Compounds of Formula I or Formula II wherein R1, X and Ar are as described in the specification, pharmaceutically-acceptable salts thereof, processes for preparing them, pharmaceutical compositions containing them and their use in therapy, especially for treatment of conditions associated with reductions in nicotinic transmission.

The invention provides compounds of Formula I: These compounds may be in the form of pharmaceutical salts or compositions, may be in pure enantiomeric form or racemic mixtures, and are useful in pharmaceuticals used to treat diseases or conditions in which α7 nAChR is known to be involved.

The present invention discloses compounds of formula (I) any of its enantiomers or any mixture thereof, isotopes thereof or a pharmaceutically acceptable salt thereof, wherein n is 1, 2 or 3; m is 0, 1 or 2; R represents hydrogen, alkyl, cycloalkyl, cycloalkylalkyl or aralkyl; and R<1 >represents aminophenyl; nitrophenyl; hydroxyphenyl, alkoxyphenyl; a monocyclic 5 to 6 membered heterocyclic group which may be substituted one or more times with substituents or R<1 >represents a bicyclic heterocyclic group, composed of 5 to 6 membered monocyclic heterocyclic group fused to a benzene ring, and which may be substituted one or more times with substituents. The compounds of the invention are useful as nicotinic ACh receptor ligands.

The present invention relates to 3-substituted-2-(arylalkyl)-1-azabicycloalkanes, methods of preparing the compounds and methods of treatment using the compounds. The azabicycloalkanes generally are azabicycloheptanes, azabicyclooctanes, or azabicyclononanes. The aryl group in the arylalkyl moiety is a 5- or 6-membered ring heteroaromatic, preferably 3-pyridinyl and 5-pyrimidinyl moieties, and the alkyl group is typically a C1-4 alkyl. The substituent at the 3-position of the 1 -azabicycloalkane is a carbonyl group-containing moiety, such as an amide, carbamate, urea, thioamide, thiocarbamate, thiourea or similar functionality. The compounds exhibit activity at nicotinic acetylcholine receptors (nAChRs), particularly the α7 nAChR subtype, and are useful towards modulating neurotransmission and the release of ligands involved in neurotransmission. Methods for preventing or treating conditions and disorders, including central nervous system (CNS) disorders, which are characterized by an alteration in normal neurotransmission, are also disclosed. Also disclosed are methods for treating inflammation, autoimmune disorders, pain and excess neovascularization, such as that associated with tumor growth.
