Dysprosium(III) trifluoromethanesulfonate-catalyzed per-O-acetylation and regioselective anomeric de-O-acetylation of carbohydrates can be tuned by adjusting the reaction medium. In this study, the per-O-acetylation of unprotected sugars by using a near-stoichiometric amount of acetic anhydride under solvent-free conditions resulted in the exclusive formation of acetylated saccharides as anomeric mixtures, whereas anomeric de-O-acetylation in methanol resulted in a moderate-to-excellent yield. Reactions with various unprotected monosaccharides or disaccharides followed by a semi-one-pot sequential conversion into the corresponding acetylated glycosyl hemiacetal also resulted in high yields. Furthermore, the obtained hemiacetals could be successfully transformed into trichloroimidates after Dy(OTf)3-catalyzed glycosylation.

The present invention is directed to methods for inhibition of histone acetyltransferases using glycosaminoglycans. The invention is further directed to methods for treating disorders associated with hyperacetylation by administration of glycosaminoglycans to a patient in need thereof. In one preferred embodiment, the glycosaminoglycan is a heparin or heparan sulfate oligosaccharide. Studies show that removal of sulfate residues from the O-positions of either the uronic acid or the glucosamine did not eliminate the inhibitory activity of heparan sulfate. Since a majority of heparan sulfate binding proteins appear to require O-sulfation, molecules without certain O-sulfations can be used to inhibit HATs while not interacting with most known heparin-binding proteins. In addition, specific sequences of heparin/heparan sulfate can be used to specifically inhibit various HATs.

Pseudomonas aeruginosa flagellin protein recruits the mammalian host sialidase enzyme neuraminidase- 1 (NEU1) to remove sialic acid residues from the extracellular domain of the mammalian cell-surface protein MUC l (MUC l -ED), thereby exposing a cryptic binding site on the MUC l -ED protein backbone for flagellin binding. NEU1 -driven MUC l -ED desialylation rapidly increases P. aeruginosa adhesion to the airway epithelium. MUCl -ED desialylation also increases MUC l -ED cleavage and shedding from the cell surface, where desialylated, shed MUCl -ED competitively blocks P. aeruginosa adhesion to cell-associated MUCl -ED. Presented herein are data showing that exogenously-administered, deglycosylated MUCl -ED peptides reduced adhesion of P. aeruginosa to airway epithelial cells. Also presented are data showing that administration of P. aeruginosa to mice in combination with deglycosylated MUC 1 -ED decreased P. aeruginosa recovered from the lungs at 48 hr and 72 hr post-infection. Such findings are extended to the methods of treatment and prevention of bacterial infections defined herein.

Protein O-GlcNAcylation has been shown to play an important role in a number of biological processes, including regulation of the cell cycle, DNA transcription and translation, signal transduction, and protein degradation. O-GlcNAcase (OGA) is responsible for the removal of O-linked beta-N-acetylglucosamine (O-GlcNAc) from serine or threonine residues, and thus plays a key role in O-GlcNAc metabolism. Potent OGA inhibitors are useful tools for studying the cellular processes of O-GlcNAc, and may be developed as drugs for the treatment neurodegenerative diseases. In this study, Cu(I)-catalyzed ‘Click’ cycloaddition reactions between glycosyl azides and alkynes were exploited to generate inhibitory candidates of OGA. Enzymatic kinetic screening revealed that compound 7 was a potent competitive inhibitor of human O-GlcNAcase (Ki = 185.6 muM). Molecular docking simulations of compound 7 into CpOGA (Clostridium perfringens OGA) suggested that strong pi-pi stacking interaction between the compound and W490 considerably contributed to improving the inhibitory activity.

A lectin from the red marine alga Ptilota filicina (PFL) was isolated by affinity chromatography on cross-linked guar gum. PFL agglutinated native and papain-treated human erythrocytes with preference for type O erythrocytes. The lectin was inhibited by galactose and its derivatives. The most potent inhibitors were p-Nitrophenyl-N-acetyl-alpha-and beta-D-galactosaminide. Porcine stomach mucin, bovine submaxillary gland mucin and asialo bovine mucin were also inhibitory. The M(r) of PFL, determined by gel filtration, was 56,900. SDS-PAGE gave one band with a subunit M(r) of 19,320, indicating the native protein to be a trimer of apparently identical subunits. PFL was shown to be rich in acidic and hydroxyl amino acids but low in basic amino acids. The ten N-terminal amino acids were Asx-Thr-Lys-Thr-Tyr-Leu-Leu-Ala-.

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.

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.
