  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.

  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.
