[Uses]

(-)-MK 801 Maleate was used in biological study to observe antipsychotics and other agents effects on prepulse inhibition of acoustic startle in rats. Binding properties of (-)-MK 801 Maleate, NMDA receptor channel blocker, were characterized in different brain regions
[Biological Activity]

(+)-mk 801 maleate is a potent antagonist of nmda with ki value of 30.5nm [1].mk 801 is a potent anticonvulsant exhibits both anxiolytic and sympathomimetic properties. it is found to be a noncompetitive antagonist of nmda. mk 801 can penetrate into the central nervous system. in the in vitro assay, mk 801 binds to rat cerebral cortical membrane with high affinity in a saturable manner. this binding is reversible even when the concentration of mk 801 is up to 100μm. it is also found that the binding shows a regional specificity. most of these binding sites are located in the hippocampus. in rat cortical-slice preparations, mk 801 causes a potent blockade of depolarizing responses to nmda with a high selectivity. this effect is persistent. the blockade can also cause a suppression of the epileptiform activity induced by tetrodotoxin or other neurotoxin [1].
[in vitro]

[3H]MK-801 labels high-affinity binding sites in rat cerebral cortical membranes in a saturable manner. It produces a potent blockade of depolarizing responses to NMDA in rat cerebral cortical slices. The only compounds that are able to compete for [3H]MK-801 binding sites are substances known to block the responses of excitatory amino acids mediated by the NMDA receptor subtype. MK-801 inhibits N-methyl-D -aspartate-induced [3H]norepinephrine (NE) release and [3H]TCP binding in the hippocampus with IC50 of 20 nM and 9 nM, respectively. MK- 801 causes a progressive, long-lasting blockade of current induced by NMDA. Mg2+ (10 mM) prevents MK-801 from blocking the N-Me-D-Asp-induced current, even when MK -801 is applied for a long time in the presence of NMDA. MK-801 is also effective at blocking NMDA-activated single-channel activity in outside-out patches. MK-801 (< 500 μM) prevents LPS-induced activation of microglia in a conce ntration-dependent manner with increased Cox-2 protein expression in BV-2 cells. MK-801 (< 500 μM) reduces microglial TNF-α output with EC50 of 400 μM in BV-2 cells.
[in vivo]

Treatment of mice with MK-801 (1 mg/kg) before each METH injection reduced the extent of DA depletion by 55% in striatal of mice. MK-801 (1 mg/kg) attenuates the effects of METH on microglial activation in striatal of mice. MK-801 (0.05 mg/kg or 0.2 mg/kg, ip) in rats just prior to reactivation of the cocaine-associated memory in the CPP context attenuates subsequent cocaine-primed reinstatement, while no disruption occurs in rats that do not receive reactivation in the CPP context. MK-801 (0.2 mg/kg, ip) prior to two reactivation sessions in the home cage does not suppress subsequent cocaine-primed reinstatement.
