Graphical Abstract

To the nines: Structurally defined fucosylated chondroitin sulfate hexa- and nonasaccharides were synthesized in 12 linear steps from chondroitin sulfate through the enzymatic degradation of chondroitin (see scheme). The nonasaccharide displayed selective intrinsic factor Xase complex inhibitory activity by binding to factor IXa with high affinity, thus showing promise for the development of anticoagulant agents targeting the intrinsic coagulation pathway.

Abstract

Fucosylated chondroitin sulfate (FuCS) is a structurally distinct glycosaminoglycan, and its oligosaccharides exhibit excellent anticoagulant activity with lower risks of adverse effects and bleeding. Herein we report a facile approach to the synthesis of FuCS hexa- and nonasaccharides on the basis of the enzymatic degradation of chondroitin over 12 linear steps. As compared with a clinical low-molecular-weight heparin drug (enoxaparin), the nonasaccharide synthesized in this study displayed similar APTT activity and selective intrinsic factor Xase complex inhibitory activity ((12.9±0.83) nm) by binding to factor IXa with high affinity, thus offering promise for the development of new anticoagulant agents targeting the intrinsic coagulation pathway.
