摘要

This invention relates to novel 1,4-diaza-bicyclo[3.2.2]nonyl pyrimidinyl derivatives and their use in the manufacture of pharmaceutical compositions. The compounds of the invention are found to be cholinergic ligands at the nicotinic acetylcholine receptors. Due to their pharmacological profile the compounds of the invention may be useful for the treatment of diseases or disorders as diverse as those related to the cholinergic system of the central nervous system (CNS), the peripheral nervous system (PNS), diseases or disorders related to smooth muscle contraction, endocrine diseases or disorders, diseases or disorders related to neuro-degeneration, diseases or disorders related to inflammation, pain, and withdrawal symptoms caused by the termination of abuse of chemical substances. Formula (I) a stereoisomer or a mixture of its stereoisomers, or a pharmaceutically acceptable salt thereof, wherein Ar represents an indolyl group, which indolyl may optionally be substituted one or more times with substituents selected from halo, trifluoromethyl, trifl?oromethoxy, cyano, nitro, amino, alkyl, hydroxy and alkoxy.
