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.[5]
It has been used to block the NMDA (N-methyl-D-aspartate) receptor-mediated rtPA (recombinant tissue plasminogen activator)-enhanced excitotoxic pathway.[6]
It is injected in varied doses to study behavioral performance altering effects of MK-801 in zebrafish (Danio rerio).[8]
It is used as a NMDA receptor antagonist to study 3-OH-GA-induced neuronal damage via NMDA receptors.[7]
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.[2] Experimental study shows that MK-801, influence circling behavior in a direction-specific manner, modify swimming activity and place preference in zebrafish.[3] Acute injection of MK-801, dose dependently, enhances extracellular acetylcholine (ACh) release in the rat parietal cortex.[4] For intracerebral hematomas, MK-801 might act as a potent supplement to reduce delayed edema after recombinant tissue plasminogen activator (rtPA) clot lysis.[6] MK-801 functions as an antidepressant in the social defeat stress model, but it doesn’t have long-lasting effect.[9]
