专利号:US-6117992-A 优先权日:1996-08-26 标题 :Reagents and process for synthesis of oligonucleotides containing phosphorodithioate internucleoside linkages 发明人:IYER RADHAKRISHNAN P 权利人:HYBRIDON INC 摘要:The invention provides new methods for synthesizing oligonucleotides containing at least one, and preferably all phosphorodithioate internucleoside linkages with less than 5% phosphoromonothioate contamination. This level of purity in the synthesis of phosphorodithoates has previously been very difficult to achieve with all existing methods. The invention further provides phosphorothioamidite nucleoside synthons comprising a sulfur protecting group that is stable under normal oligonucleotide synthesis conditions.

专利号:US-9376461-B2 优先权日:2011-06-06 标 题:Non-enzymatic synthesis of O-acetyl-ADP-ribose and analogues thereof 发明人:KOPPETSCH KARSTEN; SZCZEPANKIEWICZ BRUCE G; PERNI ROBERT B 权利人:KOPPETSCH KARSTEN; SZCZEPANKIEWICZ BRUCE G; PERNI ROBERT B; GLAXOSMITHKLINE LLC 摘要:Provided herein is a simple, one-step, non-enzymatic synthesis of O-Acetyl-ADP-ribose (OAADPR) from NAD and sodium acetate in acetic acid. The extension of this reaction to other carboxylic acids, demonstrates that the reaction between NAD, and NAD analogs produces mixtures of the corresponding 2′- and 3′-carboxylic esters. Included are O-carboxyl-ADP-ribose compounds and corresponding methods of synthesis (e.g., O-propionyl-ADP-ribose, O-succinyl-ADP-ribose, O-malonyl-ADP-ribose), as well as non-adenosine nucleoside compounds.
专利号:US-11059849-B2 优先权日:2014-09-02 标题 :Modified nucleotides for synthesis of nucleic acids, a kit containing such nucleotides and their use for the production of synthetic nucleic acid sequences or genes 发明人:YBERT THOMAS; GARIEL SYLVAIN 权利人:DNA SCRIPT 摘要:A modified nucleotide, intended for the synthesis of long chain nucleic acids by enzymatic processes, comprising a “naturalâ€? nitrogenous base or a natural nitrogenous base analogue, a ribose or deoxyribose carbohydrate, and at least one phosphate group, characterized in that said nucleotide comprises at least one R group, termed the modifier group, carried by said nitrogenous base or analogue and/or by the oxygen in position 3′ of the ribose or deoxyribose molecule, making it possible to block the polymerization of said nucleotide and/or to allow the interaction of said nucleotide with another molecule, such as a protein, during the nucleic acid synthesis, R comprising at least one functional terminal group.
