LY-379,268 is a drug that is used in neuroscience research, which acts as a potent and selective agonist for the group II metabotropic glutamate receptors (mGluR2/3).

It is derived from the older mGluR group II agonist eglumegad, [1] and led on to the development of the more potent compound LY-404,039, [2] but is still widely used in research itself. LY-379,268 has sedative, neuroprotective, anti-addictive and anticonvulsant effects in animals, [3] [4] [5] and blocks the effects of PCP and DOI, [6] [7] [8] [9] [10] which has led to research into LY-379,268 and similar compounds as antipsychotic drugs for the treatment of schizophrenia in animals. [11] [12]

There are inconsistent findings about an additional activity as a dopamine D2 receptor partial agonist. [13] [14]

<span class="mw-page-title-main">Metabotropic glutamate receptor</span> Type of glutamate receptor

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.

<span class="mw-page-title-main">Metabotropic glutamate receptor 1</span> Mammalian protein found in humans

The glutamate receptor, metabotropic 1, also known as GRM1, is a human gene which encodes the metabotropic glutamate receptor 1 (mGluR1) protein.

<span class="mw-page-title-main">Metabotropic glutamate receptor 2</span> Mammalian protein found in humans

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.

<span class="mw-page-title-main">Metabotropic glutamate receptor 3</span> Mammalian protein found in humans

Metabotropic glutamate receptor 3 (mGluR3) is an inhibitory Gi/G0-coupled G-protein coupled receptor (GPCR) generally localized to presynaptic sites of neurons in classical circuits. However, in higher cortical circuits in primates, mGluR3 are localized post-synaptically, where they strengthen rather than weaken synaptic connectivity. In humans, mGluR3 is encoded by the GRM3 gene. Deficits in mGluR3 signaling have been linked to impaired cognition in humans, and to increased risk of schizophrenia, consistent with their expanding role in cortical evolution.

<span class="mw-page-title-main">Metabotropic glutamate receptor 5</span> Mammalian protein found in humans

Metabotropic glutamate receptor 5 is an excitatory Gq-coupled G protein-coupled receptor predominantly expressed on the postsynaptic sites of neurons. In humans, it is encoded by the GRM5 gene.

<span class="mw-page-title-main">AMN082</span> Chemical compound

AMN082 is a selective metabotropic glutamate receptor 7 (mGluR7) allosteric agonist. It mimics the effect of glutamate. AMN082 is the first selective mGluR7 agonist and has expanded the potential array of research opportunities on the effects of mGluR7 in the central nervous system.

<span class="mw-page-title-main">MTEP</span> Chemical compound

3-( ethynyl)pyridine (MTEP) is a research drug that was developed by Merck & Co. as a selective allosteric antagonist of the metabotropic glutamate receptor subtype mGluR5. Identified through structure-activity relationship studies on an older mGluR5 antagonist MPEP, MTEP has subsequently itself acted as a lead compound for newer and even more improved drugs.

<span class="mw-page-title-main">Pomaglumetad</span> Drug, used as a treatment for schizophrenia

Pomaglumetad (LY-404,039) is an amino acid analog drug that acts as a highly selective agonist for the metabotropic glutamate receptor group II subtypes mGluR2 and mGluR3. Pharmacological research has focused on its potential antipsychotic and anxiolytic effects. Pomaglumetad is intended as a treatment for schizophrenia and other psychotic and anxiety disorders by modulating glutamatergic activity and reducing presynaptic release of glutamate at synapses in limbic and forebrain areas relevant to these disorders. Human studies investigating therapeutic use of pomaglumetad have focused on the prodrug LY-2140023, a methionine amide of pomaglumetad (also called pomaglumetad methionil) since pomaglumetad exhibits low oral absorption and bioavailability in humans.

<span class="mw-page-title-main">LY-307,452</span> Chemical compound

LY-307,452 is a drug used in neuroscience research, which was among the first compounds found that acts as a selective antagonist for the group II metabotropic glutamate receptors (mGluR2/3), and was useful in early studies of this receptor family, although it has largely been replaced by newer drugs such as LY-341,495. Its molecular formula is C21H25NO4

<span class="mw-page-title-main">HYDIA</span> Chemical compound

HYDIA is a drug that is used in neuroscience research, which acts as a potent and selective antagonist for the group II metabotropic glutamate receptors (mGluR2/3). It has been useful in the mapping of the group II mGluR receptor proteins and their molecular modeling. HYDIA is similar in structure to group II mGluR agonists such as eglumetad and pomaglumetad, but the addition of the 3-hydroxy group reverses the activity to a competitive antagonist. Other derivatives such as the 3-benzyloxy ether are more potent antagonists than HYDIA itself.

CECXG (3'-ethyl-LY-341,495) is a research drug which acts as a potent and selective antagonist for the group II metabotropic glutamate receptors (mGluR2/3), with reasonable selectivity for mGluR3. While it is some five times less potent than LY-341,495 at mGluR3, it has 38x higher affinity for mGluR3 over mGluR2, making it one of the few ligands available that is able to distinguish between these two closely related receptor subtypes.

RO-4491533 is a drug developed by Hoffmann-La Roche which acts as a potent and selective negative allosteric modulator for group II of the metabotropic glutamate receptors (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.

It has anticonvulsant effects in animal studies, and reduces self-administration of various addictive drugs.
