An efficient, convenient protocol for the preparation of per-O-acetylated p-tolylthio glycosides is described. Treatment of various unprotected sugars, including 2-deoxy-2-amino sugars, sialic acid, lactose, and maltose, with acetic anhydride using SnCl4 as a catalyst, and subsequently with p-tolylthiol, furnished the corresponding thioglycosides in 71%-90% yield under solvent-free conditions.

The carbohydrate-binding properties of Castanea crenata agglutinin (CCA) were investigated by an enzyme-linked lectin absorbent assay. The binding ability of each carbohydrate was compared using IC50 values. CCA exhibited mannose/glucose specificity, as observed with many mannose-binding jacalin-related lectins. For oligosaccharides containing glucose, it has been shown that the degree of polymerization and the linkage mode of glucose residues have no effect on CCA-carbohydrate interaction; thus, only the non-reducing end glucose unit in glucooligosaccharides may be involved in the interaction with CCA. Among mannooligosaccharides, CCA strongly recognized alpha-(1?3)-d- Man-[alpha-d-Man-(1?6)]-d-Man, which is a core in N-linked carbohydrate chains. By considering the results with glycoproteins, it is likely that CCA binds preferentially to mono- or non-sialylated biantennary carbohydrate chains. We also obtained Kd values by analysis of the dependency of the IC50 on CCA concentration, based on the hypothesis that CCA has a single binding site or two equivalent binding sites. The estimated Kd values for mannose, glucose and alpha-(1?3)-d-Man-[alpha-d-Man- (1?6)]-d-Man were 2.39, 7.19 and 0.483 mM, respectively. The relative binding abilities showed good agreement with the relative inhibition intensities. Isothermal calorimetric titration was carried out to directly estimate the dissociation constants of CCA for mannose and for alpha-d-Man-(1?3)-d-Man. The values were 2.34 mM for mannose and 0.507 mM alpha-d-Man-(1?3)-d-Man. These results suggest that the relative inhibition intensity represents the ratio of Kd values and that CCA has a single or two equivalent binding sites.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 14215-68-0 is helpful to your research., Reference of 14215-68-0

Clanis bilineata larvae are widely consumed in China. In this study, chitooligosaccharides were prepared from C. bilineata larvae skin by demineralisation, deproteination, washing, drying, deacetylation, hydrolysis using commercial alpha-amylase, filtration, setting the preparation at approximately 15% (w/v), precipitation with 6 volumes of ethanol, and drying at 60 C for 2 h. The optimal hydrolysis conditions were determined as follows: pH 5.5; temperature, 55 C; enzyme amount, 40. mg/(g chitosan); reaction time, 4 h. The Fourier transform infrared spectra revealed that chitooligosaccharides with a degree of polymerisation in the range of 2-8 were the main component of the resulting product, with the chitooligosaccharide content and yield being 95.8% and 96.2% (w/w), respectively. The resulting product showed high antibacterial activity compared with the original chitosan.

Neoglycosylations are increasingly being employed in the synthesis of natural products, drug candidates, glycopeptide mimics, oligosaccharide analogues, and other applications, but the efficiency of these reactions is usually limited by slow reaction times. Here, we show that aniline derivatives such as 2-amino-5-methoxybenzoic acid enhance the rate of acid-catalyzed neoglycosylation for a range of sugar substrates up to a factor of 32 relative to the uncatalyzed reaction.

The trifluoroacetic acid adduct of tetranuclear zinc cluster Zn4(OCOCF3)6O catalysis in per-O-acetylation and de-O-acetylation of carbohydrates at 70 C can be tuned by adjusting the reaction medium. Per-O-acetylation of hexopyranoses with a near stoichiometric amount of acetic anhydride in toluene resulted in the exclusive formation of pyranosyl products as an anomeric mixture, whereas de-O-acetylation of acetates occurred in methanol in high yields. In the latter, methanol acts as both nucleophile and solvent, and the reaction conditions were compatible to acid- and base-sensitive groups and amino acid derivatives.
