Biological Activity for Memantine hydrochloride

Memantine hydrochloride is an antagonist at the NMDA receptor (IC50 = 0.5 -1.5 μM in vitro), binding to the ion channel site. Memantine increases BDNF protein and mRNA levels in the brain in vivo. In an animal model of Alzheimer's disease, memantine improves spatial learning and decreases deposition of Aβ plaques. Memantine has neuroprotective effects in dopaminergic neurons; stimulates release of neurotrophic factor from astroglia and reduces microglia inflammation in vitro.

Use-dependent block of NMDA receptors.
By Sergiy Sylantyev on 10/15/2020
Species: Human
Cell Line/Tissue: Stem cell - derived neurons

Memantine was used as a use-dependent blocker of NMDA receptors in nucleated patches pulled from stem-cell-derived dopamine neurons. Application of 0.5 µM memantine induced a significant decrease of NMDA receptors response. Washout for 4-5 minutes commonly returned the response amplitude to control values (see illustration).

Memantine hydrochloride in in vivo electrophysiology and in behavioral pharmacology.
By Zsolt Bali on 03/01/2019
Assay Type: In Vivo
Species: Rat

We have been using memantine hydrochloride from Tocris for behavioral pharmacology and in vivo electrophysiology in rats. In electrophysiology experiments, memantine was delivered with microiontophoresis into the close vicinity of the neurons during recording in the rat cerebral cortex. Memantine was successfully applied from glass micropipettes of multi-barrel electrodes with positive constant currents at acidic pH, and it exerted the expected effect on hippocampal neurons (see attached figure of a representative recording).In behavioral experiments, memantine enhanced cognitive function in scopolamine-induced transient amnesia in rats. However, we found that memantine was effective at substantially lower doses compared to most of the publications from other laboratories.

It is recommended to always perform an initial experiment for the assessment of the dose-response curve, and not to rely on available literature data regarding suggested suitable doses, since the effect of memantine may substantially differ in different assays or behavioral paradigms.
