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 provides a combination of (a) an antipsychotic and (b) an alpha4/beta2 (?4?2)-neuronal nicotinic receptor agonist. The invention further relates to pharmaceutical compositions comprising said combination and to the use of the combination in therapy. The invention further relates to a kit comprising the combination and use of said kit in therapy.

Abstract: Compounds, pharmaceutical compositions including the compounds, and methods of preparation and use thereof are disclosed. The compounds are N-aryl or heteroaryl azaspiroalkene/alkane compounds, prodrugs or metabolites of these compounds, or pharmaceutically acceptable salts thereof. The aryl group can be a phenyl ring or a five- or six-membered heterocyclic ring (heteroaryl). The compounds and compositions can be used to treat and/or prevent a wide variety of conditions or disorders, particularly those disorders characterized by dysfunction of nicotinic cholinergic neurotransmission, including disorders involving neuromodulation of neurotransmitter release, such as dopamine release. CNS disorders, which are characterized by an alteration in normal neurotransmitter release, are another example of disorders that can be treated and/or prevented. The compounds and compositions can also be used to alleviate pain.

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.
