Abstract
Background:
Disaccharide core 1 (Galβ1-3GalNAc) is a common O-glycan structure in
nature. Biochemical studies have confirmed that the formation of the core 1 structure is an important
initial step in O-glycan biosynthesis and it is of great importance for human body.
Objective:
Our study will provide meaningful and useful sights for O-glycan synthesis and their bioassay.
And all the synthetic glycosides would be used as intermediate building blocks in the scheme
developed for oligosaccharide construction.
Methods:
In this article, we firstly used chemical procedures to prepare core 1 and its derivative,
and a novel disaccharide was efficiently synthesized. The structures of the synthesized compounds
were elucidated and confirmed by 1H NMR, 13C NMR and MS. Then we employed three human gut
symbionts belonging to Bacteroidetes, a predominantphyla in the distal gut, as models to study the
bioactivity of core 1 and its derivative on human gut microbiota.
Results:
According to our results, both core 1 and derivative could support the growth of B. fragilis,
especially the core 1 derivative, while failed to support the growth of B. thetaiotaomicron and B.
ovatus.
Conclusion:
This suggested that the B. fragilis might have the specificity glycohydrolase to cut the
glycosidic bond for acquiring monosaccharide.

Abstract
In this study, we designed a novel amphiphilic poly-(p-N-vinylbenzyl-D-glucuronamide) (PV6Gna) modified at the 6-OH position of glucose for hepatocyte recognition to address the mechanism of the interaction between mouse primary hepatocytes and the PV6Gna. PV6Gna bound to lectins specific for glucose but not galactose as did other glucose-derivatized polymers. However, hepatocyte adhesion onto the PV6Gna surface was inhibited in the presence of galactose and its analogues but not in the presence of glucose and its analogues. We also showed that hepatocyte adhesion to the PV6Gna surface was inhibited dose dependently by asialofetuin (ASF). Interactions between soluble PV6Gna and hepatocytes were inhibited by GalNAc, ASF, and EGTA in flow cytometry analysis using fluorescein isothiocyanate-conjugated PV6Gna. Hepatocyte adhesion to the PV6Gna surface was inhibited more effectively by GalNAc than by methyl beta-D-galactose. In flow cytometry analysis and cell adhesion assay, ASF competed for the inhibition of interaction between PV6Gna and hepatocytes 0.5-4 x 10(5)-fold more effectively than did GalNAc. These results demonstrate involvement of asialoglycoprotein receptors (ASGPRs) in the interaction between PV6Gna and hepatocytes. Furthermore, to clarify the mechanism of the interaction between glycopolymers modified at the 6-OH position of glucose and the hepatocyte, we prepared a gel particle containing 6-O-methacryloyl-d-glucose (PMglc) synthesized by an enzymatic method. ASGPRs could be detected using Western blot analysis following precipitation with PMglc in hepatocyte cell lysate. The precipitation of ASGPRs was inhibited in the presence of galactose, ASF, PV6Gna, and EGTA. The precipitation was inhibited more effectively by GalNAc than by methyl beta-d-galactose. ASGPRs were rarely precipitated by PMglc in the cell lysate that had been treated with ASF-conjugated Sepharose. Taken together, we suggest that mouse primary hepatocytes adhere to the PV6Gna surface mediated by ASGPRs, which specifically interacted with the glycopolymers modified at the C-6 position of glucose.

Abstract
Both the Entamoeba histolytica lectin, a virulence factor for the causative agent of amebiasis, and the mammalian hepatic lectin bind to N-acetylgalactosamine (GalNAc) and galactose (Gal) nonreducing termini on oligosaccharides, with preference for GalNAc. Polyvalent GalNAc-derivatized neoglycoproteins have >1000-fold enhanced binding affinity for both lectins (Adler,P., Wood,S.J., Lee,Y.C., Lee,R.T., Petri,W.A.,Jr. and Schnaar,R.L.,1995, J. Biol. Chem ., 270, 5164-5171). Substructural specificity studies revealed that the 3-OH and 4-OH groups of GalNAc were required for binding to both lectins, whereas only the E.histolytica lectin required the 6-OH group. Whereas GalNAc binds with 4-fold lower affinity to the E.histolytica lectin than to the mammalian hepatic lectin, galactosamine and N-benzoyl galactosamine bind with higher affinity to the E. histolytica lectin. Therefore, a synthetic scheme for converting polyamine carriers to poly-N-acyl galactosamine derivatives (linked through the galactosamine primary amino group) was developed to test whether such ligands would bind the E.histolytica lectin with high specificity and high affinity. Contrary to expectations, polyvalent derivatives including GalN6lys5, GalN4desmosine, GalN4StarburstTMdendrimer, and GalN8StarburstTMdendrimer demonstrated highly enhanced binding to the mammalian hepatic lectin but little or no enhancement of binding to the E.histolytica lectin. We propose that the mammalian hepatic lectin binds with greatest affinity to GalNAc "miniclusters," which mimic branched termini of N-linked oligosaccharides, whereas the E.histolytica lectin binds most effectively to "maxiclusters," which may mimic more widely spaced GalNAc residues on intestinal mucins.

Abstract
A series of peptidylglycoside derivatives, including the tris(GalNAc-aminohexyl) glycoside of tyrosyl(glutamyl)-glutamate (1) which is known to have sub-nanomolar affinity for the asialoglycoprotein receptor (ASGPr), have been synthesized using the protected tetra-O-acetyl aminohexyl glycoside (9) of N-acetylgalactosamine. The N-succinyl derivative of 1 was also prepared, providing a derivative for bioconjugate formation via carboxyl activation of the glycopeptide. Use of the protected glycoside 9 affords synthetic intermediates with increased solubility in organic solvents that are easier to purify and use in subsequent synthetic manipulations in comparison with compounds containing unprotected glycosides. These synthetic procedures will be generally applicable to the preparation of related compounds to probe binding to the ASGPr and the use of these cluster glycosides as ligands for targeted delivery to the liver.

Abstract
Syntheses of galactose derivatives that are useful in probing the binding specificity of galactose-specific lectins are reported. These include allyl 3-deoxy- and 4-deoxy-beta-D-xylo-hexopyranoside and several disaccharide glycosides having Gal(1-->2) and Gal(1-->3) linkages. The beta-linked Gal disaccharide isomers were produced using 2,3,4,6-tetra-O-acetyl-alpha-D-galactopyranosyl bromide as glycosyl donor and the 4,6-O-benzylidene derivatives of allyl beta-D-galactopyranoside, alpha-D-glucopyranoside, alpha-D-mannopyranoside, and 2-acetamido-2-deoxy-alpha-D-galactopyranoside as acceptors. Only the Gal(1-->3)-linked disaccharide was obtained when the benzylidene derivatives of the mannopyranoside and 2-acetamido-2-deoxygalactopyranoside were used. Attempts at the preparation of Gal(alpha, 1-->2)Gal and Gal(alpha, 1-->3)Gal disaccharide glycosides were made using the same strategy, but employing the 1-trichloro-acetimidate or 1-N-methylacetimidate of 2,3,4,6-tetra-O-benzyl-D-galactopyranose as the glycosyl donor. The latter imidate produced a mixture of Gal(alpha, 1-->2)Gal and Gal(alpha, 1-->3)Gal derivatives as major products, but the former gave the Gal(beta, 1-->2)Gal isomer as the major product.
