Abstract: The present invention relates to the stereospecific synthesis of (R)-5-((E)-2-pyrrolidin-3-ylvinyl)pyrimidine, its 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 compound) or to another pharmaceutically acceptable salt form.

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).
Abstract: The present invention relates to dexmecamylamine and the use of dexmecamylamine, substantially free of exo-R-mecamylamine, in the treatment of bladder disorders, including overactive bladder.
Abstract: The present invention relates to compounds that bind to and modulate the activity of neuronal nicotinic acetylcholine receptors, to processes for preparing these compounds, to pharmaceutical compositions containing these compounds, and to methods of using these compounds for treating a wide variety of conditions and disorders, including those associated with dysfunction of the central nervous system (CNS).
