    O-[Methyl (2-O-acetyl-3-O-benzyl-4-O-levulinyl-alpha, and beta-L-idopyranosid)uronate] trichloroacetimidate and the corresponding n-pentenyl glycosides are efficient L-iduronic acid glycosyl donors. Both have been used for the high-yielding synthesis of basic disaccharide blocks which are useful for the subsequent synthesis of complex oligosaccharides related to heparin/heparan sulfate, and dermatan

  • Synthesis and anti-thrombin activity of a hexasaccharide corresponding to the binding site of dermatan sulfate to heparin cofactor II
    作者:Pascal Bourhis、Françoise Machetto、Philippe Duchaussoy、J.-P Hérault、Jean-Maurice Mallet、J.-M Herbert、Maurice Petitou、Pierre Sinay

    日期:1997.11
    A new synthetic route is described toward the hexasaccharide representing the heparin cofactor II binding region of dermatan sulfate, The anti-thrombin activity of this synthetic hexasaccharide is reported here for the first time, This compound is about mio hundred times less active than dermatan sulfate itself for its ability to inhibit thrombin via heparin cofactor II.

  • Syntheses of the methyl glycosides of the repeating units of chondroitin 4- and 6-sulfate
    作者:Jean-Claude Jacquinet

    日期:1990.6
    3,4,6-Tri-O-acetyl-D-galactal was transformed into methyl 6-O-acetyl-2-azido-4-O-benzyl-2-deoxy-beta-D-galactopyranoside and its 4-O-acetyl-6-O-benzyl analogue, each of which was glycosylated with activated, O-acetylated derivatives of methyl D-glucopyranosyluronate. The resulting beta-(1----3)-linked disaccharide derivatives were each reductively N-acetylated, hydrogenolysed, O-sulfated, and saponified to afford the disodium salts of methyl 2-acetamido-2-deoxy-3-O-(beta-D-glucopyranosyluronic acid)-4-O-sulfo-beta-D-galactopyranoside and the 6-O-sulfo analogue. D-Galactal was also transformed into activated derivatives of 2-azido-3,6-di-O-benzyl-2-deoxy-D-galactopyranose and their 3,4-di-O-benzyl analogues with various substituents at O-4 and O-6. These glycosyl donors were condensed with 6-O-protected derivatives of methyl 2,3-di-O-benzyl-beta-D-glucopyranoside to give the beta-(1----4)-linked disaccharide derivatives, which were selectively deprotected, then oxidised at C-6 of the gluco unit, reductively N-acetylated, selectively deprotected, O-sulfated at C-4 or C-6 of the galacto unit, and hydrogenolysed to give the disodium salts of methyl 4-O-(2-acetamido-2-deoxy-4-O-sulfo-beta-D-galactopyranosyl)-beta-D- glucopyranosiduronic acid and the 6-O-sulfo analogue.
