The AMPA receptor antagonist GYKI 52466 reverses the anti-cataleptic effects of the competitive NMDA receptor antagonist CGP 37849.

The effects of the AMPA receptor antagonist GYKI 52466 (1-(4-aminophenyl)-4-methyl-7,8-methylenedioxy-5H-2,3-benzodiazepine HCl) on haloperidol-induced catalepsy were tested in drug-naive rats and in rats pretreated with the competitive NMDA receptor antagonist CGP 37849 (DL-(E)-2-amino-4-methyl-5-phosphono-3-pentenoic acid). CGP 37849 (4 mg/kg i.p.) given alone significantly reversed haloperid...

Activation of the NMDA/glutamate receptor complex antagonizes the NMDA antagonist-induced antidepressant-like effects in the forced swim test.

The antidepressant activity of NMDA receptor antagonists has been demonstrated, and their mechanism of action was based on the assumption of their selectivity for the NMDA receptor only. However, no direct evidence for the NMDA receptor role in this activity was demonstrated. Now, in order to prove the NMDA pathway of antidepressant-like action of the NMDA antagonists in the mouse forced swim t...

The NMDA antagonist dizocilpine (MK-801) reverses haloperidol-induced movement initiation deficits.

The present study shows that systemic dopamine receptor blockade impaired movement initiation of rats, trained in a simple reaction time task for rapid initiation of locomotion in response to a combined optic/acoustic cue. Reaction time, movement time and the accelerative force were recorded for each initiation of locomotion. Results indicate a dose-related increase of reaction time following s...

Orphenadrine-induced convulsive status epilepticus in rats responds to the NMDA antagonist dizocilpine.

BACKGROUND Identification of new molecular targets as well as the new models recapitulating different aspects of pathophysiology of status epilepticus (SE) in humans might prove essential for the breakthrough in the efforts against pharmacoresistance in epilepsy. Recently, we described a new model of generalized convulsive SE induced with orphenadrine (ORPH) in rats with unique characteristics ...

The ACTH(4-9) analog Org2766 modulates the behavioral changes induced by NMDA and the NMDA receptor antagonist AP5.

In studies on aged and brain-lesioned rats the chronic administration of the ACTH(4-9) analog Org2766 has been demonstrated to improve the behavioral performance. Those results suggest that maintenance of hippocampal functioning in senescence and facilitation of functional recovery after brain damage are not due to facilitated reinnervation of denervated structures as suggested in previous stud...
