摘要:
A novel scalable synthesis for the preparation of 7-(3- pyridinyI)- 1,7- diazaspiro[4.4)nonane has been developed, and7-(3-pyridinyl)-1,7-diazaspiro[4.4]nonane salts have been formed with succinic acid and oxalic acid. Additionally, 7-(3-pyridinyl)-1,7- diazaspiro[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.

摘要:
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).
摘要:
The present invention relates to (R) -3- ( (E) -2- (pyrrolidin-3-yl) vinyl) -5- (tetrahydropyran-4-yloxy) pyridine, its salt forms, and to processes for the commercial-scale production of these compounds in sufficient purity and quality for use in pharmaceutical compositions. The present invention relates also the use of this compound in the manufacture of a medicament for the treatment of CNS related disorders.
摘要:
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.
摘要:
Polymorph forms of (2S)-(4E)-N-methyl-5-[3-(5-isopropoxypyridin)yl]-4- penten-2-amine p-hydroxybenzoate, and methods for their preparation, pharmaceutical composition containing said polymorph(s) and use, are disclosed. The polymorphs 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.
