AbstractFucosylated glycosaminoglycan (FG), a glycosaminoglycan derivative containing distinct sulfated fucose (FucS) branches, displays potent anticoagulant activity by inhibiting the intrinsic tenase complex (iXase). Herein, AmFG, SvFG and HaFG from three species of sea cucumbers were isolated and depolymerized by beta-eliminative cleavage. Three series of fragments, A1-A4, S1-S4 and H1-H4, were purified from the depolymerized FGs. Based on structural analysis of these fragments, three FGs were deduced as -{-> 4)-[L-FucS-alpha(1 -> 3)]-D-GlcA-beta(1 -> 3)-D-GalNAc(4S6S)-beta(1}(n-). The structures differed in sulfation types of FucS, namely, most of FucS in AmFG was Fuc(3S4S), but the FucS in SvFG was Fuc(2S4S), while the FucS in HaFG was Fuc(3S4S), Fuc(2S4S) and Fuc(4S). However, all FucS branches attached to C-3 of GlcA as monosaccharides. Anticoagulant and anti-iXase assays showed the octasaccharide is the minimum fragment for potent anticoagulant activity via anti-iXase irrespective of FucS types. Among FG fragments with same degree of polymerization, oligosaccharides containing Fuc(2S4S) had more potent anti-iXase activity.
