Chemical synthesis of glycoproteins through three different strategies, from the same reagent, is herein described. The flexibility of this system, which allows the comparison of different linkage motifs between the same glycan and protein, is shown by one-step diversification of a GlcNAc-ylating reagent and its application in both site-specific and non-site-specific glycoprotein synthesis to create different conjugates from common representative protein scaffolds.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide, molecular formula is C8H15NO6.

Immunoenzymatic assays using gold plates and quartz crystal microbalance (QCM) analysis were carried out in order to evaluate chitosan/IgG interaction. Two chitosan solutions (S1 and S2) were prepared with different concentrations of NaOH (0.8%-S1 and 8%-S2). Absorbances 3-fold higher were obtained when chitosan (S2) was used as support when compared with direct IgG adsorption on gold. S1 on gold showed a better stability (at 22 C, for 72 h) for IgG immobilization when compared with S2. However, S1 was used on QCM analysis and the IgG adsorption led to a non-Sauerbrey response, in which the mass on the electrode surface promote a proportional increase in the crystal resonant frequency. Direct IgG adsorption on gold electrode led to a 14.19% (¡À2.43) increase in crystal frequency. When S1 was used as a support for IgG, a better immobilization occurred, causing a 24.34% (¡À0.75) variation in crystal frequency. The structure of chitosan was shown to be efficient for IgG immobilization both in the immunoenzymatic method and in the QCM system.

(Chemical Presented) Strengthening the bond: The introduction of a thiol tag in combination with chemoselective ligation to form a disulfide-linked bioconjugate is a selective and useful method for site-selective protein glycosylation. The phosphine-mediated desulfurization of such glycoconjugates to their reductant-resistant thioether-linked counterparts completes a convergent, site-selective synthesis of thioether-linked glycoproteins (see scheme).

Various 2-pyridyl 1-thioglycosides, important synthetic intermediates and enzyme inhibitors in sugar chemistry, have been synthesized directly from the corresponding unprotected sugars in good yields by using 2-chloro-1,3- dimethylimidazolinium chloride (DMC) as dehydrative condensing agent. The reaction proceeds in aqueous media without using any protecting groups, affording 2-pyridyl 1-thioglycosides with beta-configuration selectively. According to the present method, not only unprotected monosaccharides but also unprotected oligosaccharides, such as cello-oligosaccharides, chito-oligo-saccharides, malto-oligosaccharides, and glucosamine oligomers, can be converted to the corresponding 2-pyridylthio derivatives, which would greatly expand the utility of aryl 1-thioglycosides in sugar chemistry.

The corresponding 4-substituted glycosyl thiosemicarbazide derivatives (6a-6l) were obtained by the reaction of glycosyl isothiocyanate 4 with various hydrazides. Further cyclization with the system of p-TsCl/TEA led to the formation of N-glycosyl-5-substituted 1,3,4-thiadiazole-2-amine (7a-7l). Subsequent removal of the acetyl groups were conducted using the system of NaOMe/MeOH. The chemical structures of all new products were confirmed by IR, 1H NMR and ESI-HRMS. The acetylcholinesterase (AChE) inhibitory activities of those compounds were tested by Ellman’s method. Among them, the compound 8h possessed the best acetylcholinesterase-inhibition activity with IC50 of 18.38 ¡À 0.89 muM.

Here, N-acetyl-D-glucosamine (GlcNAc), the monomer composing the second most abundant biopolymer, chitin, was efficiently converted into 5-hydroxymethylfurfural (5-HMF) using ionic liquid (IL) catalysts in a water/dimethyl sulfoxide (DMSO) mixture solvent. Various reaction parameters, including reaction temperature and time, DMSO/water mass ratios and catalyst dosage were optimized. A series of ILs with different structures were analyzed to explore their impact on GlcNAc conversion. The substrate scope was expanded from GlcNAc to D-glucosamine, chitin, chitosan and monosaccharides, although 5-HMF yields obtained from polymers and other monosaccharides were generally lower than those from GlcNAc. Moreover, the IL N-methylimidazolium hydrogen sulfate ([Hmim][HSO4]) exhibited the best catalyst performance (64.6% yield) when GlcNAc was dehydrated in a DMSO/water mixture at 180?C for 6?h without the addition of extra catalysts. To summarize, these results could provide knowledge essential to the production of valuable chemicals that are derived from renewable marine resources and benefit biofuel-related applications.

Pyridylamination is a versatile method for fluorescence labeling of oligosaccharides. The technique affords sensitive detection of saccharides with reducing termini and high-resolution separation by high-performance liquid chromatography. The conventional method, based on a liquid-phase reaction, has been extensively used in various aspects of glycobiology and glycotechnology. Unfortunately, the necessity for removing excess 2-aminopyridine makes the technique both laborious and time-consuming. Furthermore, removal of excess reagent can result in a significant loss of short saccharide components. In the present paper, we report an alternative methodology based on a “gas-phase” reaction, in which dried saccharides are reacted with vaporized 2-aminopyridine. The resultant Schiff base was also reduced in the gas phase within the same reaction microtube using a purpose-built device. The newly developed procedure was applied to both monosaccharide (GlcNAc) and oligosaccharides (isomalto-oligosaccharides) at quantitative yields with no requirement to remove excess reagent. The acid-labile sialyl linkages of alpha2-6-disialobiantennary oligosaccharides proved to be fully stable during the procedure. The developed method was also successfully applied to profiling N-linked oligosaccharides liberated from glycoproteins by hydrazinolysis and, thus, should contribute to various fields of glycomics.

Human lactoferrin (LF) specifically binds to human monocytic leukemia cell line THP-1 cells differentiated into macrophages, and it has been suggested that the poly-N-acetyllactosaminyl saccharide chains of LF are involved. We partially purified and characterized LF-binding proteins with affinity for polylactosamines from THP-1 cells. LF-binding activity was solubilized by nonionic detergent Triton X-100 from THP-1 cell membrane, and subjected to affinity chromatography using an LF-Sepharose column. LF- binding activity, detected by ligand blotting assay, was elated and further fractionated by affinity chromatography using a Sepharose column coupled with band 3, a polylactosaminyl chain-containing glycoprotein of human erythrocyte membrane. LF-binding activity was separated into three fractions (frs. B1, B2, and B3). These fractions exhibited hand 3-binding activity as detected by ligand blotting assay. Dodecylsulfate-polyacrylamide get electrophoresis of frs. B1, B2, and B3, followed by detection of LF-binding activity on Western blots, indicated that frs. B1, B2, end B3 contained LF-binding proteins with a molecular mass of 35, 50 and 80, and 35 – 37 kDa, respectively. Binding of LF to each of the fractions on the dot blots was partially inhibited by LF oligosaccharides, band 3 oligosaccharides and lacto-N-neotetraose, each containing di-N-acetyllactosaminyl or analogous structure, Galbeta ? 4GlcNAcbeta1 ? 3Galbeta1 ? 4GlcNAc (or Glc). These results suggest that the 35, 50 and/or 80, and 35 – 37 kDa proteins on THP-1 cells are LF-binding proteins with poly-lactosamine-binding ability.
