摘要

Fucosylated chondroitin sulfate (FuCS) is a structurally distinct glycosaminoglycan with excellent anticoagulant activity. Studies show that FuCS and its depolymerized fragments exhibit a different anticoagulant mechanism from that of heparin derivatives, with decreased risks of adverse effects and bleeding. However, further exploitation has been hindered by the scarcity of structurally defined oligosaccharides. Herein, facile method is reported for the synthesis of the repeating trisaccharide unit of FuCS based on the degradation of chondroitin sulfate polymers. A series of simplified FuCS glycomimetics that have highly tunable structures, controllable branches, and defined sulfation motifs were generated by copper-catalyzed alkyne-azide cycloaddition. Remarkable improvement in activated partial thromboplastin time (APTT) assay activities was observed as the branches increased, but no significant influences were observed for prothrombin time (PT) and thrombin time (TT) assay activities. Further FXase inhibition tests suggested that glycoclusters 33b-40b selectively inhibited intrinsic anticoagulant activities, but had little effect on the extrinsic and common coagulation pathways. Notably, glycoclusters with the 2,4-di-O-sulfated fucosyl residue displayed the most potency, which was in consistent with that of natural polysaccharides. These FuCS clusters demonstrated potency to mimic linear glycosaminoglycans and offer a new framework for the development of novel anticoagulant agents.
