MK-801

SKU: orb1224034

Description

MK-801 (Dizocilpine) is a potent N-methyl-D-aspartate (NMDA) receptor antagonist with Ki of 30.5 nM.(In Vitro):Dizocilpine (MK-801) progressively suppresses of current induced by NMDA. Mg2+ (10 mM) prevents Dizocilpine from blocking the N-Me-D-Asp-induced current, even when Dizocilpine is applied for a long time in the presence of NMDA. Dizocilpine blocks NMDA-activated single-channel activity in outside-out patches.Dizocilpine (MK-801; <500 μM) inhibits activation of microglia induced by LPS with increased Cox-2 protein expression in BV-2 cells. Dizocilpine (<500 μM) reduces microglial TNF-α output with an EC50 of 400 μM in BV-2 cells.(In Vivo):Dizocilpine (MK 801) (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 ((+)-MK 801) (0.05, 0.2 mg/kg, i.p.) attenuates subsequent cocaine-primed reinstatement without disruption in rats. Dizocilpine (MK 801) (0.2 mg/kg, i.p.) prior to two reactivation sessions in the home cage shows no suppression on subsequent cocaine-primed reinstatement.
