标 题 :Process for regenerating noble metal catalyst for the synthesis of hydrogen peroxide according to the anthraquinone process
发明人:SCHREYER GERD; THEISSEN FERDINAND; WEIBERG OTTO; WEIGERT WOLFGANG
权利人:DEGUSSA
摘要:In situ regeneration of noble metal catalysts for the synthesis of hydrogen peroxide by the anthraquinone process is provided by employing as the working solution coming from the extraction or desorption step and being introduced into the hydrogenation step a solution which contains at least 250 mg/liter of hydrogen peroxide, to thereby completely regenerate the noble metal catalyst by full capacity of the hydrogenation step.

标题:Modulation of prostaglandin/cyclooxygenase metabolic pathways
发明人:WUELFERT ERNST
权利人:HUNTER FLEMING LTD
摘要:A variety of diseases and disorders associated with the metabolic pathways involved in the activities of cyclooxygenase and the synthesis of prostaglandins, for example type 2 diabetes mellitus and its sequelae, ischemic vascular diseases, pain associated with inflammation, inflammatory skin conditions, spinal cord injury, peripheral neuropathy, multiple sclerosis, inflammatory bowel disease and rheumatoid arthritis, as well as various types of cancer may be treated or prevented by the use of an agent which selectively enhances production of 15-deoxy-prostaglandin J2. The compounds are 7-hydroxy-steroids or condensed indoles.

摘要:This invention is directed to novel crystalline solvates of the ( S )-P diastereomer of the anti- HCV nucleoside phosphoroamidate, (2 S )-neopentyl 2-((((2 R ,3 R ,4 R ,5 R )-5-(2-amino-6- methoxy-9H-purin-9-yl)-3,4-dihydroxy-4-methyltetrahydrofuran-2-yl)methoxy)(naphthalen- l-yloxy)phosphorylamino)propanoate (also referred to as INX-08189 or IÎ?Χ-189), and to a recrystallization method for separating the two diastereomers of INX-08189. In addition, this application relates to a novel stereoselective method for the preparation of either of the two diastereomers, and to the novel synthetic intermediates used in this stereoselective synthesis. The invention also relates to the use of the crystalline solvates to increase the liver exposure of 2'-C-methyl guanosine triphosphate from an oral dose.
