Abstract: The present invention relates to the stereospecific synthesis of (R)-5-((E)-2-pyrrolidin-3-yl)pyrimidine, novel salt forms, and novel polymorphic forms of these salts.
Abstract: Patients susceptible to or suffering from conditions and disorders, such as central nervous system disorders, are treated by administering to a patient in need thereof compositions that are hydroxybenzoate salts of E-metanicotine-type compounds. The formation of hydroxybenzoate salts of the E-metanicotine compounds is also useful in purifying the E-metanicotine compounds, as the hydroxybenzoate salts tend to crystallize out, leaving impurities such as Z-metanicotine compounds, and compounds where the double bond has migrated, in solution. If desired, the hydroxybenzoate salts can be converted to either the free base (the E-metanicotine) or to another pharmaceutically acceptable salt form.

Abstract: Novel vinylazacycloalkane compounds of Formula (I) are disclosed. The compounds are ligands of various nAChRs. The compounds and their pharmaceutically acceptable salts can be used to prepare pharmaceutical compositions and/or medicaments intended to prevent or treat disorders associated with dysfunction of nAChRs, especially within the central nervous system or the gastrointestinal system. Examples of types of disorders that can be treated include neurodegenerative disorders, including central nervous system disorders such as Alzheimer's disease, cognitive disorders, motor disorders such as Parkinson's disease, drug addiction, behavioral disorders and inflammatory disorders within the gastrointestinal system. The compounds can also serve as analgesics in the treatment of acute, chronic or recurrent pain.

Abstract: A novel scalable synthesis for the preparation of 7-(3-pyridinyI)-1,7-diazaspiro[4.4)nonane has been developed, and 7-(3-pyridinyl)-1,7-diazaspiro[4.4]nonane salts have been formed with succinic acid and oxalic acid. Additionally, 7-(3-pyridinyl)-1,7-diaza-spiro[4.4]nonane has been separated into its stereoisomers via resolution with L and D di-p-toluoyltartaric acids, giving (R)- and (S)-7-(3-pyridinyl)-1,7-diazaspiro[4.4]nonane of high enantiomeric purity. Numerous solid salts of the resulting (R)- and (S)-7-(3-pyridinyl)-1,7-diazaspiro[4.4}nonane have been prepared. Methods for the preparation of the racemic and enantiomeric salts, pharmaceutical compositions comprising such salts, and uses thereof are disclosed. The salts can be administered to patients susceptible to or suffering from conditions and disorders, such as central nervous system disorders, to treat and/or prevent such disorders.

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.
