专利号:US-6479549-B2 优先权日:2000-02-28 标 题:Carnosic acid derivatives for promoting synthesis of nerve growth factor 发明人:KOSAKA KUNIO; MIYAZAKI TOSHITSUGU; YOKOI TOSHIO 权利人:NAGASE & CO LTD 摘要:A novel carnosic acid derivative for promoting the synthesis of nerve growth factor (NGF), a composition comprising the carnosic acid derivative as an effective ingredient, as well as, a method of promoting the synthesis of NGF comprising administering an effective amount of the carnosic acid derivative as an effective ingredient to a subject requiring such promotion. The carnosic acid derivative, composition and method according to the present invention can safely and efficiently promote the production of NGF in the living body, without being accompanied by a side effect such as a loss of a quantitative balance of hormones in the living body.
专利号:US-5139940-A 优先权日:1989-10-26 标题 :Activation compounds and methods of synthesis of activation compounds 发明人:ISAACS STEPHEN T; CIMINO GEORGE D; METCHETTE KENNETH C; TESSMAN JOHN W 权利人:ISAACS STEPHEN T; CIMINO GOERGE D; METCHETTE KENNETH C; TESSMAN JOHN W 摘要:The invention is directed to isopsoralen compound compositions that contain a variety of substitutions which yet permit their binding to nucleic acid polymers. Reaction conditions that activate these bound isopsoralens results in covalent crosslinking to the nucleic acid polymers. The resultant complex is inhibited from being a template for the template-directed enzymatic synthesis of a complementary nucleic acid polymer. Beside the isopsoralens compositions, the invention includes their synthesis, the nucleic acid complex production and detection, and the above inhibitory method of use of the isopsoralens.

专利号:US-7888337-B2 优先权日:2007-08-31 标 题 :Synthesis of oseltamivir containing phosphonate congeners with anti-influenza activity 发明人:WONG CHI-HUEY; FANG JIM-MIN; SHIE JIUN-JIE; CHENG YIH-SHYUN EDMOND; JAN JIA-TSRONG 权利人:ACADEMIA SINICA 摘要:Novel phosphonate compounds are described. The compounds have activity as neuraminidase inhibitors against wild-type and H274Y mutant of H1N1 and H5N1 viruses. The present disclosure also provides an enantioselective synthetic route to known neuraminidase inhibitors oseltamivir and the anti-flu drug Tamiflu®, as well as novel phosphonate compounds, via D-xylose. Another efficient and flexible synthesis of Tamiflu and the highly potent neuraminidase inhibitor Tamiphosphor was also achieved in 11 steps and >20% overall yields from the readily available fermentation product (1S-cis)-3-bromo-3,5 -cyclohexadiene-1,2-diol. Most of the reaction intermediates were obtained as crystals without tedious purification procedures. The key transformations include an initial regio- and stereoselective bromoamidation of a bromoarene cis-dihydrodiol, as well as the final palladium-catalyzed carbonylation and phosphonylation.
