  Xylopyranoside-based agonists of d-myo-inositol 1,4,5-trisphosphate receptors: synthesis and effect of stereochemistry on biological activity

  摘要：

  The synthesis of a series of tetrahydrofuranyl alpha- and beta -xylopyranoside trisphosphates, designed by excision of three motifs of adenophostin A is reported. The synthetic route features improved preparations of allyl alpha -D-xylopyranoside and its 2-O-benzyl ether, and gives access to four diastereoisomeric trisphosphates, which show a range of abilities to mobilise Ca2+ from the intracellular stores of hepatocytes. A comparison of the potencies of the four trisphosphates provides useful information relating to the effects of stereochemical variation on the recognition of carbohydrate-based trisphosphates by D-myo-inositol 1,4,5-trisphosphate receptors. 1-O-[(3 'S,4 'R)-3-hydroxytetrahydrofuran-4-yl] alpha -D-xylopyranoside 3,4,3 ' -trisphosphate (8) is the most active member of the series with a potency close to Ins(1,4,5)P-3; a beta -linked analogue, 1-O-[(3 'R,4 'S)-3-hydroxytetrahydrofuran-4-yl] beta -D-xylopranoside 3,4,3 ' -trisphosphate, is ca. 20-fold weaker than Ins(1,4,5)P-3, and the other compounds are much less active. While no compound attained a potency close to that of adenophostin A, we believe that 8 represents the minimal structure for potent Ca2+-releasing activity in this type of carbohydrate-based analogue.

• Diastereoselective Nitrenium Ion-Mediated Cyclofunctionalization: Total Synthesis of (+)-Castanospermine
  作者：Edward G. Bowen、Duncan J. Wardrop

  DOI：10.1021/ol102371x

  日期：2010.11.19

  The asymmetric total synthesis of the cc-glucosidase inhibitor (+)-castanospermine is reported. The central theme in our approach to this polyhydroxylated alkaloid is the simultaneous generation of the piperidine ring and the C-1/8a erythro stereodiad through the diastereoselective, oxamidation of an unsaturated O-alkyl hydroxamate. This process is believed to proceed sequentially via singlet acylnitrenium and aziridinium ion intermediates.
