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: A muscarinic M1 receptor ectopic activator, such as a muscarinic M1 receptor allosteric potentiator or a muscarinic M1 receptor ectopic agonist is useful, alone or in combination with other antipsychotic agents, for treating or preventing psychosis, such as a schizophrenic disorder or psychosis in Alzheimer's disease or bipolar disorder, for enhancing cognition and for neuropathic pain.

Abstract: An mGluR4 receptor positive allosteric modulator is useful, alone or in combination with a neuroleptic agent, for treating or preventing movement disorders such as Parkinson's disease, dyskinesia, tardive dyskinesia, drug-induced parkinsonism, postencephalitic parkinsonism, progressive supranuclear palsy, multiple system atrophy, corticobasal degeneration, parkinsonian-ALS dementia complex, basal ganglia calcification, akinesia, akinetic-rigid syndrome, bradykinesia, dystonia, medication-induced parkinsonian, Gilles de la Tourette syndrome, Huntington's disease, tremor, chorea, myoclonus, tick disorder, and dystonia.

Abstract: This application relates to methods of identifying pharmacoperone agents that can restore function to a misfolded protein, such as a misfolded protein that causes disease. Also disclosed are methods of using such pharmacoperone agents to treat a disease or disorder that results from the misfolded protein.
