Purity: ≥98%
Dizocilpine (MK-801), is a novel, potent, selective and non-competitive NMDA ( N-Methyl-D-aspartate) receptor antagonist with Kd of 37.2 nM in rat brain membranes. (+)-MK-801 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 in test rats.
| ln Vitro |
Dizocilpine (MK-801) gradually reduces the current that is brought on by NMDA. Even after applying Dizocilpine for an extended period of time in the presence of NMDA, Mg2+ (10 mM) stops Dizocilpine from inhibiting the N-Me-D-Asp-induced current. Dizocilpine inhibits single-channel activity in outside-out patches that is triggered by NMDA[3]. When microglia are activated by LPS, BV-2 cells express more Cox-2 protein, and dizocilpine (MK-801; <500 μM) blocks this process. With an EC50 of 400 μM in BV-2 cells, dizocilpine (<500 μM) decreases microglial TNF-α production[4].

| ln Vivo |
Before each METH injection, mice receive a 1 mg/kg dose of dizocilpine (MK 801), which reduces the amount of DA depletion in the striatum by 55%. Additionally, METH's effects on microglial activation in the mouse striatal membrane are lessened by dizocilpine (MK 801) (1 mg/kg)[4]. ) before two reactivation sessions in the home cage exhibits no suppression on subsequent cocaine-primed reinstatement[5]. Dizocilpine ((+)-MK 801) (0.05, 0.2 mg/kg, ip) attenuates subsequent cocaine-primed reinstatement without disruption in rats.

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
