Datura stramonium seeds contain at least three chitin-binding isolectins [termed Datura stramonium agglutinin (DSA)] as homo- or heterodimers of A and B subunits. We isolated a cDNA encoding isolectin B (DSA-B) from an immature fruit cDNA library; this contained an open reading frame encoding 279 deduced amino acids, which was confirmed by partial sequencing of the native DSA-B peptide. The sequence consisted of: (i) a cysteine (Cys)-rich carbohydrate-binding domain composed of four conserved chitin-binding domains and (ii) an extensin-like domain of 37 residues containing four SerPro4-6 motifs that was inserted between the second and third chitin-binding domains (CBDs). Although each chitin-binding domain contained eight conserved Cys residues, only the second chitin-binding domain contained an extra Cys residue, which may participate in dimerization through inter-disulfide bridge formation. Using matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry, the molecular mass of homodimeric lectin composed of two B-subunits was determined as 68,821 Da. The molecular mass of the S-pyridilethylated B-subunit were found to be 37,748 Da and that of the de-glycosylated form was 26,491 Da, which correlated with the molecular weight estimated from the deduced sequence. Transgenic Arabidopsis plants overexpressing the dsa-b demonstrated hemagglutinating activity. Recombinant DSA-B was produced as a homodimeric glycoprotein with a similar molecular mass to that of the native form. Moreover, the N-terminus of the purified recombinant DSA-B protein was identical to that of the native DSA-B, confirming that the cloned cDNA encoded DSA-B.

Several oxidative reactions can be effected with MnO2 in the presence of substoichiometric quantities of DDQ. These transformations include oxidative cyclization, deprotection, and dehydrogenation reactions. The use of MnO2 as a terminal oxidant for DDQ-mediated reactions is attractive based on economical and environmental factors.

beta-N-Acetylhexosaminidases feature so-called wobbling specificity, which means that they cleave substrates both in gluco-and galacto-configurations, with the activity ratio depending on the enzyme source. Here we present the new finding that fungal beta-N-acetylhexosaminidases are able to hydrolyze and transfer 4-deoxy-N-acetylhexosaminides with high yields. This clearly demonstrates that the 4-hydroxy moiety at the substrate pyranose ring is not essential for substrate binding to the enzyme active site, which was also confirmed by molecular docking of the tested compounds into the model of the active site of beta-Nacetylhexosaminidase from Aspergillus oryzae. A set of four 4-deoxy-N-acetylhexosaminides was synthesized and screened against a panel of beta-N-acetylhexosaminidases (extracellular and intracellular) from various sources (fungal, human, animal, plant and bacterial) for hydrolysis. The results of this screening are reported here, as well as the structures of three novel 4?-deoxy-disaccharides prepared by transglycosylation reaction with high yields (52% total disaccharide fraction) using beta-N-acetylhexosaminidase from Talaromyces flavus.

Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 101691-65-0, Name is (Tetrahydro-2H-pyran-4-yl)methyl 4-methylbenzenesulfonate, molecular formula is C13H18O4S.

Process research and development for a synthesis of the chiral carboxylic acid (R)-2 as a key intermediate of the glucokinase activator (R)-1 is described. The construction of the stereocenter at the alpha-carbon is a key point for the synthesis of (R)-2. The proposed process utilizes desymmetrization of a ketene in situ generated from the corresponding racemic carboxylic acid Rac-2 with (R)-pantolactone as a chiral auxiliary followed by hydrolysis of the resulting ester. This key step has been successfully scaled up to 20 kg, which demonstrates that this synthetic approach is comparable with a previously reported approach via enantioselective hydrogenation.

Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps. 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.

The syntheses of 4-nitrophenyl beta-glycosides of the 3-thio and 4-thio analogues of the two principal 2-acetamido-2-deoxy-hexoses found in living systems, GlcNAc and GalNAc, are described. While synthesis of the 4-thio analogues could be achieved via nucleophilic displacements of sulfonate derivatives with thioacetate, problems with neighbouring group acetamido participation necessitated the use of sulfamidate intermediates for the 3-thio analogues. These 3- and 4-thio analogues are employed in the chemo-enzymatic synthesis of thio-oligosaccharide analogues of structures present in glycosaminoglycans, glycoproteins and glycolipids.

3,6-Anhydro sugars are common structures in algal polysaccharides and occur in the furanodictine and sauropunol natural products. We have found that treatment of 6-O-tosylpyranosides with tetrabutylammonium fluoride provides a mild, high-yielding synthesis of 3,6-anhydro sugars. Using O-glycoside substrates, 3,6-anhydropyranosides are isolated and the use of N,O-dimethyl hydroxylamine glycosides yields 3,6-anhydrofuranosides. Applying this approach, concise synthetic routes to several 3,6-anhydro sugar natural products are reported, including furanodictine A and sauropunols A-D.

A new, selective, and sensitive ion-pair RP-HPLC method for the simultaneous determination of three classes of natural organic compounds, i.e., carbohydrates, amino sugars, and uronic acids, in environmental samples is presented, p-Aminobenzoic acid is used for precolumn derivatization of the analytes, enabling fluorescence (lambdaex 313 nm, lambdaem 358 nm) or photometric detection (303 nm). The dependence of the derivatization yield on the reaction conditions is examined. Derivatives of lactose, galactose, glucose, mannose, xylose, arabinose, galacturonic acid, glucuronic acid, N-acetylglucosamine, and glycerinealdehyde were separated on a RP-C18 column with hydrophilic end capping within 35 min, applying TBAHSO4 as the ion-pair reagent. The concentration detection limits range between 20 and 30 mug L-1 ((1-2) × 10-7 M) for fluorescence detection and between 30 and 75 mug L-1 for UV detection. A good linearity is achieved in the concentration range from 50 mug L-1 to 100 mg L-1 (r2 >0.99).
