  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.

  C-Branched Iminosugars: α-Glucosidase Inhibition by Enantiomers of isoDMDP, isoDGDP, and isoDAB–l-isoDMDP Compared to Miglitol and Miglustat

  摘要：

  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.
