICCUPS. (From AMA Drug Evaluations Annual, 1994, p279)	Haldol
