专利号:WO-9747579-A1 优先权日:1996-06-10 标题:Methods for synthesis of high purity carboxylic and fatty acids 发明人:AHMED IRSHAD 权利人:RENEWABLE ENERGY DEV CORP 摘要:A method for separating a carboxylic or fatty acid from a reaction mixture of water-soluble components, including the steps of: (a) esterifying the acid with an alcohol to produce a water insoluble ester; (b) separating the water insoluble ester from the reaction mixture; (c) hydrolyzing the water insoluble ester to yield the acid and the alcohol; and (d) separating the acid from the alcohol.
专利号:US-2004053999-A1 优先权日:1997-09-17 标题 :Novel compounds and methods for synthesis and therapy 发明人:BISCHOFBERGER NORBERT W; DAHL TERRENCE C; HITCHCOCK MICHAEL J M; KIM CHOUNG U; LEW WILLARD; LIU HONGTAO; MILLS ROGER G; WILLIAMS MATTHEW A 摘要:Novel compounds are described. The compounds generally comprise an acidic group, a basic group, a substituted amino or N-acyl and a group having an optionally hydroxylated alkane moiety. Pharmaceutical compositions comprising the inhibitors of the invention are also described. Methods of inhibiting neuraminidase in samples suspected of containing neuraminidase are also described. Antigenic materials, polymers, antibodies, conjugates of the compounds of the invention with labels, and assay methods for detecting neuraminidase activity are also described.
