A practical, useful glycosylation method employing only allyl glycoside building blocks has been developed. The donor’s glycosylation reactivity is turned on via isomerization of its anomeric allyl protecting group into the corresponding prop-1-enyl moiety. Subsequent chemoselective activation with NIS/TfOH achieves high yields in glycosidic bond construction at room temperature. The efficacy and efficiency of this approach in carbohydrate synthesis is demonstrated in the concise synthesis of the fully protected Shigella flexneri serotype Y O-antigen.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. Introducing a new discovery about 14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide, Application of 14215-68-0.

Bacterial non-specific acid phosphatases normally catalyze the dephosphorylation of a variety of substrates. As shown previously the enzymes from Shigella flexneri and Salmonella enterica are also able to catalyze the phosphorylation of inosine to inosine monophosphate and D-glucose to D-glucose 6-phosphate (D-G6P) using cheap pyrophosphate as the phosphate donor. After optimization high yields (95%) are achieved in the latter reaction and we show here that it is possible to use these enzymes in a preparative manner. This prompted us to investigate by using 31P NMR and HPLC also the phosphorylation of a broad range of carbohydrates and alcohols. Many cyclic carbohydrates are phosphorylated in a regioselective manner. Non-cyclic carbohydrates are phosphorylated as well. Phosphorylation of linear alcohols, cyclic and aromatic alcohols is also possible. In all cases the acid phosphatase from Shigella prefers a primary alcohol function above a secondary one. We conclude that these enzymes are an attractive alternative to existing chemical and enzymatic methods in the phosphorylation of a broad range of compounds.

It has been recognized that human hair lipids play crucial roles in the integrity of cells and matrices, while the details of distribution and structure of the minor lipids are hardly known. Here we investigated the lipids at the hair surface, at the interface between cuticle and cortex and in the interior of hair (cortex, medulla and melanin granules). Hair lipids and fatty acids and their metabolites were detected and characterized by using infrared spectroscopy and several mass spectrometry techniques (FTIR, ToF-SIMS, GCMS, and ESI-MS). As a result, it was found that unsaturated fatty acids were present more in the cortex of hair than at the hair surface. At the interface between cuticle and cortex, it is suggested that steryl glycoside-like lipids containing N-acetylglucosamine were present, and contributing to the adhesion between the cuticle and cortex of hair. Oxidative metabolites derived from integral fatty acids such as linoleic and alpha-linolenic acids were found in the hair bulb and melanin granules. Especially the oxidative metabolites of alpha-linolenic acid were integrated into the lipids non-covalently and tightly bound to melanin granules (namely, melanin lipids) and suggested as being involved in the biosynthetic processes of melanosome.

Glycosynthases are promising enzyme catalysts for glycoside synthesis. Derived from glycoside hydrolases by mechanistic repurposing of their active site, glycosynthases utilize suitably activated glycosyl donors for glycosylation, yet they are unable to hydrolyze the products thus formed. Although primed for synthetic application by their design, glycosynthases have yet to see actual use in carbohydrate production. To challenge limitations on glycosynthase applicability perceived from the process chemistry point of view, here we developed a glycosynthase (D746E variant) from Bifidobacterium bifidum beta-N-acetylhexosaminidase that is highly active synthetically (?100 mumol min-1 mg-1) and fully chemo- and regioselective when using N-acetyl-d-glucosamine 1,2-oxazoline for beta-1,3-glycosylation of lactose. We thus established a chemoenzymatic process technology for production of lacto-N-triose II, a core structural unit of human milk oligosaccharides. Using equivalent amounts of oxazoline (prepared chemically in 40% yield from N-acetyl-d-glucosamine) and lactose, we obtained lacto-N-triose II (515 mM; 281 mg mL-1 90% yield; ?1 h reaction time) immediately recoverable from the reaction in 85% purity. These metrics of process efficiency reveal the prodigious potential of the glycosynthase for trisaccharide production.

The influence from the chitosan molecular weight on its interaction with cell membrane models has been studied. A low molecular weight chitosan (LMWChi) adsorbed from the subphase expanded the surface pressure-area and surface potential-area isotherms of dimyristoyl phosphatidic acid (DMPA) monolayers and decreased the compressional modulus. The expansion in the monolayers and the decrease in the compressional modulus were larger for LMWChi than for a high molecular weight chitosan (Chi). The polymeric nature is still essential for the interaction though, which was demonstrated by measuring negligible changes in the mechanical properties of the DMPA monolayer when the subphase contained glucosamine and acetyl-glucosamine. The results were rationalized in a model through which chitosan interacted with the membrane via electrostatic and hydrophobic interactions, with the smaller chains of LMWChi having less steric hindrance to be accommodated in the membrane. In summary, the activity based on membrane interactions depends on the distribution of molar mass, with lower molecular weight chitosan more likely to have stronger effects.

A chitin-binding hemagglutinin was purified about 50-fold from the culture filtrate of Conidiobolus lamprauges.Hemolytic factor(s) and beta-N-acetylglucosaminidase coexisting with the hemagglutinin were removed by treating the culture filtrate with CM Sephadex and formalinized human erythrocytes.Purified hemagglutinin formed large aggregates upon ultrafiltration.The hemagglutinin had a major and a minor band in sodium dodecyl sulfate polyacrylamide gel electrophoresis.The major band of this hemagglutinin was a protein containing a small amount of sugar, and its molecular weight was approximately 86,000.The hemagglutinin was strongly inhibited by N-acetyl chitobi, tri and tetraose; moderately inhibited by phenyl and p-nitrophenyl beta-N-acetyl-D-glucosaminides; and weakly inhibited by D-glucosamine and N-acetyl-D-glucosamine. beta-Configuration was required for inhibition.
