专利号:US-2008145899-A1 优先权日:2004-09-17 标题 :Production of Oligosaccharides By Microorganisms 发明人:JOHNSON KARL; BYRNE NOEL J; DEFREES SHAWN 权利人:NEOSE TECHNOLOGIES INC 摘要:The present invention relates to the enzymatic synthesis of oligosaccharides, including sialylated product saccharides. In particular, it relates to the use of recombinant cells to take up low cost precursors such as glucose, pyruvate and N-actyl-glucosamine, and to synthesize activated sugar moieties that are used in oligosaccharide synthesis. The methods make possible the synthesis of many oligosaccharides using microorganisms and readily available, relatively inexpensive starting materials.

专利号:US-2024117398-A1 优先权日:2021-01-20 标 题:Production of oligosaccharides comprising ln3 as core structure in host cells 发明人:AESAERT SOFIE; BEAUPREZ JOERI; PETERS GERT; VERCAUTEREN ANNELIES 权利人:INBIOSE NV 摘要:Described is a method of producing an oligosaccharide comprising a lacto-N-triose (LN3; GlcNAc-beta1,3-Gal-beta1,4-Glc) as a core trisaccharide by cultivation with a genetically modified cell, as well as the genetically modified cell used in the method. The genetically modified cell comprises at least one nucleic acid sequence coding for a galactoside beta-1,3-N-acetylglucosaminyltransferase and a glycosyltransferase involved in the synthesis of an oligosaccharide comprising LN3 as a core trisaccharide and at least one nucleic acid sequence expressing a membrane protein. Furthermore, the present invention provides for a purification of the oligosaccharide comprising LN3 as a core trisaccharide from the cultivation.
专利号:US-2015361124-A1 优先权日:2013-01-22 标 题:Method for the solid-phase based synthesis of phosphate-bridged nucleoside conjugates 发明人:SARAC IVO; MEIER CHRIS 权利人:UNIVERSITÄT HAMBURG; UNIV HAMBURG 摘要:A method for producing phosphate-bridged nucleoside conjugates, in particular poly- or oligonucleosides. In the method, an immobilized cyclosaligenyl derivative of a nucleoside, nucleotide, poly- or oligonucleotide, poly- or oligonucleoside, or an analog thereof, is synthesized, and the subsequent reaction with a nucleophile yields the desired phosphate-bridged nucleoside conjugate, which may subsequently be released from the solid phase.

More particularly, uridine-5'-diphospho-2-deoxy-2-fluoro-galactose (UDP-2F-Gal), guanidine-5'-diphospho-2-deoxy-2-fluoro-L-fucose (GDP-2F-Fuc), uridine-51-diphospho-2-deoxy-2-fluoro-D-glucose (UDP-2F-Glu), guanosine-5'-diphospho-2-deoxy-2-fluoro-D-mannose (GDP-2F-Man), cytosine-5'-monophospho-2-deoxy-2-fluoro-D-sialic acid, and cytosine-5'-monophospho-2-deoxy-2-KDO may be employed as inhibitors of β-1,4-galactosyltransferase, α-1,3-fucosyltransferase, glucosyltransferases, N-acetylglucosaminyltransferases, (α-mannosyltransferases, α-sialyltransferases, and KDO-transferases, respectively. Synthesis of nucleotide-linked-2-deoxy-2-fluoroglycosides is achieved using either chemoenzymatic or chemical methodologies.
