  Synthesis of 2-C-branched derivatives of d-mannose: 2-C-aminomethyl-d-mannose binds to the human C-type lectin DC-SIGN with affinity greater than an order of magnitude compared to that of d-mannose

  摘要：

  2-C-Substituted branched D-mannose analogues are novel monosaccharides, readily obtained from a Kiliani-acetonation sequence on D-fructose, followed by subsequent functional group manipulation. 2-C-Azidomethyl-D-mannose and 2-C-aminomethylD-marmose bind to the C-type lectin DC-SIGN (CD209) with significantly greater affinity than mannose. In particular, 2-C-aminomethyl-D-mannose exhibits a comparative 48-fold increase in binding as determined using a surface plasmon resonance-based competition assay. DC-SIGN is an important cell-surface type II transmembrane protein that interacts with blood group antigens, endogenous glycoproteins such as ICAM-3, and also deadly pathogens such as the human immunodeficiency and hepatitis C viruses. The effective use of small compounds to block target binding by mannose-selective C-type lectins at sub-millimolar concentrations has not been shown previously; thus, these data represent a very attractive thoroughfare to novel antiviral and immunomodulatory drug development. @ 2007 Elsevier Ltd.

  酮糖上的Kiliani：d-果糖和l-山梨糖的支链碳水化合物构件

  摘要：

  经保护的支链糖内酯可通过Kiliani-丙酮化序列在容易获得的酮糖如d-果糖和l-山梨糖上获得。在两种情况下，容易结晶的二丙酮化物在产物内酯中具有2，3-顺-二醇关系。来自d-果糖的产物在C-4和C-5处的构型的有效两次转化使得能够获得来自l--糖的形式Kiliani产物。支链碳水化合物内酯作为具有功能化四元中心的同手性目标的卡隆，可能具有重要的价值。

  Three homochiral polyhydroxylated piperidines containing a quaternary carbon branch at C-2 of the heterocyclic ring, which can be considered as branched analogues of deoxymannorijimycin (DMJ), and their corresponding lactams were synthesised from readily available and versatile carbohydrate lactones containing a 2-C-hydroxymethyl branch.

• Doubly carbon-branched pentoses: synthesis of both enantiomers of 2,4-di-C-methyl arabinose and 2-deoxy-2,4-di-C-methyl arabinose using only acetonide protection

  An acetonide is the only protecting group used in the synthesis of both the enantiomers of 2,4-di-C-methyl arabinose and 2-deoxy-2,4-di-C-methyl arabinose via the enantiomeric 3-C-methyl-L-erythronolactone [from 2-C-methyl-D-ribono-lactone or D-ribose] and 3-C-methyl-D-erythronolactone [from D-tagatose Or L-ribose]. NMR studies on unprotected C-methyl arabinoses show that methyl branching significantly affects the ratios of pyranose and furanose forms present in aqueous Solution. (C) 2009 Elsevier Ltd.

• <i>C</i>-Branched Iminosugars: α-Glucosidase Inhibition by Enantiomers of isoDMDP, isoDGDP, and isoDAB–<scp>l</scp>-isoDMDP Compared to Miglitol and Miglustat

  The Ho crossed aldol condensation provides access to a series of carbon branched iminosugars as exemplified by the synthesis of enantiomeric pairs of isoDMDP, isoDGDP, and isoDAB, allowing comparison of their biological activities with three linear isomeric natural products DMDP, DGDP, and DAB and their enantiomers. L-IsoDMDP [(2S,3S,4R)-2,4-bis(hydroxymethyl)pyrrolidine-3,4-diol], prepared in 11 steps in an overall yield of 4596 from D-lyxonolactone, is a potent specific competitive inhibitor of gut disaccharidases [K-i 0.081 mu M for rat intestinal maltase] and is more effective in the suppression of hyperglycaemia in a maltose loading test than miglitol, a drug presently used in the treatment of late onset diabetes. The partial rescue of the defective F508del-CFTR function in CF-KM4 cells by L-isoDMDP is compared with miglustat and isoLAB in an approach to the treatment of cystic fibrosis.

  The Kiliani synthesis oil the 4 readily accessible ketohexoses (D-fructose, D-tagatose, L-sorbose, D-psicose) allows access to 4 diastereomeric 2-C-methyl-aldohexoses (2-C-methyl-D-mannose, 2-C-methyl-D-talose, 2-C-methyl-L-gulose, 2-C-methyl-D-allose) and 4 diastereomeric 2-C-methyl-alditols (2-C-methyl-mannitol, 2-C-methyl-D-talitol, 2-C-methyl-L-gulitol, 2-C-methyl-D-allitol). Microbial oxidation of 2-C-methyl-D-mannitol and 2-C-metllyl-L-gulitol gave 5-C-methyl-D-fructose; Microbial oxidation of 2-C-methyl-D-talitol afforded 5-C-methyl-D-psicose, whereas 2-C-methyl-D-allitol formed 5-C-methyl-Lpsicose. Both enantiomers of 5-C-methyl-fructose were equilibrated by D-tagatose-3-epimerase (DTE) with both enantiomers of 5-C-methyl-psicose. These transformations demonstrate that polyol dehydrogenases and DTE act on branched synthetic sugars. Full NMR analyses show that 5-C-methyl-D-fructose is present as the P-pyranose and P-furanose forms in a ratio of 90:10; all pyranose and furanose forms of 5-C-methyl-D-psicose are present in solution. The combination of chemical and biological procedures allows the environmentally friendly generation of a new family of branched monosaccharides. (C) 2008 Elsevier Ltd. All rights reserved.
