  • Patent number: 9580434
    Abstract: Compounds, pharmaceutical compositions including the compounds, and methods of preparation and use thereof are disclosed. The compounds are amide compounds which can be prepared from certain heteroaryl carboxylic acids and certain diazabicycloalkanes. The compounds exhibit selectivity for, and bind with high affinity to, neuronal nicotinic receptors of the ?4?2 subtype in the central nervous system (CNS). The compounds and compositions can be used to treat and/or prevent a wide variety of conditions or disorders, particularly CNS disorders. The compounds can: (i) alter the number of nicotinic cholinergic receptors of the brain of the patient, (ii) exhibit neuroprotective effects, and (iii) when employed in effective amounts, not result in appreciable adverse side effects (e.g. side effects such as significant increases in blood pressure and heart rate, significant negative effects upon the gastrointestinal tract, and significant effects upon skeletal muscle).

  • Patent number: 8541447
    Abstract: 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 ?7 nAChR subtype, and are useful towards modulating neurotransmission and the release of ligands involved in neurotransmission.
