6.2.8 Glutamate Receptor Antagonists. The most abundant excitatory neurotransmitter in the CNS is glutamate. This essential molecule has three different receptors in the mammalian nervous system: NMDA, AMPA, and kainite receptors. All of these receptors allow the influx of Ca 2+ ions into the neuron.
Furthermore, because glutamate receptor antagonists, particularly those acting on NMDA receptors, protect effectively in the induction of kindling, it was suggested that they may have utility in epilepsy prophylaxis, for example, after head trauma.

The PSJ Award for Drug Research and … 2004-08-10 Although glutamate receptors, which are responsible for neuronal excitation, have long been recognized as important drug discovery targets, they have not led to the creation of any drugs. By optimizing the structure of the lead compound obtained from uniquely constructed high-throughput screening (HTS), oral absorption, brain permeability, pharmacokinetics, subtype selectivity, etc. were improved. 1999-03-01 2016-09-23 2021-03-26 2017-04-01 Eisai: Discovery Research on AMPA-type Glutamate Receptor Antagonist Perampanel Honored With PSJ Award for Drug Research and Development 2021 Article Stock Quotes (1) FREE Breaking News Alerts Glutamate Receptor Antagonist Modeling the Psychopathological Dimensions of Schizophrenia.

To clarify this, studies were done on Swiss mice with adenosine receptor agonists and antagonists.
The metabotropic glutamate receptors, or mGluRs, are a type of glutamate receptor that are active through an indirect metabotropic process. They are members of the group C family of G-protein-coupled receptors, or GPCRs. Like all glutamate receptors, mGluRs bind with glutamate, an amino acid that functions as an excitatory neurotransmitter.

Michaelis EK, Freed WJ, Galton N, Foye J, Michaelis ML, Phillips I, Kleinman JE: Glutamate receptor changes in brain synaptic membranes from human This study investigated synovial fluid glutamate concentrations and glutamate receptor (GluR) expression in injured human joints and compared the efficacy of GluR antagonists with current treatments in a mouse model of injury-induced osteoarthritis (ACL rupture). Kainate receptors, or kainic acid receptors (KARs), are ionotropic receptors that respond to the neurotransmitter glutamate.They were first identified as a distinct receptor type through their selective activation by the agonist kainate, a drug first isolated from algae.
With epileptic seizures being mediated by the neurotransmitter glutamate, the agent is a highly selective, noncompetitive AMPA receptor antagonist that reduces neuronal hyperexcitation associated with seizures by targeting glutamate activity at AMPA receptors on postsynaptic membranes. 2019-02-04

Magnesium is one of many antagonists at the glutamate receptor, and magnesium deficiencies have demonstrated relationships with many glutamate receptor-related conditions.
The metabotropic glutamate receptors, or mGluRs, are a type of glutamate receptor that are active through an indirect metabotropic process. They are members of the group C family of G-protein-coupled receptors, or GPCRs. Like all glutamate receptors, mGluRs bind with glutamate, an amino acid that functions as an excitatory neurotransmitter. Glutamate Receptors. L-Glutamate is the major excitatory neurotransmitter in the mammalian CNS. It acts via two classes of receptors, ligand gated ion channels ( ionotropic receptors) and G-protein coupled ( metabotropic) receptors. Activation of these receptors is responsible for basal excitatory synaptic transmission and many forms of The predominant role of glutamate in cocaine-induced reinstatement was demonstrated by the finding that the microinjection of a dopamine receptor antagonist into the NAS only blocked reinstatement
