摘要:
This invention relates to crystalline salts of naloxone and of naltrexone and their use as opioid antagonists. The crystalline salts of the invention include naloxone saccharinate, naltrexone succinate and a methanol solvate of naltrexone succinate. A drug-in-adhesive transdermal patch containing the opioid analgesic fentanyl or an analog thereof and a crystalline salts of naloxone or naltrexone is disclosed. Also disclosed is a method of treating pain, such as acute, chronic or intermittent pain, by applying a drug-in-adhesive transdermal patch of the invention to the skin of a patient in need thereof.
摘要:
Disclosed is the oxidation of uronic acids, such as galacturonic acid, to the corresponding aldaric acids, such as galactaric acid, under neutral or acidic conditions. Use is made of a supported gold catalyst. The oxidation occurs in good selectivity and yield, under unexpectedly mild conditions. A source of galacturonic acids is pectins, such as from sugar beet pulp.

The invention relates to a purified Isometheptene compound comprising the structure according to Formula (I), (Formula (I)) or a hydrochloride, or a pharmaceutically acceptable addition salt thereof. In particular, the disclosure relates to the synthesis, purification and characterization of an Isometheptene isomer mucate crystal 2, wherein the Isometheptene isomer 2 is stereochemically characterized as (R)-enantiomer, respectively. The Isometheptene (R)-enantiomer activity indicates a selective centrally acting selective ligand for Imidazoline subtype 1 (I1) receptor sites; and more specifically, the disclosure provides an antihypertensive composition for treatment of migraine and other neurovascular or neurogenic pain from abdominal distress. (R)-Isometheptene enantiomer or isomer 2 may be an anti-hypertensive agent with lower side effects than the racemate form. Therefore (R)-Isometheptene is believed to be effective against episodic tension-type headaches (ETTH). The (R)-Isometheptene enantiomer or isomer 2 is believed to effectively lower blood pressure, used alone or together with other headache ameliorating drugs. Methods of synthesis and treatment are described. Regarding (R)- Isometheptene crystals data of X-ray crystallography are presented.

摘要:
Stable and non-hygroscopic zinc salts of carnitines with galactaric acid are disclosed, which advantageously lend themselves to the preparation of solid compositions suitable to be orally administered. The processes for preparing these salts are also disclosed.
摘要:
Stable, non-hygroscopic salts of L(-)carnitine and alkanoyl L(-)carnitines with mucic acid of formula (I) are disclosed wherein the molar ratio between the carnitine moiety and mucic acid is 2:1. A process for producing the salts and solid orally administrable compositions containing same are also disclosed.
摘要:
Amphipathic amine-esters derived from anhydropentitols are prepared through a short sequence of synthetic steps. The process is initiated by the esterification of an anhydropentitol with a fatty acid chloride or a lipase enzyme to form anhydropentitol fatty acid esters, preferably leaving at least one free hydroxyl. The free hydroxyl group(s) are then sulfonated, forming sulfonated anhydropentitol fatty acid esters. The sulfonyl moiety on the sulfonated anhydropentitol fatty acid esters are then subject to nucleophilic displacement by a hydrophilic moiety, illustrated by a primary amine such as AEE or AEEA. The synthetic pathway is efficient and affords modest to high yields of target amphiphilic compounds, which are useful at least as surfactants and plasticizer substitutes for petroleum derived compounds.
