Synthesis of 3,6-dideoxy-4-C-(41-hydroxyethyl)hexopyranoses (yersinioses) from 1,6-anhydro-β-d-glucopyranose
摘要:
A series of isomers of 3,6-dideoxy-4-C-(4(1)-hydroxyethyl)-D-hexopyranose (yersiniose), structural components of the O-specific polysaccharides from the Yersinia genus, have been synthesised from 1,6-anhydro-beta-D-glucopyranose (levoglucosan).
A key disaccharide unit in heparin, O-(2-deoxy-2-sulfamido-6-O-sulfo-alpha-D-glucopyranosyl)-(1-->4)-2-O-sulfo-alpha-L-idopyranosyluronic acid, was previously found to be responsible for the binding interaction of heparin to platelets. A clustering effect to enhance the binding was found to be dependent on the number and frequency of the disaccharide units in a heparin molecule. To systematically examine the clustering effect, three oligomer-model compounds containing two or three units of the disaccharide were synthesized. These compounds inhibited (3)H-Iabelled heparin binding to human platelets more strongly than a compound containing only one unit of the disaccharide, (C) 1999 Elsevier Science Ltd.
