Abstract
The first synthetic carbohydrate based potential anti-Salmonella Enteritidis vaccine has been developed by conjugating a synthetic tetrasaccharide antigen with bacteriophage Qβ. High levels of specific and long lasting anti-glycan IgG antibodies were induced by the conjugate, which completely protected mice from lethal bacterial challenges in a passive transfer model.

Abstract
Abstract
The recombinant catalytic α-subunit of N-glycan processing glucosidase II from Schizosaccharomyces pombe (SpGIIα) was produced in Escherichia coli. The recombinant SpGIIα exhibited quite low stability, with a reduction in activity to <40% after 2-days preservation at 4 °C, but the presence of 10% (v/v) glycerol prevented this loss of activity. SpGIIα, a member of the glycoside hydrolase family 31 (GH31), displayed the typical substrate specificity of GH31 α-glucosidases. The enzyme hydrolyzed not only α-(1→3)- but also α-(1→2)-, α-(1→4)-, and α-(1→6)-glucosidic linkages, and p-nitrophenyl α-glucoside. SpGIIα displayed most catalytic properties of glucosidase II. Hydrolytic activity of the terminal α-glucosidic residue of Glc2Man3-Dansyl was faster than that of Glc1Man3-Dansyl. This catalytic α-subunit also removed terminal glucose residues from native N-glycans (Glc2Man9GlcNAc2 and Glc1Man9GlcNAc2) although the activity was low.

Abstract
The development of glycobiology relies on the sources of particular oligosaccharides in their purest forms. As the isolation of the oligosaccharide structures from natural sources is not a reliable option for providing samples with homogeneity, chemical means become pertinent. The growing demand for diverse oligosaccharide structures has prompted the advancement of chemical strategies to stitch sugar molecules with precise stereo- and regioselectivity through the formation of glycosidic bonds. This Review will focus on the key developments towards chemical O-glycosylations in the current century. Synthesis of novel glycosyl donors and acceptors and their unique activation for successful glycosylation are discussed. This Review concludes with a summary of recent developments and comments on future prospects.

Abstract
![]()
Melioidosis is an emerging infectious
disease caused by Burkholderia pseudomallei and is associated with
high morbidity and mortality rates in endemic areas. Antibiotic treatment
is protracted and not always successful; even with appropriate therapy,
up to 40% of individuals presenting with melioidosis in Thailand succumb
to infection. In these circumstances, an effective vaccine has the
potential to have a dramatic impact on both the scale and the severity
of disease. Currently, no vaccines are licensed for human use. A leading
vaccine candidate is the capsular polysaccharide consisting of a homopolymer
of unbranched 1→3 linked 2-O-acetyl-6-deoxy-β-d-manno-heptopyranose. Here, we present the
chemical synthesis of this challenging antigen using a novel modular
disaccharide assembly approach. The resulting hexasaccharide was coupled
to the nontoxic Hc domain of tetanus toxin as a carrier
protein to promote recruitment of T-cell help and provide a scaffold
for antigen display. Mice immunized with the glycoconjugate developed
IgM and IgG responses capable of recognizing native capsule, and were
protected against infection with over 120 × LD50 of B. pseudomallei strain K96243. This is the first
report of the chemical synthesis of an immunologically relevant and
protective hexasaccharide fragment of the capsular polysaccharide
of B. pseudomallei and serves as the
rational starting point for the development of an effective licensed
vaccine for this emerging infectious disease.

Abstract
Chemo-enzymatic strategies hold great potential for the development of stereo- and regioselective syntheses of structurally defined bioactive oligosaccharides. Herein, we illustrate the potential of the appropriate combination of a planned chemo-enzymatic pathway and an engineered biocatalyst for the multistep synthesis of an important decasaccharide for vaccine development. We report the stepwise investigation, which led to an efficient chemical conversion of allyl α-d-glucopyranosyl-(1→4)-α-l-rhamnopyranosyl-(1→3)-2-deoxy-2-trichloroacetamido-β-d-glucopyranoside, the product of site-specific enzymatic α-d-glucosylation of a lightly protected non-natural disaccharide acceptor, into a pentasaccharide building block suitable for chain elongation at both ends. Successful differentiation between hydroxyl groups features the selective acylation of primary alcohols and acetalation of a cis-vicinal diol, followed by a controlled per-O-benzylation step. Moreover, we describe the successful use of the pentasaccharide intermediate in the [5 + 5] synthesis of an aminoethyl aglycon-equipped decasaccharide, corresponding to a dimer of the basic repeating unit from the O-specific polysaccharide of Shigella flexneri 2a, a major cause of bacillary dysentery. Four analogues of the disaccharide acceptor were synthesized and evaluated to reach a larger repertoire of O-glucosylation patterns encountered among S. flexneri type-specific polysaccharides. New insights on the potential and limitations of planned chemo-enzymatic pathways in oligosaccharide synthesis are provided.

Abstract
Abstract
Endo-α-mannosidase, a GH99-family glycoside hydrolase, cleaves α-mannoside linkages with glucose residues. This enzyme is proposed to play a critical role in N-glycan processing for deglucosylation. To measure endo-α-mannosidase activity, we synthesized a fluorescently labeled tetrasaccharide derivative (Glcα1-3Manα1-2Manα1-2Manα1-O–C3H6–NH-Dansyl) in a stereocontrolled manner. The tetrasaccharide skeleton was prepared by step-wise coupling using mannose donors 4 and 7. The 1,2-cis α-glycosidic linkage on the non-reducing end of the glucose residue was constructed by inversion of the stereochemistry of the C-2 hydroxyl group in the α-mannose residue. Finally, the dansyl group was introduced at the reducing end via an aminopropyl linker. This probe successfully measured endo-α-mannosidase activity.
