产品介绍
(+)-MK 801 Maleate (MK-801 maleate) 是一种有效的、选择性的、非竞争性的 NMDA 受体拮抗剂,在大鼠脑膜中的 Kd 值为 37.2 nM。

Cell lines

Primary mixed neuronal/glial cultures from fetal rat brains.

Preparation method

The solubility of this compound in DMSO is >16.9mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

10 μM for 30 minutes

Applications

NMDA induced apoptosis in mixed neuronal/glial cell cultures. In the presence of a mild excitotoxic insult, this investigation showed an attenuation of apoptotic cell death by MK 801.

Animal models

C57BL/6; BALB/c mice

Dosage form

s.c. or i.p., 0.1 mg kg(-1)

Application

MK 801 in the chronically C57BL/6 chronic stress group that prevented weight gain deficit. For the C57BL/6 strain chronic MK 801 produced an alteration of the fur state. In the CA1 layer of chronically stressed C57BL/6 mice, MK 801 induced an increase of VGLUT1 immunoreactivity. For the BALB/c group, MK 801 enhanced BDNF mRNA in the chronic stress group in the DG. In the chronically stressed BALB/c mice, MK 801 prevented stressed induced VGLUT3 immunoreactivity up-regulation in the CA3 layer.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

产品描述

(+)-MK 801 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].
