The use of a bi-functional linker, containing an alkyne and an alkene, allows the protecting group free conjugation of reducing sugars to thiols via a double click process. Firstly the linker is attached to the sugar via one-pot glycosyl azide formation and Cu-catalysed azide-alkyne cycloaddition. Photochemical thiol-ene click reaction then allows conjugation to a range of thiols, including cysteine residues of peptides.

The biantennary oligosaccharide analogue beta-D-GlcpNAc-(1 ? 2)-alpha-D-Manp-(1 ? 3)[beta-D-GlcpNAc-(1 ? 2)-alpha-D-Manp-(1 ? 6)]-beta-D-Manp-O(CH2)8COOMe (3) is a potential substrate for N-acetylglucosaminyltransferases (GlcNAcTs) III-V which are present in mammalian cells. The di-O-methylated analogue of 3, beta-D-GlcpNAc-(1 ? 2)-[4-O-methyl-alpha-D-Manp]-(1 ? 3)-[beta-D-GlcpNAc-(1 ? 2)-[6-O-methyl-alpha-D-Manp]-(1 ? 6)]-beta-D-Manp-O(CH2)8COOMe (5), was prepared by a block synthesis approach involving sequential addition of two O-methylated disaccharide donors to a protected central beta-D-Man residue. The OH groups acted on by GlcNAcT-IV and -V are protected from glycosylation in 5 since they are present as their methyl ethers. Pentasaccharide 5 was found to be an excellent substrate for GlcNAcT-III (EC 2.4.1.144) from rat kidney with K(m) = 0.15 mM. The product formed by incubation of 5 with a rat kidney extract, in the presence of UDP-GlcNAc, was isolated, structurally characterized by NMR spectroscopy and confirmed to be the expected di-O-methyl hexasaccharide where a beta-D-GlcpNAc residue had been added to OH-4 of the central beta-D-Manp unit.

Human lactoferrin (LF) specifically binds to human monocytic leukemia cell line THP-1 cells differentiated into macrophages, and it has been suggested that the poly-N-acetyllactosaminyl saccharide chains of LF are involved. We partially purified and characterized LF-binding proteins with affinity for polylactosamines from THP-1 cells. LF-binding activity was solubilized by nonionic detergent Triton X-100 from THP-1 cell membrane, and subjected to affinity chromatography using an LF-Sepharose column. LF- binding activity, detected by ligand blotting assay, was elated and further fractionated by affinity chromatography using a Sepharose column coupled with band 3, a polylactosaminyl chain-containing glycoprotein of human erythrocyte membrane. LF-binding activity was separated into three fractions (frs. B1, B2, and B3). These fractions exhibited hand 3-binding activity as detected by ligand blotting assay. Dodecylsulfate-polyacrylamide get electrophoresis of frs. B1, B2, and B3, followed by detection of LF-binding activity on Western blots, indicated that frs. B1, B2, end B3 contained LF-binding proteins with a molecular mass of 35, 50 and 80, and 35 – 37 kDa, respectively. Binding of LF to each of the fractions on the dot blots was partially inhibited by LF oligosaccharides, band 3 oligosaccharides and lacto-N-neotetraose, each containing di-N-acetyllactosaminyl or analogous structure, Galbeta ? 4GlcNAcbeta1 ? 3Galbeta1 ? 4GlcNAc (or Glc). These results suggest that the 35, 50 and/or 80, and 35 – 37 kDa proteins on THP-1 cells are LF-binding proteins with poly-lactosamine-binding ability.

Primaquine (PQ) is the only drug used to prevent relapse of malaria due to P. vivax and P. ovale, by eradicating the dormant liver form of the parasite (hypnozoites). The side-effects associated with PQ limits is uses in treatment of malaria. To overcome the premature oxidative deamination and to increase the life span of drug in the biological system, the novel glyco-conjugates of PQ were synthesized by coupling of primaquine with hexoses in phosphate buffer. The saccharide part of the hybrid molecules thought to direct the drug to the liver, where hypnozoites resides. All the synthesized compounds were fully characterized and evaluated for their radical curative activities. The three compounds viz glucoside (15a), galactoside (15b) and mannoside (15c) with high activity were tested for their activity in rhesus monkeys where the most active compound 15b showed twofold activity (100% radical curative activity at 1.92 mmol/kg) than the standard drug PQ diphosphate (3.861 mmol/kg). It is proposed that results from these studies may be advantageous to develop a new potent tissue schizonticide antimalarial compound.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 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.

Amide cis-trans isomerization (CTI) in methyl 2-deoxy-2-acylamido-d- glucopyranosides was investigated by 1H and 13C NMR spectroscopy. Singly 13C-labeled methyl 2-deoxy-2-formamido-d- glucopyranoside (MeGlcNFm) anomers provided standard 1H and 13C chemical shifts and 1H-1H and 13C-13C spin-coupling constants for cis and trans amides that are detected readily in aqueous solution. Equipped with this information, doubly 13C-labeled methyl 2-deoxy-2-acetamido-d-glucopyranoside (MeGlcNAc) anomers were investigated, leading to the detection and quantification of cis and trans amides in this biologically important aminosugar. In comparison to MeGlcNFm anomers, the percentage of cis amide in aqueous solutions of MeGlcNAc anomers is small (?23% for MeGlcNFm versus ?1.8% for MeGlcNAc at 42 C) but nevertheless observable with assistance from 13C-labeling. Temperature studies gave thermodynamic parameters deltaG, deltaH, and deltaS for cis-trans interconversion in MeGlcNFm and MeGlcNAc anomers. Cis/trans equilibria depended on anomeric configuration, with solutions of alpha-anomers containing less cis amide than those of beta-anomers. Confirmation of the presence of cis amide in MeGlcNAc solutions derived from quantitative 13C saturation transfer measurements of CTI rate constants as a function of solution temperature, yielding activation parameters Eact, deltaG ?, deltaH-, and deltaS ? for saccharide CTI. Rate constants for the conversion of trans to cis amide in MeGlcNFm and MeGlcNAc anomers ranged from 0.02 to 3.59 s-1 over 31-85 C, compared to 0.24-80 s-1 for the conversion of cis to trans amide over the same temperature range. Energies of activation ranged from 16-19 and 19-20 kcal/mol for the cis ? trans and trans ? cis processes, respectively. Complementary DFT calculations on MeGlcNFm and MeGlcNAc model structures were conducted to evaluate the effects of an acyl side chain and anomeric structure, as well as C2-N2 bond rotation, on CTI energetics. These studies show that aqueous solutions of GlcNAc-containing structures contain measurable amounts of both cis and trans amides, which may influence their biological properties.
