  Cystic fibrosis and diabetes: isoLAB and isoDAB, enantiomeric carbon-branched pyrrolidine iminosugars

  摘要：

  Acetonides are the only protecting groups used in the syntheses of isoDAB from D-ribose and of isoLAB from D-tagatose. isoDAB is a potent and highly specific competitive a-glucosidase inhibitor (for rice alpha-glucosidase, K(i) = 4 mu M for isoDAB compared to K(i) 14 mu M for DAB). isoDAB is not an whereas DAB is a potent inhibitor of glycogen phosphorylase. This is the first example of any potent inhibition of glycosidases by a carbon-branched iminosugar pyrrolidine. Although isoLAB shows no inhibition of any glycosidase, preliminary experiments suggest that isoLAB partially rescues the defective F508del-CFTR function and so may have a role in the study of cystic fibrosis.

  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.

  can be introduced efficiently without the need for any acid or base catalysis and which is not prone to acid or base catalysed migration is a significant advantage for many syntheses. Benzhydryl [diphenylmethyl] ethers of sugar lactones are formed in high yield under neutral conditions when the corresponding alcohol is heated with diphenyldiazomethane in an inert solvent such as acetonitrile or toluene;

  对于许多合成而言，可在不需要任何酸或碱催化的情况下有效地引入保护基且不易于被酸或碱催化的迁移的保护基是重要的优点。当相应的醇与二苯基重氮甲烷在惰性溶剂（如乙腈或甲苯）中加热时，在中性条件下，糖内酯的苄基[二苯基甲基]醚可以高收率形成；这样就可以在没有任何其他试剂的情况下轻松保护对碱敏感的和高度受阻的叔醇。

  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.
