Methoxy-PEPy

• Description:

  Methoxy-PEPy is a potent and highly selective mGlu5 receptor antagonist with IC50 of 1 nM. IC50 value: 1 nM [1] Target: mGlu5R inhibitor Administration of [3H]methoxy-PEPy (50 microCi/kg i.v.) to mGlu5 receptor-deficient mice revealed binding at background levels in forebrain, whereas wild-type mice exhibited 14-fold higher binding in forebrain relative to cerebellum [2]. The calcium transients stimulated by these agonists were potently inhibited by reference allosteric mGlu5 antagonists - 2-methyl-6- (phenylethynyl) pyridine (MPEP), 3-[ (2-methyl-1,3-thiazol-4-yl) ethynyl]pyridine (MTEP) and 3-methoxy-5- (pyridine-2-ylethynyl) pyridine (methoxy-PEPy) (IC (50) ranges: 0.8-66 nM) [3].
