  Synthesis and biological evaluation of deoxy salacinols, the role of polar substituents in the side chain on the α-glucosidase inhibitory activity

  摘要：

  Three analogs (5, 6, and 7) lacking polar substituents in the side chain of a naturally occurring a-glucosidase inhibitor, salacinol (la), were synthesized by the coupling reaction of a thiosugar, 1,4-dideoxy-1,4-epithio-D-arabinitol (3), with cyclic sulfates (8, 9, and 10), and their a-glucosidase inhibitory activities were examined. All these simpler analogs (5, 6, and 7) showed less inhibitory activity compared to la, and proved the importance of cooperative role of the polar substituents for the a-glucosidase inhibitory activity. A practical synthetic route to 3 starting from D-xylose is also described. (c) 2005 Elsevier Ltd. All rights reserved.
