Abstract
Sialyl type-II sulfo-oligosaccharides are gaining much attention as bioactive ligands for Siglecs. In this study, we have achieved the first synthesis of sialyl type-II sulfo-oligosaccharides chemoenzymatically by utilizing the transglycosylation activity of keratanase II. The oxazoline derivative of α(2→3)-sialylated 6,6'-di-sulfo-LacNAc (3) was newly designed as the glycosyl donor for enzymatic transglycosylation. Keratanase II efficiently catalyzed the transglycosylation of 3 with two kinds of glycosyl acceptors, 6-sulfo-Lewis X and 6,6'-di-sulfo-LacNAc derivatives, providing sialyl sulfo-hexasaccharide (1) and sialyl sulfo-pentasaccharide (2) with 86 and 95% yields, respectively. The products 1 and 2 showed higher affinity to Siglec-8 with KD 70 and 25 μmol·L-1, respectively, compared to the known ligand of the α(2→3)-sialylated 6,6'-di-sulfo-Lewis X with KD 185 μmol·L-1. Thus, this study will advance not only the study of Siglec-8 biology but also the exploration of functions of sialyl sulfo-oligosaccharides having various microstructures.

Abstract
LewisX (LeX) is a branched trisaccharide Galβ1→4(Fucα1→3)GlcNAc that is expressed on many cell surface glycoproteins and plays critical roles in innate and adaptive immune responses. However, efficient synthesis of glycopeptides bearing LeX remains a major limitation for structure-function studies of the LeX determinant. Here we report a total synthesis of a LeX pentasaccharide 1 using a regioselective 1-benzenesulfinyl piperidine/triflic anhydride promoted [3 + 2] glycosylation. The presence of an Fmoc-threonine amino acid facilitates incorporation of the pentasaccharide in solid phase peptide synthesis, providing a route to diverse O-linked LeX glycopeptides. The described approach is broadly applicable to the synthesis of a variety of complex glycopeptides containing O-linked LeX or sialyl LewisX (sLeX).
