    Neurons are pre-treated with 10 μM Dizocilpine (MK801), followed by TNF-α treatment (40 ng/mL, 2 h). MK801 could attenuate TNF-α- induced intracellular calcium accumulation, phosphorylation of CAMK II and calpain-2, calpain activation and cathepsin B release as well as TrkB truncation.

    Dizocilpine maleate purchased from MedChemExpress. Usage Cited in: Neuroreport. 2017 May 24;28(8):444-450.  [Abstract]

    Western blot analysis confirms that MK-801 inhibits the decrease in GDF10 in SNL rats. The relative expression level of GDF10 in the SNL-vehicle group is significantly decreased, but remains unchanged in the SNL-MK-801 group versus sham.

    Description

    Dizocilpine maleate (MK-801 maleate) is a potent, selective and non-competitive NMDA receptor antagonist with Kd of 37.2 nM in rat brain membranes.

    IC50 & Target

    NMDA Receptor

     

    In Vitro

    [3H]Dizocilpine maleate binds with NMDA receptor with a Kd of 37.2±2.7 nM in rat cerebral cortical membranes[1].
    Dizocilpine maleate causes a progressive, long-lasting blockade of current induced by N-Me-D-Asp[3].
    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[3].
    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[4].

    Animal Administration
    [5]

    Animals are given saline or Dizocilpine ((+)-MK 801) followed by cocaine 30 min later in the home cage instead of in the CPP apparatus for the two days of “reactivation.” This is done to determine whether reactivation of the memory for the cocaine-associated context by cocaine in the CPP context is necessary for the ability of Dizocilpine ((+)-MK 801) to disrupt reconsolidation. Animals undergo preconditioning, conditioning, testing, and extinction but animals are injected with saline or Dizocilpine ((+)-MK 801) (0.20 mg/kg, i.p.) 30 min prior to a cocaine injection (10 mg/kg, i.p.) in the home cage. Animals remain in the home cages, and the next day, the procedure from the first day of reactivation is repeated. The following day, animals are tested for cocaine-primed reinstatement in their CPP box without any prior microinjection of saline or Dizocilpine ((+)-MK 801).

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
