Abstract
N‐Acetylneuraminic acid (sialic acid, Neu5Ac) is one of a large, diverse family of nine‐carbon monosaccharides that play roles in many biological functions such as immune response. Neu5Ac has previously been identified as a potential biomarker for the presence and pathogenesis of cardiovascular disease (CVD), diabetes and cancer. More recent research has highlighted acetylated sialic acid derivatives, specifically Neu5,9Ac2, as biomarkers for oral and breast cancers, but advances in analysis have been hampered due to a lack of commercially available quantitative standards. We report here the synthesis of 9‐O‐ and 4‐O‐acetylated sialic acids (Neu5,9Ac2 and Neu4,5Ac2) with optimisation of previously reported synthetic routes. Neu5,9Ac2 was synthesised in 1 step in 68 % yield. Neu4,5Ac2 was synthesised in 4 steps in 39 % overall yield. Synthesis was followed by analysis of these standards via quantitative NMR (qNMR) spectroscopy. Their utilisation for the identification and quantification of specific acetylated sialic acid derivatives in biological samples is also demonstrated.

Abstract
![]()
The 1,5-HAT–1,2-(ester)alkyl
radical migration (Surzur–Tanner
rearrangement) radical/polar sequence triggered by alkoxyl radicals
has been studied on a series of C-glycosyl substrates
with 3-C-(α,β-d,l-glycopyranosyl)1-propanol
and C-(α-d,l-glycopyranosyl)methanol
structures prepared from chiral pool d- and l-sugar.
The use of acetoxy and diphenoxyphosphatoxy as leaving groups provides
an efficient construction of 10-deoxy-1,6-dioxaspiro[4.5]decane and
4-deoxy-6,8-dioxabicyclo[3.2.1]octane frameworks. The alkoxyl radicals
were generated by the reaction of the corresponding N-alkoxyphthalimides with group 14 hydrides [n-Bu3SnH(D) and (TMS)3SiH], and in comparative terms,
the reaction was also initiated by visible light photocatalysis using
the Hantzsch ester/fac-Ir(ppy)3 procedure.
Special attention was devoted to the influence of the relative stereochemistry
of the centers involved in the radical sequence on the reaction outcome.
The addition of BF3•Et2O as a catalyst
to the radical sequence resulted in a significant increase in the
yields of the desired bicyclic ketals.

Abstract
An efficient and simple approach for stereoselective synthesis of β-Kdo C-glycosides was described, which relies on easily available peracetylated anomeric acetate or anomeric 2-pyridyl sulfide to couple with carbonyl compounds via SmI2-mediated Reformatsky reactions. The utility of this methodology is exemplified by the streamlined synthesis of a practical β-Kdo C-glycoside with an anomeric aminopropyl linker to conjugate with other biomolecules for further biological studies.

Abstract
Glycoconjugates are an important class of biomolecules that regulate numerous biological events in cells. However, these complex, medium-size molecules are metabolically unstable, which hampers detailed investigations of their functions as well as their potential application as pharmaceuticals. Here we report sialidase-resistant analogues of ganglioside GM3 containing a monofluoromethylene linkage instead of the native O-sialoside linkage. Stereoselective synthesis of CHF-linked disaccharides and kinetically controlled Au(I)-catalyzed glycosylation efficiently furnished both stereoisomers of CHF-linked as well as CF 2 - and CH 2 -linked GM3 analogues. Like native GM3, the C-linked GM3 analogues inhibited the autophosphorylation of epidermal growth factor (EGF) receptor induced by EGF in vitro. Assay of the proliferation-enhancing activity toward Had-1 cells together with NMR-based conformational analysis showed that the (S)-CHF-linked GM3 analogue with exo-gauche conformation is the most potent of the synthesized compounds. Our findings suggest that exo-anomeric conformation is important for the biological functions of GM3.

Abstract
Native insulin is susceptible to biophysical aggregation and fibril formation, promoted by manual agitation and elevated temperatures. The safety of the drug and its application to alternative forms of administration could be enhanced through the identification of chemical modifications that strengthen its physical stability without compromising its biological properties. Complex polysialic acids (PSAs) exist naturally and provide a means to enhance the physical properties of peptide therapeutics. A set of insulin analogues site-specifically derivatized with sialic acid were prepared in an overall yield of 50-60%. Addition of a single or multiple sialic acids conferred remarkable enhancement to the biophysical stability of human insulin while maintaining its potency. The time to the onset of fibrillation was extended by more than 10-fold relative to that of the native hormone. These results demonstrate that simplified sialic acid conjugates represent a viable alternative to complex natural PSAs in increasing the stability of therapeutic peptides.

Abstract
A set of three mannopyranoside possessing identical 1,1'-biphenyl glycosidic pharmacophore but different aglyconic atoms were synthesized using either a palladium-catalyzed Heck cross coupling reaction or a metathesis reaction between their corresponding allylic glycoside derivatives. Their X-ray structures, together with their calculated 3D structures, showed strong indicators to explain the observed relative binding abilities against E. coli FimH as measured by a improved surface plasmon resonance (SPR) method. Amongst the O-, C-, and S-linked analogs, the C-linked analog showed the best ability to become a lead candidate as antagonist against uropathogenic E. coli with a Kd of 11.45 nM.

Abstract
Preventing bacterial adhesion to host cells is a provocative and alternative approach to traditional antibiotic treatments given the increasing microbial resistance. A brief overview of common antibiotic treatments is described in light of their respective resistance and remaining susceptibility. This strategy has been seriously considered in the context of adherent-invasive infections in Crohn's disease and urinary tract infections in particular. The adhesions of various pathogenic Escherichia coli strains to host cells are primarily mediated through carbohydrate-protein interactions involving bacterial organelles called fimbriae that can recognize specific glycoconjugate receptors on host cells. Of particular interest are the FimH and PapG fimbriae, which bind to mannosylated glycoproteins and glycolipids of the galabiose series, respectively. Therefore, blocking FimH- and PapG-mediated bacterial adhesion to uroepithelial cells by high-affinity carbohydrate antagonists constitutes a challenging therapeutic target of high interest. This is of particular interest since bacterial adhesion to host cells is a parameter unlikely to be the subject of bacterial mutations without affecting the carbohydrate ligand binding interactions at the basis of the recognition and infection processes. To date, there have been several families of potent FimH antagonists that include natural O-linked as well as unnatural analogues of α-d-mannopyranosides. These observations led to a thorough understanding of the intimate binding site interactions that helped to reveal the so-called "tyrosine gate mechanism" at the origin of the strong necessary interactions with sugar-possessing hydrophobic aglycones. By modification of the aglycones of single monosaccharidic d-mannopyranosides, it was possible to replace the natural complex oligomannoside structure by simpler ones. An appealing and successful series of analogues have been disclosed, including nanomolecular architectures such as dendrimers, polymers, and liposomes. In addition, the data were compared to the above multivalent architectures and confirmed the possibility of working with small sugar candidates. This Account primarily concentrates on the most promising types of FimH inhibitors belonging to the family of α-C-linked mannopyranosides. However, one of the drawbacks associated with C-mannopyranosides has been that they were believed to be in the inverted chair conformation, which is obviously not recognized by the E. coli FimH. To decipher this situation, various synthetic approaches, conformational aspects, and restrictions are discussed using molecular modeling, high-field NMR spectroscopy, and X-ray analysis. These combined techniques pointed to the fact that several α-C-linked mannopyranosides do exist in the required 4C1 chair conformation. Ultimately, recent findings in this growing field of interest culminated in the identification of drug candidates that have reached clinical phase I.

Abstract
We report on the design of pH-switchable monolayers allowing a reversible and ordered introduction of affinity reagents on sensor surfaces. The principal layer building blocks consist of α-(4-amidinophenoxy)alkanes decorated at the ω-position with affinity ligands. These spontaneously self-assemble on top of carboxylic acid terminated SAMs to form reversible homo or mixed monolayers (rSAMs) that are tunable with respect to the nature of the head group, layer order and stability while featuring pH responsiveness and the dynamic nature of noncovalent build assemblies. We show that this results in a range of unique biosensor features. As a first example a sialic acid rSAM featuring strong lectin affinity is here used to sense hemagglutinin and influenza virus (H5N1) at the pM and fM level by in situ ellipsometry in a fully reversible fashion. We believe that the rSAM concept will find widespread use in surface chemistry and overall for boosting sensitivity in affinity biosensors.

Abstract
Boric acid catalyzes methyl esterification of certain sugar acids (sialic acid, deaminated neuraminic acid) and related natural products (quinic acid) quite cleanly in some cases. However, closely related sugar acids (glucuronic acid, 3-deoxy-d-manno-oct-2-ulosonic acid) failed to esterify under the same conditions. Factors governing this dichotomy are discussed.

Abstract
Two novel N-acetylneuraminic acid derivatives, luciferyl N-acetylneuraminic acid (1) and luciferyl 4,7-di-O-methyl-N-acetylneuraminic acid (2), were designed and synthesized as substrates for the rapid detection of influenza virus neuraminidase. The sensitivity and specificity of the assays with compound 1 or 2 as the substrate for detection of neuraminidases from influenza virus (H1N1 and H5N1) and bacteria (A. ureafaciens and C. perfringens) were evaluated. Compound 1 was sensitive to neuraminidases from both influenza virus and bacteria. Bioluminescent assays with this compound with H1N1 and H5N1 neuraminidases were approximately 20- and 16-fold more sensitive, respectively, than the fluorescent method with the commercial substrate 4-MUNANA. In contrast, compound 2 was only sensitive to the neuraminidases from influenza virus, showing approximately 10- and 8-fold greater sensitivity than 4-MUNANA for the detection of H1N1 and H5N1 neuraminidases, respectively. The data showed that compound 2 could be used in assays for detection of an influenza viral neuraminidase.

Abstract
Sialidase-resistant ganglioside analogs having similar biological activities to natural gangliosides are expected to be important probes for clarifying the biological functions of gangliosides. Focusing on difluoromethylene-linked (CF2-linked) and methylene-linked (CH2-linked) α(2,3)sialylgalactose as a core structure of sialidase-resistant ganglioside mimics, we have developed novel, stereocontrolled, and efficient methodologies to synthesize C-sialosides based on Ireland-Claisen rearrangement. These methods were employed to synthesize CF2-linked GM4. The CF2-linked GM4 inhibited human sialidases NEU2 and NEU4 with IC50 values of 754 and 930 μM, respectively, and strongly inhibited human lymphocyte proliferation in the same concentration range as natural GM4.
