Product Information

(+)MK-801 maleate is an uncompetitive antagonist of the N-Methyl-D-aspartate (NMDA) receptor. Dizocilpine blocks NMDA receptors in a use- and voltage-dependent manner, since the channel must open for the drug to bind inside it. The drug acts as a potent anti-convulsant and likely has dissociative anesthetic properties, but it is not used clinically for this purpose due to the discovery of brain lesions, called Olney's lesions (see below), in test rats. Dizocilpine is the most frequently used non-competitive NMDA receptor antagonist in animal models to mimic psychosis for experimental purposes.

In Vitro

[3H]Dizocilpine maleate binds with NMDA receptor with a Kd of 37.2±2.7 nM in rat cerebral cortical membranes.

Dizocilpine maleate causes a progressive, long-lasting blockade of current induced by N-Me-D-Asp.

Dizocilpine maleate progressively suppresses of current induced by NMDA. Mg2+ (10 mM) prevents Dizocilpine from blocking the N-Me-D-Asp-induced current, even when Dizocilpine (MK-801) is applied for a long time in the presence of NMDA. Dizocilpine blocks NMDA-activated single-channel activity in outside-out patches.

Dizocilpine maleate (< 500 μM) inhibits activation of microglia induced by LPS with increased Cox-2 protein expression in BV-2 cells. Dizocilpine (MK-801; <500 μM) reduces microglial TNF-α output with an EC50 of 400 μM in BV-2 cells.

 

In Vivo:

Dizocilpine maleate (MK 801 maleate) (1 mg/kg) treatment before each METH injection reduces the extent of DA depletion by 55% in striatal of mice. Dizocilpine (MK 801) (1 mg/kg) also attenuates the effects of METH on microglial activation in striatal of mice.

Dizocilpine maleate (0.05, 0.2 mg/kg, i.p.) attenuates subsequent cocaine-primed reinstatement without disruption in rats. Dizocilpine maleate (0.2 mg/kg, i.p.) prior to two reactivation sessions in the home cage shows no suppression on subsequent cocaine-primed reinstatement.

Dizocilpine maleate (0.03, 0.1, 0.3 and 1 mg/kg, i.p.) significantly increases the ambulation of mice at 0.3 and 1 mg/kg, but not at 0.03 and 0.1 mg/kg.
