  Synthesis of linear-type chondroitin clusters having a C8 spacer between disaccharide moieties and enzymatic transfer of d-glucuronic acid to the artificial glycans

  摘要：

  Newly designed linear-type glycoclusters were synthesized which involve a chondroitin repeating disaccharide ligand and a hydrophobic octyl ether spacer. The spacer mimics the corresponding disaccharide unit. Repeating elongation of the pseudo-tetrasaccharide that was derived from the common cluster unit [--> 8)-octyl-(1 --> 3)-beta -D-Gal-NAc-(1 --> 4)-beta -D-GlcA-(1 -->] allowed the syntheses of up to the pseudo-decasaccharide analog of chondroitin. An enzymatic D-GlcA transfer at the non-reducing end of the synthesized artificial glycans by GlcATase II was observed. (C) 2001 Published by Elsevier Science Ltd.
