Abstract: In one aspect, the invention relates to bicyclic MGluR5 positive allosteric modulators, for example 6-(phenylethynyl)-3,4-dihydroisoquinolin-1(2H)-one, derivatives thereof, and related compounds, which are useful as positive allosteric modulators of the metabotropic glutamate receptor subtype 5 (mGluR5); synthetic methods for making the compounds; pharmaceutical compositions comprising the compounds; and methods of treating neurological and psychiatric disorders associated with glutamate dysfunction using the compounds and compositions. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

Abstract: Provided is a method of treating conditions and disorders for which full mGluR5 antagonists are potentially effective, such as, e.g., anxiety, epilepsy, schizophrenia and other psychotic disorders, Parkinson's disease, addictive disorders, and the like in a subject in need of such treatment, comprising administration to such subject of a therapeutically effective amount of a partial, non-competitive mGluR5 antagonist compound of the invention. Specific examples of partial MgluR5 antagonists provided include those compounds having the formula: wherein: Z is, independently N or —CH—, provided that one, and only one Z is N; R is halogen (e.g., Br, F and the like), alkyl (e.g., methyl), alkenyl (e.g., CH?CH2, aryl (e.g., phenyl), heterocyclic (e.g., thiophenyl).

Abstract: In one aspect, the invention relates to compounds, including phenylethynylbenzamide derivatives, cycloalkylethynylbenzamide derivatives, styrylbenzamide derivatives, 4-(3-phenyl-1,2,4-oxadiazol-5-yl)benzamide derivatives, 4-(pyridinylethynyl)benzamide derivatives, and N1-phenylterephthalamide derivatives, which are useful as positive allosteric modulators of the metabotropic glutamate receptor subtype 5 (mGluR5); synthetic methods for making the compounds; pharmaceutical compositions comprising the compounds; and methods of treating neurological and psychiatric disorders associated with glutamate dysfunction using the compounds and compositions. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
