A concise route for construction of the ACDE ring skeleton in calyciphylline A type alkaloids was developed using an intramolecular [5+2] cycloaddition reaction of an oxidopyrylium species bearing a tetrasubstituted olefin. Key to the success of this reaction was the combination of acid and base, which accelerated the construction of this skeleton containing a spiro ring and vicinal quaternary carbon centers. The resultant tricyclic ADE ring compound was converted to an ACDE ring model through C?H oxidation and an aza-Wittig reaction.

Macrocyclic compounds play an important role in many research fields including drug discovery and development, bioorganic chemistry, and materials sciences. Carbohydrate-based macrocycles are important compounds with unique structures and many potential applications. In this study, we have designed and synthesized a series of 1,2,3-triazole linked and pyranose embedded macrocycles in short steps through the copper (I) catalyzed azide and alkyne cycloaddition reactions (CuAACs). Eight non-symmetrical glucosamine based and bis-triazole linked macrocycles have been synthesized starting from the readily available N-acetyl-d-glucosamine. These triazole-linked glycomacrocycles showed remarkable reaction rate accelerations for CuSO4 mediated azide and alkyne cycloaddition reactions in aqueous mixtures. Several azides including a sugar azide, which react sluggishly with alkynes, have been accelerated with the synthesized macrocycles. The benzoylated macrocycles with three methylene linkage at anomeric positions were the most effective among the eight macrocycles.

We measured the affinity of more than 20 sugars with concanavalin A (ConA) by an optical biosensor (surface plasmon resonance sensor) using asialofetuin (ASF) as an immobilized binding partner of ConA. We determined kinetic parameters of the effects of sugars on the dissociation of ConA from ASF quantitatively, and the structural requirements of the functional groups of sugars for binding with ConA. We found that the affinity of ConA for sugars is dependent on its conformation induced by interaction with the binding partner. In addition, the results showed that optical biosensor system is well mimics the interaction of ConA with sugars in biomembrane.

Enzymatic synthesis of trisaccharides from N-acetylsucrosamine and lactose utilizing the transgalactosylation activity of Aspergillus oryzae beta-galactosidase provided two reaction products. Structure analyses by various 2D NMR spectroscopy and MS indicated that the products were beta-D-fructofuranosyl beta-D-galactopyranosyl-(1?6)-2-acetamido-2-deoxy-alpha-D-glucopyranoside and beta-D-galactopyranosyl-(1?6)-beta-D-fructofuranosyl-(2?1)-2-acetamido-2-deoxy-alpha-D-glucopyranoside. Moreover, J-resolved-HMBC experiments indicated that the conformations around the glycosidic bonds of these trisaccharides were very similar. Examination about the pH and thermal stabilities of the glycosidic bonds in the GlcNAc?Fru moiety of the two trisaccharides indicated apparent difference.

Lactoferrin is a non-heme iron-binding glycoprotein with multiple health-beneficial functions including antimicrobial, antioxidant, anticarcinogenic, and immunomodulatory effects. There is emerging evidence that neutrophils may serve as targets of lactoferrin in vivo, and here we show how recombinant human lactoferrin (rhLf) can contribute to this regulation. Indeed, our results demonstrate that rhLf binds efficiently to human neutrophils and induces a variety of early cellular responses such as mobilization of intracellular Ca2+, remodeling of actin cytoskeleton, and degranulation (release of lysozyme and myeloperoxidase). In addition, rhLf facilitates lectin-induced H2O2 production and stabilization of lectin-induced cellular aggregates. The role of calcium signaling seems to be essential for rhLf-induced activation of neutrophils, as Ca2+-chelators inhibit degranulation response while lectin-induced H2O2 production correlates significantly with cytoplasmic Ca2+ elevation. Taken together, our findings justify that rhLf can activate neutrophil functions in a calcium-dependent manner and hence, can potentiate innate immune responses.

A high-yield preparatory procedure for the synthesis of p-nitrophenyl 2-acetamido-2-deoxy-beta-D-galacto-hexodialdo-1,5-pyranoside (2) using the galactose oxidase from Dactylium dendroides in a batch reactor was developed. Enzymatic recognition of this aldehyde and the respective uronic acid 3 obtained by NaClO2 oxidation was studied using a set of 36 fungal beta-N-acetylhexosaminidases from Acremonium, Aspergillus, Penicillium and Talaromyces genera. The aldehyde 2 was readily hydrolysed by all tested beta-N-acetylhexosaminidases but neither the uronic acid 3 nor its methyl ester 4 were accepted. Molecular modelling with docking into the active centre of the beta-N-acetylhexosaminidase from Aspergillus oryzae revealed that the aldehyde 2 is processed as a C-6 geminal diol by the enzyme. The aldehyde 2 was tested for transglycosylation reactions using GlcNAc as an acceptor. The beta-N-acetylhexosaminidase from Talaromyces flavus gave the best yields (37%) of the transglycosylation product 2-acetamido-2-deoxy-beta-D-galacto- hexodialdo-1,5-pyranosyl-(1?4)-2-acetamido-2-deoxy-D-glucopyranose, which was oxidised in situ to yield the final product 2-acetamido-2-deoxy-beta-D- galactopyranosyluronic acid-(1?4)-2-acetamido-2-deoxy-D-glucopyranose (6). Compounds 3 and 6 were shown to be high-affinity ligands for two natural killer cell activation receptors, NKR-P1A and CD69. For the latter receptor they turned out to be among the best ligands described so far. This increase was obviously due to the presence of a carboxy moiety.

In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption.

A highly convergent strategy for the synthesis of several derivatives of the lipid A of Rhizobium sin-1 has been developed. The synthetic derivatives are 2-aminogluconate 3 and 2-aminogluconolactone 4, both of which lack C-3 acylation. These derivatives were obtained by the preparation of disaccharides in which the two amino groups and the C-3? hydroxy group could be modified individually with acyl or beta-hydroxy fatty acyl groups. Detailed NMR spectroscopy and MS analysis of 3 and 4 revealed that, even under neutral conditions, the two compounds equilibrate. The synthetic compounds lack the proinflammatory effects of Escherichia coli lipopolysaccharide (LPS), as indicated by an absence of tumor necrosis factor production. Although 3 and 4 were able to antagonize E. coli LPS, they were significantly less potent than the synthetic compound 2, which is acylated at C-3, and R. sin-1 LPS; these results indicate that the beta-hydroxy fatty acyl group at C-3 contributes to the antagonistic properties of R. sin-1 LPS. Based on a comparison of the biological responses of the synthetic lipid A derivatives with those of the R. sin-1 LPS and lipid A, the 3-deoxy-D-manno-octulosonic moieties appear to be important for the optimal antagonization of enteric LPS-induced cytokine production.
