Abstract: The present invention provides 4-[1-Aryl-imidazol-4-ylethynyl]-2-alkyl-pyridine and 1-heteroaryl-imidazol-4-ylethynyl]-2-alkyl-pyridine derivatives and pharmaceutically acceptable salts thereof for the treatment or prevention of disorders mediated in full or in part by metabotropic glutamate receptor 5. These disorders include, e.g. acute, traumatic and chronic degenerative processes of the nervous system, such as Alzheimer's disease, senile dementia, Parkinson's disease, Huntington's chorea, amyotrophic lateral sclerosis and multiple sclerosis, psychiatric diseases, such as schizophrenia and anxiety, depression, pain and drug dependency.

Abstract: The present invention relates to compounds of formulae 1

Abstract: Novel imidazole derivatives are disclosed. These compounds have a good affinity to the NMDA (N-methyl-D-aspartate)-receptor subtype selective blockers, which have a key function in modulating neuronal activity and plasticity which makes them key players in mediating processes underlying development of CNS as well as learning and memory formation. These compounds are useful in the control or treatment of diseases mediated by this receptor.
