标 题:Endo-S2 mutants as glycosynthases, method of making and use for glycoengineering of glycoproteins
发明人：WANG LAI-XI; YANG QIANG; LI TIEZHENG; TONG XIN
权利人:UNIV MARYLAND
摘要:The present invention provides for recombinant Endo-S2 mutants (named Endo-S2 glycosynthases) that exhibit reduced hydrolysis activity and increased transglycosylation activity for the synthesis of glycoproteins wherein a desired sugar chain is added to a fucosylated or nonfucosylated GlcNAc-IgG acceptor. As such, the present invention allows for the synthesis and remodeling of therapeutic antibodies thereby providing for certain biological activities, such as, prolonged half-life time in vivo, less immunogenicity, enhanced in vivo activity, increased targeting ability, and/or ability to deliver a therapeutic agent.

权利人:LIOTTA DENNIS C; LI YONGFENG
摘要:This invention provides highly regioselective and stereoselective processes for preparing synthetic nucleosides. A process for the preparation of synthetic nucleosides is provided that comprises a) preparing a bicycloamide derivative, b) reacting the bicycloamide derivative with a nucleic acid base or heterocyclic base or salt thereof in the presence of a transition metal catalyst to form a cyclopentenecarboxamide, and c) cleaving a carboxamide group from the cyclopentenecarboxamide to form the synthetic nucleoside. The processes according to the invention can be used for the synthesis of a variety of anti-viral agents, including Abacavir, Carbovir, and Entecavir, as well as derivatives thereof.
