Chemical switch of a metabotropic glutamate receptor 2 silent allosteric modulator into dual metabotropic glutamate receptor 2/3 negative/positive allosteric modulators.

Journal of Medicinal Chemistry, 2010
Using an mGluR2 FRET-based binding assay, binders of the transmembrane region devoid of functional activity were identified. It is reported that slight chemical modifications of these SAMs can dramatically change activity of the resulting analogues without altering their affinities.

Lack of effect of LY314582 (a group 2 metabotropic glutamate receptor agonist) on phencyclidine-induced locomotor activity in metabotropic glutamate receptor 2 knockout mice.

European Journal of Pharmacology, 2000
In metabotropic glutamate receptor 2 (mGlu(2)) knockout mice, the group 2 metabotropic glutamate receptor agonist LY314582 (20 mg/kg, i.p.), a racemate of LY354740, inhibits neither spontaneous nor phencyclidine (PCP)-induced (2.5 mg/kg, s.c.) locomotor activity.

Positive allosteric modulators of the metabotropic glutamate receptor 2 for the treatment of schizophrenia

Expert Opinion on Therapeutic Patents, 2009
Normalization of excessive glutamate neurotransmission through activation of the metabotropic glutamate receptor 2 (mGluR2) represents a novel and promising approach for the treatment of schizophrenia. This strategy has gained support through the evaluation of dual mGluR2/3 agonists that act directly at the glutamate (orthosteric) binding site ...

Progress in the developement of positive allosteric modulators of the metabotropic glutamate receptor 2.

Current Medicinal Chemistry, 2011
The metabotropic glutamate type 2 (mGlu2) receptor is a G-protein coupled receptor (GPCR) expressed on presynaptic nerve terminals where it negatively modulates glutamate and GABA release. Mixed mGlu2/mGlu3 orthosteric agonists such as LY354740 have shown activity in a range of preclinical animal models of anxiety and schizophrenia.

Metabotropic glutamate receptor 2/3 immunoreactivity in the developing rat cerebellar cortex

The Journal of Comparative Neurology, 1999
In adult rat cerebellar cortex, the metabotropic glutamate receptors (mGluRs) 2 and 3 (mGluR2/3) are present in somata, dendrites, and terminals of Golgi cells as well as in presumed glial processes (Ohishi et al. [1994], Neuron 13:55-66). In the present study, spatiotemporal changes in immunostaining for mGluR2/3 were examined in postnatal rat ...

Aberrant expression of metabotropic glutamate receptor 2 in the vulnerable neurons of Alzheimer’s disease

Acta Neuropathologica, 2004
Selective neuronal dysfunction and degeneration are defining features of Alzheimer's disease (AD). While the exact mechanism(s) contributing to this selective neuronal vulnerability remains to be elucidated, we hypothesized that the differential expression of metabotropic glutamate receptors (mGluRs) may play a key role in this process since the ...

Positive allosteric modulators of the metabotropic glutamate receptor subtype 2 (mGluR2).

Current Topics in Medicinal Chemistry, 2005
This article describes recent medicinal chemistry progress toward selective potentiators of the metabotropic glutamate receptor 2 (mGluR2). Groups at Lilly and Merck have identified new classes of potentiators that exhibit selectivity for mGluR2 over the seven other subtypes of mGluRs.

LocaliZation of metabotropic glutamate receptor type 2 in the human brain

Neuroscience, 1999
Metabotropic glutamate receptors are a heterogeneous family of G-protein-coupled receptors that are linked to multiple second messenger systems to regulate neuronal excitability and synaptic transmission. To elucidate the physiological role of these receptors in human central nervous system function and dysfunction at the receptor protein level ...

Activation of the extracellular signal‐regulated kinase 2 by metabotropic glutamate receptors

European Journal of Neuroscience, 1999
AbstractActivation of metabotropic glutamate receptors (mGluRs) leads to modulation of a variety of second messenger pathways probably including the mitogen‐activated protein kinase (MAPK) extracellular signal‐regulated protein kinases (ERK). MAPK play a key role in the control of cellular responses to changes in the external environment by regulating ...
