Metabotropic Glutamate Receptor 2
Metabotropic glutamate receptor 2 (mGluR2) is a protein that, in humans, is encoded by the ''GRM2'' gene. mGluR2 is a G protein-coupled receptor (GPCR) that couples with the Gi alpha subunit. The receptor functions as an autoreceptor for glutamate, that upon activation, inhibits the emptying of vesicular contents at the presynaptic terminal of glutamatergic neurons. Structure In humans, mGluR2 is encoded by the ''GRM2'' gene on chromosome 3. At least three protein-coding isoforms are predicted based on genomic information, as well as numerous non-coding isoforms. The mGluR2 protein is a seven-pass transmembrane protein. Function In humans, mGluR2 is only expressed in the brain, and not in any other tissue. In the brain, mGluR2 is expressed in neurons as well as astrocytes. Subcellularly, mGluR2 is predominantly positioned at the presynaptic terminal, although it is also expressed at the postsynaptic terminal. The metabotropic glutamate receptors are a family of G protein-co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residue (biochemistry), residues. Proteins perform a vast array of functions within organisms, including Enzyme catalysis, catalysing metabolic reactions, DNA replication, Cell signaling, responding to stimuli, providing Cytoskeleton, structure to cells and Fibrous protein, organisms, and Intracellular transport, transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the Nucleic acid sequence, nucleotide sequence of their genes, and which usually results in protein folding into a specific Protein structure, 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called pep ...

GPCR Oligomer
A GPCR oligomer is a protein complex that consists of a small number ( ''oligoi'' "a few", ''méros'' "part, piece, component") of G protein-coupled receptors (GPCRs). It is held together by covalent bonds or by intermolecular forces. The subunits within this complex are called protomers, while unconnected receptors are called monomers. Receptor homomers consist of identical protomers, while heteromers consist of different protomers. Receptor homodimers – which consist of two identical GPCRs – are the simplest homomeric GPCR oligomers. Receptor heterodimers – which consist of two different GPCRs – are the simplest heteromeric GPCR oligomers. The existence of receptor oligomers is a general phenomenon, whose discovery has superseded the prevailing paradigmatic concept of the function of receptors as plain monomers, and has far-reaching implications for the understanding of neurobiological diseases as well as for the development of drugs.

Psychedelic Drug
Psychedelics are a subclass of hallucinogenic drugs whose primary effect is to trigger non-ordinary mental states (known as psychedelic experiences or "trips") and a perceived "expansion of consciousness". Also referred to as classic hallucinogens or serotonergic hallucinogens, the term ''psychedelic'' is sometimes used more broadly to include various other types of hallucinogens as well, such as those which are atypical or adjacent to psychedelia like salvia and MDMA, respectively. Classic psychedelics generally cause specific psychological, visual, and auditory changes, and oftentimes a substantially altered state of consciousness. They have had the largest influence on science and culture, and include mescaline, LSD, psilocybin, and DMT. There are a large number of both naturally occurring and synthetic serotonergic psychedelics. Most psychedelic drugs fall into one of the three families of chemical compounds: tryptamines, phenethylamines, or lysergamides. T ...

RO4491533
RO-4491533 is a drug developed by Hoffmann-La Roche which acts as a potency (pharmacology), potent and binding selectivity, selective negative allosteric modulator for Metabotropic glutamate receptor#Group II and Group III, group II of the metabotropic glutamate receptors (Metabotropic glutamate receptor, mGluR2/3), being equipotent at mGluR2 and mGluR3 but without activity at other mGluR subtypes. In animal studies, RO-4491533 produced antidepressant effects and reversed the effects of the mGluR2/3 agonist LY-379,268 with similar efficacy but slightly lower potency than the mGluR2/3 antagonist LY-341,495. A number of related compounds are known, with similar effects ''in vitro'' and a fairly well characterized structure-activity relationship.

EGLU
EGLU ((2S)-α-ethylglutamic acid ) is a drug that is used in neuroscience research. It was one of the first compounds found that acts as a selective antagonist for the group II metabotropic glutamate receptors (mGluR2/3), and so has been useful in the characterization and study of this receptor subfamily In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus.

MGS-0039
MGS-0039 is a drug that is used in neuroscientific research, which acts as a potent and selective antagonist for group II of the metabotropic glutamate receptors ( mGluR2/3). It produces antidepressant and anxiolytic effects in animal studies, and has been shown to boost release of dopamine and serotonin in specific brain areas. Research has suggested this may occur through a similar mechanism as that suggested for the similarly glutamatergic drug ketamine Ketamine is a cyclohexanone-derived general anesthetic and NMDA receptor antagonist with analgesic and hallucinogenic properties, used medically for anesthesia, depression, and pain management.

LY-341,495
LY-341495 is a research drug developed by the pharmaceutical company Eli Lilly, which acts as a potent and selective orthosteric antagonist for the group II metabotropic glutamate receptors ( mGluR2/3). It is used in scientific research in several different areas, showing antidepressant effects in animal models, increasing the behavioural effects of hallucinogenic drugs in animal tests, and increasing the analgesic effects of μ-opioid agonists, as well as modulating dopamine receptor function. The 1-fluorocyclopropane analog has a superior pharmacokinetic profile and similar mGluR2/3 affinity, and making a prodrug A prodrug is a pharmacologically inactive medication or compound that, after intake, is metabolized (i.e., converted within the body) into a pharmacologically active drug.

Biphenylindanone A
Biphenylindanone A (BINA, LS-193,571) is a research agent which acts as a potent and selective positive allosteric modulator for the group II metabotropic glutamate receptor subtype mGluR2. In animal studies it showed anxiolytic and antipsychotic effects, and blocked the effects produced by the hallucinogenic drug DOB. BINA and other selective mGluR2 positive modulators have therefore been suggested as a novel class of drugs for the treatment of schizophrenia which may have superior properties to traditional antipsychotic drugs. BINA decreases cocaine self-administration Self-administration is, in its Medicine, medical sense, the process of a subject administering a Pharmacology, pharmacological substance to themself. A clinical example of this is the subcutaneous "self-injection" of insulin by a Diabetes, diabetic ... in rats, with no effect on food self-administration, and is in regard to this discrimination superior to the mGluR2/3 agonist LY-379,268.

JNJ-40411813
ADX-71149, also known as JNJ-40411813 and JNJ-mGluR2-PAM, is a selective positive allosteric modulator of the mGlu2 receptor. It is being studied by Addex Therapeutics and Janssen Pharmaceuticals for the treatment of schizophrenia. It was also researched by these companies for the treatment of anxious depression (major depressive disorder with anxiety symptoms), but although some efficacy was observed in clinical trials, it was not enough to warrant further development for this indication. , ADX-71149 is in phase II clinical trials for schizophrenia.
