Non-distillative Process for Manufacturing High Purity Amphetamines
摘要:
The invention provides a non-distillative process for manufacturing amphetamine and substituted amphetamines, comprising obtaining a highly pure phosphoramidate compound, converting the highly pure phosphoramidate compound to an amphetamine sulfate compound, concentrating the amphetamine sulfate compound in isopropanol, and then salting out the amphetamine compound directly to obtain an amphetamine salt, the amphetamine salt selected from amphetamine saccharate, amphetamine sulfate, amphetamine aspartate, alkyl-amphetamine saccharate, alkyl-amphetamine sulfate, alkyl-amphetamine aspartate, aryl-amphetamine saccharate, aryl-amphetamine sulfate, aryl-amphetamine aspartate, and mixtures thereof.
Compounds and pharmaceutically acceptable salts of the compounds are disclosed, wherein the compounds have the structure of Formula I
as defined herein. Corresponding pharmaceutical compositions, methods of treatment, methods of synthesis, and intermediates are also disclosed.
The present invention provides an ion pair compound of the formula [narcotic]
+
[A]
−
, wherein [narcotic]
+
represents at least one cation of at least one narcotic agent or one or more stereochemical isomers thereof and [A]
−
represents at least one anion of at least one NSAID or one or more stereochemical isomers thereof. An example of the ion pair compound is propoxyphene diclofenate. The ion pair compounds, or their pharmaceutical compositions, are useful in methods of treating a wide variety of conditions that indicate analgesics, anti-inflammatory agents, or both. Under the conditions prescribed for their use, the ion pair compounds exhibit poor or complete insolubility but excellent chemical stability in low pH environments, such as those found in the stomach. The ion pair compounds readily dissolve and dissociate in higher pH environments such as the small intestine to release the constituent narcotic and NSAID.
The present disclosure relates to compounds useful as inhibitors of the enzyme Fatty Acid Amide Hydrolase (FAAH). The disclosure also provides pharmaceutically acceptable compositions comprising the compounds of the disclosure and methods of using the compositions in the treatment or prevention of various disorders. Compounds of the invention are described in Table 1.
The invention provides PDE9-inhibiting compounds of Formula (I),
and pharmaceutically acceptable salts thereof, wherein R
1
, R
