Abstract
Attachment of lipophilic groups is an important post-translational modification of proteins, which involves the coupling of one or more anchors such as fatty acids, isoprenoids, phospholipids, or glycosylphosphatidyl inositols. To study its impact on the membrane partitioning of hydrophobic peptides or proteins, we designed a tyrosine-based trifunctional linker. The linker allows the facile incorporation of two different functionalities at a cysteine residue in a single step. We determined the effect of the lipid modification on the membrane partitioning of the synthetic α-helical model peptide WALP with or without here and in all cases below; palmitoyl groups in giant unilamellar vesicles that contain a liquid-ordered (Lo ) and liquid-disordered (Ld ) phase. Introduction of two palmitoyl groups did not alter the localization of the membrane peptides, nor did the membrane thickness or lipid composition. In all cases, the peptide was retained in the Ld phase. These data demonstrate that the Lo domain in model membranes is highly unfavorable for a single membrane-spanning peptide.

Abstract
UNLABELLED L-selectin mediates extravasation of leukocytes from blood into the surrounding tissue during inflammation and is therefore a therapeutical target in certain overwhelming immune reactions. In this study, we characterized an L-selectin specific blocking DNA aptamer with respect to nucleotide composition and target binding. Introduction of deletions and nucleotide exchanges resulted in an optimized DNA sequence but preservation of the IC50 in the low nanomolar range. The inhibitory potential was significantly increased when the aptamer was displayed as a di- and trimer connected via appropriate linker length. Similar to monoclonal antibodies, trimer yielded picomolar IC50 values in a competitive binding assay. In comparison to the monovalent aptamer, the trivalent assembly reduced PBMC interactions to L-selectin ligands 90-fold under shear and exerted superior inhibition of PBMC rolling in vivo. In conclusion, our work demonstrates the feasibility of optimizing aptamer sequences and shows that multivalent ligand presentation enables superior adhesion receptor targeting. FROM THE CLINICAL EDITOR During inflammation, leukocytes extravasate from blood vessels under chemotaxic signals. The presence of L-selectin on endothelium acts as a mediator for the extravasation process. In this study, the authors investigated an L-selectin specific blocking DNA aptamer in various forms, as inhibitors to leukocyte binding and extravasation. This new approach confirmed the potential use of aptamers in clinical setting.

Abstract
We report on the design and synthesis of molecules having E- and P-selectins blocking activity both in vitro and in vivo. The GlcNAc component of the selectin ligand sialyl Lewis(X) was replaced by an acyclic tether that links two saccharide units. The minimization of intramolecular dipole-dipole interactions and the gauche effect would be at the origin of the conformational bias imposed by this acyclic tether. The stereoselective synthesis of these molecules, their biochemical and biological evaluations using surface plasmon resonance spectroscopy (SPR), and in vivo assays are described. Because the structure of our analogues differs from the most potent E-selectin antagonists reported, our acyclic analogues offer new opportunities for chemical diversity.

Abstract
The glycocalyx of eukaryotic cells is composed of glycoconjugates, which carry highly complex oligosaccharide portions. To elucidate the biological role and function of the glycocalyx in cell-cell communication and cellular adhesion processes, glycomimetics have become targets of glycosciences, which resemble the composition and structural complexity of the glycocalyx constituents. Here, we report about the synthesis of a class of oligosaccharide mimetics of a high-mannose type, which were obtained by mannosylation of spacered mono- and oligosaccharide cores. These carbohydrate-centered cluster mannosides have been targeted as inhibitors of mannose-specific bacterial adhesion, which is mediated by so-called type 1 fimbriae. Their inhibitory potencies were measured by ELISA and compared to methyl mannoside as well as to a series of mannobiosides, and finally to the polysaccharide mannan. The obtained results suggest a new interpretation of the mechanisms of bacterial adhesion according to a macromolecular rather than a multivalency effect.

Abstract
Recent progress has been made in constructing synthetic multivalent carbohydrate ligands targeted at known or probable multivalent carbohydrate ligand receptors. Multivalency can dramatically compensate for the weak affinities of individual carbohydrate ligand moieties. Multivalent branched ligand mimetics have been described bearing multiple mannoside, galactoside, lactoside and Sialyl Lewis X (SLe(x)) moieties. New methods for polymeric backbone construction have provided glyco-polymers of defined and controllable size. Promising examples of multivalent ligands giving significant increases in binding potency are being pursued. These types of agents have extensive therapeutic potential in treating infectious diseases or host abnormalities, and also offer exciting potential as drug-conjugate cell-targeting agents.

Abstract
The crystal structure of a bivalent glycocluster containing aromatic amides reveals that alkylation of secondary amides alters amide configuration and thus carbohydrate presentation. This also facilitates non covalent interactions (azide-azide, carbonyl-pyranose and aromatic-pyranose) and thus carbohydrate-carbohydrate stacking.

Abstract
Coating of azobenzene chromophore with multivalent sugar ligands has been accomplished. Such sugar coating allows the study of the isomerization properties of this chromophore in aqueous solutions. The predominantly cis-isomer-containing photostationary state (PS) mixture of these azobenzene derivatives is found to be stable for hours. The rate constants for their isomerization, as well as the Arrhenius activation energies, are determined experimentally. An assessment of the lectin binding properties of the lactoside bearing isomeric azobenzene derivatives, by isothermal calorimetric methods, reveals the existence of an unusual cooperativity in their binding to lectin peanut agglutinin. Thermodynamic parameters evaluated for the trans and the PS mixture are discussed, in detail, for the lactoside bearing bivalent azobenzene derivative.

Abstract
Selectins constitute a family of proteins that mediate leukocyte tethering and rolling along the vascular endothelium by recognizing various carbohydrate ligands in response to inflammation. To test the hypothesis that multivalent binding of selectins to their ligands is the molecular basis for achieving sufficient binding forces, we have performed this flow chamber study. Selectin-containing Chinese hamster ovarial cells (CHO-E) bind and roll along a support-fixed phospholipid membrane containing a defined concentration of a synthetic Sialyl Lewisx (sLex) glycolipid ligand. Ligands are either homogeneously distributed, or arranged in defined lateral clusters, as illustrated here for the first time. The lateral glycolipid clusters which appear as recognition motifs are essential for mediating cell rolling. Furthermore, the transition from firm cell adhesion to cell rolling depends on the site density of ligands. Rolling velocity shows little dependence on shear forces within a broad range. As we found out that cells do not roll along the model membranes with homogeneous ligand distribution, our results therefore support the hypothesis of multivalent binding events. Since these investigations suggest that lipid-anchored sLex, functionally embedded in a lipid matrix, can mediate cell rolling, this study demonstrates the relationship between dynamic glycolipid binding to selectins with the hypothesis of multivalency of binding for the first time.

Abstract
AbstractLeukocyte rolling is the earliest observable event in their recruitment from the circulation to inflamed tissue. This rolling is mediated largely by interaction between the selectin family of adhesion molecules and their glycosylated ligands. Although the nature of these ligands and their interaction with the selectins is not fully understood, it is accepted that expression of fucosylated sialylated glycans such as sialyl Lewisx (sLex) is required for function. Despite findings that sLex inhibits binding of leukocytes to E-selectin in vitro, and has beneficial effects in inflammatory disease models, inhibition of E-selectin–dependent leukocyte rolling in vivo has not been described. Functional overlap between the selectins has been noted and reduction of rolling by E-selectin antibodies only occurs if P-selectin is absent or blocked. We demonstrate that leukocyte rolling velocity in tumor necrosis factor alpha (TNFα)-stimulated mouse cremaster is increased following treatment with either sLex or the sLex-mimetic CGP69669A and that rolling is dramatically reduced if CGP69669A is applied in the presence of anti–P-selectin antibody. These effects are characteristic of E-selectin antagonism. In contrast, surgically stimulated (L- or P-selectin–dependent) rolling is unaffected by either sLex or CGP69669A. Our data demonstrate that CGP69669A is an effective and selective antagonist of E-selectin in vivo.

Abstract
Leukocyte rolling is the earliest observable event in their recruitment from the circulation to inflamed tissue. This rolling is mediated largely by interaction between the selectin family of adhesion molecules and their glycosylated ligands.

Abstract
Traditional structure activity relationship studies (SAR) have led to the development of numerous sialyl Lewis(x) analogs in the search for potential antiinflammatory agents. However, these methods do not take into account cluster or multivalent effects. Reported herein is the chemoenzymatic synthesis of di-, tetra-, and octa-valent sLe(x) ligands scaffolded on dendrimers. Hypervalent L-lysine cores with covalently attached 2-acetamido-2-deoxy-D-glucose (N-acetylglucosamine, GlcNAc) residues were chemically prepared and enzymatically transformed into sLe(x) containing dendrimers so that multivalency, and its role in selectin-sLe(x) interactions may be evaluated. This work constitutes another successful enzymatic synthesis of sLe(x) and represents the first example of GlcNAc elongation on a synthetic dendrimer scaffold. These sLe(x) dendrimers are currently being investigated as selectin antagonists.

Abstract
The synthesis and binding properties of a new family of high affinity alpha-D-mannopyranoside ligands are described. The synthesis of the new multivalent ligands is based on the scaffolding of multiantennary branches of L-lysine residues having electrophilic N-chloroacetylated end groups as core structures. An alpha-D-mannopyranoside with p-substituted aryl aglycon ending with a thiol group was prepared and covalently attached to each of the branches of the dendritic structures. The resulting glycodendrimers with 2 (12), 4 (14), 8 (16), and 16 (18) mannoside residues were tested for their relative inhibitory potency by solid-phase enzyme-linked lectin assays (ELLA) using methyl and p-nitrophenyl alpha-D-mannopyranosides as standards. Concentrations necessary for 50% inhibition (IC50s) of binding of yeast mannan to Jack bean phytohemagglutinin (Canavalia ensiformis, concanavalin A) and to pea lectin (Pisum sativum) were determined. Analogous mannosylated copolyacrylamides were also prepared for comparison. The IC50 values were also plotted as a function of dendrimer valencies. The inhibitions showed 16-mer 18 to be approximately 600- and 2000-fold more potent than methyl alpha-D-mannopyranoside, and 66- and 1383-fold more potent than p-nitrophenyl alpha-D-mannopyranosides with Con A and pea lectins, respectively. Even when these numbers are expressed relative to single mannopyranoside residues per dendrimers, the relative potencies against the aromatic mannoside are still 4- and 86-fold better against Con A and pea lectins. These results unequivocally indicate that the optimum inhibitory binding properties of the new mannosylated dendrimers vary with both dendrimers and lectin valencies.

Abstract
Classical multivalent neoglycoproteins have been widely used to study a great number of carbohydrate-protein interactions. The synthesis of other neoglycoconjugates with various shapes, valencies, and conformations has reached considerable levels of sophistication and holds promise as a new tool for glycobiology and biomedical applications. Within the last few years, advances have been made towards both the syntheses and understanding of the antigenic properties of water-soluble glycopolymers. Some of these glycopolymers are finding applications as inhibitors of microbial adhesins and as carriers for drug delivery to specific cells. Novel dendritic carbohydrate structures are emerging as potent ligands for carbohydrate-binding proteins.

Abstract
Many processes mediated by protein-carbohydrate interactions involve multivalent low-affinity binding, which is inherently difficult to study. New structural templates for the generation of multivalent carbohydrate displays have recently been developed, and tailored multivalent saccharide derivatives can now be used to study and modulate a wide variety of biological recognition events.
