Academic researchers, R&D teams, teachers, students, policy makers and the media all rely on us to share knowledge that is reliable, accurate and cutting-edge. 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, 14215-68-0.

In an effort to develop transition-state mimetics of the glycosidase-catalyzed reaction, five- and six-membered azasugars and their homo-analogs were prepared and tested as inhibitors of glycosidases. Inhibition studies indicate that the fucosyl cationlike, five-membered imine 1 and its reduced form 2 are potent inhibitors of alpha-fucosidase from bovine kidney with respective K(i) values of 160 nM and 2 muM. The five-membered homoaminoazasugar 3 is also a potent inhibitor of the enzyme (K(i) = 1.9 x 10-6M), while the glucose and mannose-like six-membered homoaminoazasugars 4 and 5 are less potent than the corresponding 1-deoxyazasugars as inhibitors of alpha-glucosidase and alpha-mannosidase, respectively. The primary amino group was placed in an attempt to introduce additional electrostatic interactions in the active site. The inhibitory activities are, however, in the high muM range. Synthesis of homoazasugars structurally related to a disaccharide and a nucleoside is also described.

A novel type of artificial glycoprotein was developed, by using dihydrofolate reductase (DHFR) and methotrexate (MTX) as a protein-ligand pair. Various oligosaccharides linked to MTX were shown to bind tightly with DHFR and afforded oligosaccharide-grafted protein, which could be isolated easily by lectin beads.

Pronase a mixture of proteases from Streptomyces griseus has been found to be a good catalyst for transacylation in organic solvents.With equimolar concentrations of p-nitrophenyl acetate as acyl donor in pyridine, aliphatic diols give predominantly the monoacetates.Glucose and isomeric hexoses give the 6-O-acetates in good yield. 6-Deoxy-sugars however, yield mixtures of acetates indicating that regioselectivity among the secondary hydroxyl groups are poor.Racemic trans-1,2-cyclohexanediol affords the (1R, 2R)-monoacetate in 44percent yield with greater than 90percent enantiomer ic purity. cis-1,2-cyclohexanediol and cis-1,2-cyclohexanedimethanol also give optically active monoacetates.

The beta-D-galactosyl-(1,3)-alpha-N-acetyl-D-galactosamine disaccharide is present in antifreeze glycoproteins (AFGPs). Analogs of this disaccharide including the beta-linked (1,3)-, (1,4)-, and (1,6)-galactosyl-N-acetyl galactosamine and the beta-(1,3)-galactosyl-galactoside were synthesized and evaluated for ice recrystallization inhibition (IRI) activity. The results from this study demonstrate that the b-linked-(1,4) disaccharide exhibits more potent IRI activity than the native b-linked-(1,3) disaccharide. The C2 N-acetyl group of the disaccharide does not affect IRI activity but in monosaccharides, the presence of the C2 N-acetyl group decreases IRI activity. The current study will facilitate the design of potent small-molecule ice recrystallization inhibitors.

The NagZ class of retaining exo-glucosaminidases play a critical role in peptidoglycan recycling in Gram-negative bacteria and the induction of resistance to beta-lactams. Here we describe the concise synthesis of 2-azidoacetyl-2-deoxy-5-fluoro-beta-D-glucopyranosyl fluoride as an activity-based proteomics probe for profiling these exo-glycosidases. This active-site directed reagent covalently inactivates this class of retaining N-acetylglucosaminidases with exquisite selectivity by stabilizing the glycosyl-enzyme intermediate. Inactivated Vibrio cholerae NagZ can be elaborated with biotin or a FLAG-peptide epitope using the Staudinger ligation or the Sharpless-Meldal click reaction and detected at nanogram levels. This ABPP enabled the profiling of the Pseudomonas aeruginosa proteome and identification at endogenous levels of a tagged protein with properties consistent with those of PA3005. Cloning of the gene encoding this hypothetical protein and biochemical characterization enabled unambiguous assignment of this hypothetical protein as a NagZ. The identification and cloning of this NagZ may facilitate the development of strategies to circumvent resistance to beta-lactams in this human pathogen. As well, this general strategy, involving such 5-fluoro inactivators, may prove to be of general use for profiling proteomes and identifying glycoside hydrolases of medical importance or having desirable properties for biotechnology.

Alkaline metalloendopeptidase (metalloprotease) AP1 (48 kDa) from Vibrio sp. isolated from the intestine of a five-barred goatfish (Parupeneus trifasciatus) was reported in our previous paper to produce AP2 (36 kDa) by releasing a peptide fragment (molecular mass of about 12 kDa) from the C-terminal end of AP1 by autodigestion. AP1 strongly agglutinated fish (flounder, Paralichthys olivaceus) and rabbit erythrocytes, and weakly chicken erythrocytes. In contrast, AP2 had no significant hemagglutinating activity toward any erythrocytes tested, except for weak activity on flounder erythrocytes, suggesting that the C-terminal region of AP1 may be required for the strong hemagglutinating activity. The optimum temperature for the hemagglutinating activity of AP1 was found to be lower than that for the proteolytic activity. At acidic pHs (below pH 7.5), the hemagglutinating activity of AP1 decreased, and its pH profile resembled that of the proteolytic activity. The hemagglutinating activity of AP1 was not observed in the presence of o-phenanthroline or synthetic and proteinous substrates, but different kinds of saccharides and lipids had no effect. While the proteolytic activity of AP1 was not affected by CaCl2, the hemagglutinating activity of AP1 decreased with increases in CaCl2 concentrations. These results suggested that the hemagglutinating activity of these proteases (AP1 and AP2) was most likely caused by their proteolytic action on erythrocyte cell surfaces.

Cationized dimers + of 2-acetamido-2-deoxy-D-glucose, 2-acetamido-2-deoxy-D-mannose, and 2-acetamido-2-deoxy-D-galactose were generated by fast atom bombardment (FAB) using different alkali cations and glycerol, S-valerolactame, and diethanolamine matrices.From their unimolecular decomposition (metastable ions) mainly two kinds of ions are observed resulting from the retention of the cation either by the amino sugar (ion a) or/and by the matrix (ion b).For a given hexosamine their relative abundance depends on the alkali cation and the matrixused.When the matrix is diethanolamine and the alkali cation is lithium or sodium, the N-acetylglucosamine stereoisomers can be differentiated by the relative abundances of ions a and b of the cationized dimer.
