专利号:US-8084007-B2 优先权日:2004-01-30 标题 :Methods of synthesis of isotropically enriched borohydride and methods of synthesis of isotropically enriched boranes 发明人:SPIELVOGEL BERNARD; COOK KEVIN S 权利人:SPIELVOGEL BERNARD; COOK KEVIN S; SEMEQUIP INC 摘要:The invention provides new methods for the synthesis of isotopically enriched metal borohydrides, metal tetrahydroundecaborate salts, and decaborane from isotopically enriched 10 B-boric acid or 11 B-boric acid. The invention is particularly useful for synthesis of isotopically enriched sodium or lithium borohydride, MB 11 H 14 (where M is Li, Na, K, or alkylammonium), and decaborane.

专利号:US-5122601-A 优先权日:1990-12-07 标题:Synthesis of 2,3,3',4,4'-penta-o-methylsucrose 发明人:SACHINVALA NAVZER D 权利人:HAWAIIAN SUGAR PLANTERS ASSOC 摘要:A process for manipulating any polyhydroxy compound bearing two or more primary and secondary hydroxyl groups to expose only the primary hydroxyl groups, while blocking all interfering secondary hydroxyl groups as their methyl or other alkyl ethers. More particularly, the present invention relates to the synthesis of 2,3,3',4,4'-penta-O-methylsucrose by using this method.

专利号:US-2007172520-A1 优先权日:2005-11-18 标题:Immunotargeting of Nonionic Surfactant Vesicles 发明人:VANAUKER MICHAEL; PLAAS ANNA; HOOD ELIZABETH 权利人:UNIV SOUTH FLORIDA 摘要:An immunoniosmes for targeted delivery of therapeutic agents to specific tissues in a host and methods of synthesis of those niosomes. An antibody molecule having specificity for a target antigen, such as a cell surface marker or other marker differentially expressed on a target cell, is covalently coupled to a functionalized membrane constituent. In a particular embodiment the functionalized membrane constituent is polyoxyethylene sorbitan monostearate functionalized with cyanuric chloride. The niosomes of this invention thus provide a composition that enhances internalization or retention of the bioactive agent of the niosome into the cytoplasm of the cells of the target tissue by providing a high degree of target specificity. Furthermore, the membrane vesicle enhances the life of the therapeutic agent by preventing its degradation in the extracellular environment, while exhibiting lower toxicity than can occur with some liposomes. The niosomes of the present invention are thus particularly useful as vehicles for the delivery of therapeutics to specific target cells.
