专利号:WO-9516049-A1 优先权日:1993-12-08 标题 :Catalytic chemo-enzymatic asymmetric synthesis of carbohydrates 发明人:WONG CHI-HUEY; SHARPLESS BARRY K 权利人:SCRIPPS RESEARCH INST; WONG CHI HUEY; SHARPLESS BARRY K 摘要:A stereoselective synthesis of carbohydrates employs two key stereoselective steps, viz. an osmium-catalyzed asymmetric dihydroxylation (AD) of an alkene to form an aldol intermediate and an aldolase-catalyzed aldol addition reaction wherein the aldol intermediate is elongated by the addition of a ketone. Moreover, ketoses having four new stereocenters can be synthesized without the use of chiral starting materials. The stereoselectivity of the asymmetric dihydroxylation (AD) reaction is determined by the cis or trans (Z or E) stereoisomeric configuration of the alkene and by the choice of AD-mix, i.e., an AD-mix-α or AD-mix-β. The stereoselectivity of the aldolase-catalyzed addition reaction is determined by the choice of aldolase and by the stereochemistry of the aldol intermediate. Four aldolases with broad substrate specificity are sufficient to produce all possible enantiomeric combinations of the two hydroxymethylene stereocenters formed during the aldol addition reaction. Accordingly, a synthetic scheme combining an osmium-catalyzed asymmetric dihydroxylation (AD) reaction and an aldolase-catalyzed aldol addition reaction enables direct access to a wide range of carbohydrate derivatives containing up to four new hydroxymethylene stereocenters.
专利号:US-5302520-A 优先权日:1990-09-25 标 题:Enzymatic synthesis of isotopically labeled carbohydrates 发明人:GOUX WARREN J 权利人:UNIV TEXAS 摘要:The present invention relates to a general method of enzymatic synthesis of isotopically labeled carbohydrates, sugars and nucleosides. Labeled citric acid cycle intermediates, amino acids and ribose mononucleotides may be rapidly and conveniently synthesized from labeled pyruvate, lactate or L-alanine. The method employs a novel nicotinamide dinucleotide regeneration system which permits use of low NADH levels. The method may be manipulated to allow labeling at a variety of carbon/hydrogen sites.

专利号:US-10675366-B2 优先权日:2016-08-12 标 题 :Imaging tumor glycolysis by non-invasive measurement of pyruvate kinase M2 发明人:BEINAT CORRINE GAYE; ALAM ISRAT SHAMIMA; JAMES MICHELLE L; GAMBHIR SANJIV S; SRINIVASAN ANANTH 权利人:UNIV LELAND STANFORD JUNIOR 摘要:The present disclosure provides a positron emission tomography (PET)-detectable 1-((2-fluoro-6-[18F]fluorophenyl)sulfonyl)-4-((4-methoxyphenyl)sulfonyl)piperazine ([18F]DASA-23) probe that can selectively bind to the pyruvate kinase variant M2 (PKM2) found in cancer cells, such as of human glioma. Given the importance of PKM2 in the regulation of tumor metabolism, there is an on-going need to non-invasively measure its expression through the development of PKM2-specific radiopharmaceuticals. Precursors useful for the synthesis of the radiolabeled [18F]DASA-23-PKM2-specific probe and related compounds, and their methods of synthesis, are provided. Since the half-life of the 18F isotope is approximately 110 min, it is advantageous for a practitioner to attach the radionuclide to the precursor shortly before administration. Therefore, a precursor compound suitable for receiving the radionuclide and capable of specifically binding to the PKM2 variant can be provided.
