(+)-MK-801 HYDROGEN MALEATE (C005B-454904)

General description

MK-801 [(+)-5-methyl-10,11-dihydroxy-5H-dibenzo(a,d)cyclohepten-5,10-imine] also known as dizocilpine hydrogen maleate is an effective anticonvulsant with both anxiolytic and sympathomimetic properties.

Application

(+)-MK-801 hydrogen maleate has been used in following experimental studies:
It is injected to mice to study the effect of systemic administration of CIQ [(3-chlorophenyl) (6, 7-dimethoxy-1-((4-methoxyphenoxy) methyl)-3, 4-dihydroisoquinolin-2(1H)-yl)methanone] on schizophrenia-like behaviours stimulated by MK-801.
It has been used to block the NMDA (N-methyl-D-aspartate) receptor-mediated rtPA (recombinant tissue plasminogen activator)-enhanced excitotoxic pathway.
It is injected in varied doses to study behavioral performance altering effects of MK-801 in zebrafish (Danio rerio).
It is used as a NMDA receptor antagonist to study 3-OH-GA-induced neuronal damage via NMDA receptors.

Biochem/physiol Actions

Highly potent and selective non-competitive NMDA glutamate receptor antagonist that acts at the NMDA receptor-operated ion channel as an open channel blocker. Inhibits behavioral sensitization to psychostimulants and ethanol.

MK-801 [(+)-5-methyl-10, 11-dihydroxy-5H-dibenzo (a, d) cyclohepten-5, 10-imine] functions as a selective non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist and stimulates locomotion in monoamine-depleted mice. Experimental study shows that MK-801, influence circling behavior in a direction-specific manner, modify swimming activity and place preference in zebrafish. Acute injection of MK-801, dose dependently, enhances extracellular acetylcholine (ACh) release in the rat parietal cortex. For intracerebral hematomas, MK-801 might act as a potent supplement to reduce delayed edema after recombinant tissue plasminogen activator (rtPA) clot lysis. MK-801 functions as an antidepressant in the social defeat stress model, but it doesn′t have long-lasting effect.
