(+)-MK 801 Maleate
(+)-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].

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 experiment [2]: | |
|
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. |
