  Noncompetitive antagonists of the human metabotropic glutamate receptor subtype 5 (mGluR5) have been implicated as potential therapeutics for the treatment of a variety of nervous system disorders, including pain, anxiety, and drug addiction. To discover novel noncompetitive antagonists to the mGluR5, we initiated an SAR study around the known lead compounds MPEP and M-MPEP. Our results pointed out the critical role of the para position of the two aromatic rings, which leads to inactive products and permitted the discovery of potent mGluR5 antagonists (e.g., 16, 25, 28, 34 IC50 = 13.5, 11.9, 21, 15nM, respectively).

  The present invention is directed to isotopically labeled alkyne derivative compounds, particularly 11C, 13C, 14C, 18F, 15O, 13N, 35S, 2H, and 3H labeled compounds. In particular, the present invention is directed to 11C, 13C, 14C, 18F, 15O, 13N, 35S, 2H, and 3H labeled heterocyclic alkynes and methods of their preparation. The present invention further includes a method of use of the 11C, 18F, 15O, or 13N labeled heterocyclic alkyne compounds as tracers in positron emission tomography (PET) imaging, particularly in the study of metabolic conditions in mammals, specifically conditions modulated by metabotropic glutamate receptors subtype 5 (mGluR5).
