What is MPEP?

The Uses of MPEP

MPEP is a potent and highly selective non-competitive mGlu5a receptor antagonist (1,2). It is also a positive allosteric modulator at mGlu4 receptors.MPEP exhibits anxiolytic and antidepressant properties that may be applicable for treating schizophrenia (3).

The Uses of MPEP

A potent, subtype selective mGluR5 antagonist

The Uses of MPEP

2-Methyl-6-(2-phenylethynyl)pyridine induces pathophysiological mGluR5 signaling in Alzheimer''s disease model mice in sex-selective manner.

What are the applications of Application

MPEP hydrochloride is a selective antagonist of the mGluR5 receptor

Definition

ChEBI: 2-methyl-6-(phenylethynyl)pyridine is a methylpyridine that coinsists of 2-methylp[yridine bearing an additional phenylethynyl group at position 6. Potent and highly selective non-competitive antagonist at the mGlu5 receptor subtype (IC50 = 36 nM) and a positive allosteric modulator at mGlu4 receptors. Centrally active following systemic administration in vivo. Reverses mechanical hyperalgesia in the inflamed rat hind paw. It has a role as a metabotropic glutamate receptor antagonist and an anxiolytic drug. It is a member of methylpyridines and an acetylenic compound. It is a conjugate base of a 2-methyl-6-(phenylethynyl)pyridinium(1+). It derives from a hydride of an acetylene.

Biological Activity

Potent and highly selective non-competitive antagonist at the mGlu 5 receptor subtype (IC 50 = 36 nM) and a positive allosteric modulator at mGlu 4 receptors. Centrally active following systemic administration in vivo . Reverses mechanical hyperalgesia in the inflamed rat hind paw. Also available as part of the Group I mGlu Receptor Tocriset™ .
