(+)-MK-801 hydrogen maleate

(+)-MK-801 hydrogen maleate is a highly potent and selective non-competitive NMDA glutamate receptor antagonist that acts at the NMDA receptor-operated ion channel as an open channel blocker. Neurons are depolarized when MK-801 binds to the Glu (40 Glu) receptor (NMDA receptor- ion channel complex) at two sites. 40 Glu is the brain′s primary excitatory neurotransmitter. MK-801 attaches to the ion channel at the binding site PCP of the receptor. Receptor blockade occurs in a voltage-dependent manner. It also known as dizocilpine hydrogen maleate is an effective anticonvulsant with both anxiolytic and sympathomimetic properties.(+)-MK-801 hydrogen maleate stimulates locomotion in monoamine-depleted mice.

(+)-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.

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.

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.
