  Synthesis of 4-deoxy-4-fluoro analogues of 2-acetamido-2-deoxy-d-glucose and 2-acetamido-2-deoxy-d-galactose and their effects on cellular glycosaminoglycan biosynthesis

  摘要：

  4-Deoxy-4-fluoro analogues of 2-acetamido-2-deoxy-D-glucose and 2-acetamido-2-deoxy-D-galactose were synthesized and evaluated as inhibitors of hepatic glycosaminoglycan biosynthesis. 2-Acetamido-1,3,6-tri-O-acetyl-2,4-dideoxy-4-fluoro-D-glucopyranose (16) exhibited a reduction of [H-3]GlcN and [S-35]SO4 incorporation into hepatocyte cellular glycosaminoglycans to 12 and 18%, respectively, of the control cells, at 1.0 mM. Similarly, 2-acetamido-1,3,6-tri-O-acetyl-2,4-dideoxy-4-fluoro-D-gala (31) exhibited a reduction of [H-3]GlcN and [S-35]SO4 incorporation to 1 and 9%. respectively, of the control cells, at 1.0 mM. Unlike 16, 31 exhibited a reduction of [C-14]Leu incorporation into cellular protein to 57% of control cells, at 1.0 mM. (C) 2000 Elsevier Science Ltd. All rights reserved.

  A disaccharide implicated in anchoring of bacterial Surface-layer proteins to secondary cell wall glycopolymers has been prepared by glycosylation of a protected N-acetyl glucosamine acceptor with a glucopyranosyl donor to generate the β-(14)-linkage. Subsequent inversion of the configuration and azide introduction at position 2 with triflic anhydride, however, led to formation of a tetrazole derivative

• Synthesis and biological evaluation of a radiolabeled analog of methyl 2-acetamido-2,4-dideoxy-β-d-xylo-hexopyranoside directed towards influencing cellular glycosaminoglycan biosynthesis
  作者：Ali Berkin、Walter A Szarek、Robert Kisilevsky

  DOI：10.1016/s0008-6215(01)00285-3

  日期：2002.1

  Two methods are presented for the synthesis or methyl 2-acetamido-2,4-dideoxy-beta-D-xylo-hexopyranoside. The first method employs the Barton-McCombie deoxygenation methodology, and the second method utilizes an oxidation-beta-elimination methodology that allows for the incorporation of hydrogen isotopes into the title compound. Hence, methyl 2-acetamido-2,4-dideoxy-beta-D-xylo-hexopyranoside (4) and methyl 2-acetamido-2,4-dideoxy-beta-D-xylo-hexopyranoside-6-t (14) were synthesized and evaluated for their ability to inhibit hepatocyte, cell-surface glycosaminoglycan biosynthesis and to incorporate a [H-3] radiolabel into isolated glycosaminoglycans, respectively. Compound 4, at a concentration of 1.0 mM, demonstrated a reduction of D-[H-3]glucosamine and [S-35]sulfate incorporation into isolated glycosaminoglycans by 69 and 59%, of the control cultures, respectively. At 10 and 20 mM, 4 demonstrated a maximum inhibition of incorporation of both radiolabels to approximately 10% of the control cultures. Compound 14 demonstrated a maximum incorporation of a [H-3] radiolabel into isolated cell-surface glycosaminoglycans at 10 and 20 mM. The mechanism of inhibition of glycosaminoglycan biosynthesis is due, in part, to the incorporation of a 4-deoxy moiety into glycosaminoglycan chains resulting in premature chain termination.
