  • Patent number: 8114889
    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 heteoraryl carboxylic acids and certain diazabicycloalkanes. The compounds exhibit selectivity for, and bind with high affinity to, neuronal nicotinic receptors of the a4?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).

  • Publication number: 20110071188
    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 C14 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), partidularly the ?7 nAChR subtype, and are useful towards modulating neurotransmission and the release of ligands involved in neurotransmission.

  • Patent number: 7897611
    Abstract: Patients susceptible to or suffering from disorders, such as central nervous system disorders, which are characterized by an alteration in normal neurotransmitter release, such as dopamine release (e.g., Parkinsonism, Parkinson's Disease, Tourette's Syndrome, attention deficient disorder, or schizophrenia), are treated by administering a compound of Formulas 1 or 2, as described herein. The compounds of Formulas 1 and 2 are also useful for treating pain, and treating drug addiction, nicotine addiction, and/or obesity. The compounds can exist as individual stereoisomers, racemic mixtures, diastereomers and the like.

  • Publication number: 20100197720
    Abstract: The present invention relates to amide and urea derivatives of heteroaryl-substituted diazatricycloalkanes, pharmaceutical compositions including the compounds, methods of preparing the compounds, and methods of treatment using the compounds. More specifically, the methods of treatment involve modulating the activity of the ?7 nAChR subtype by administering one or more of the compounds to treat or prevent disorders mediated by the ?7 nAChR subtype. The diazatricycloalkanes typically consist of a 1-azabicyclooctane fused to pyrrolidine ring. The substituent heteroaryl groups are 5- or 6-membered ring heteroaromatics, such as 3-pyridinyl and 5-pyrimidinyl moieties, which are attached directly to the diazatricycloalkane. The secondary nitrogen of the pyrrolidine moiety is substituted with an arylcarbonyl (amide type derivative) or an arylaminocarbonyl (N-arylcarbamoyl) (urea type derivative) group.
