  • The presence of water improves reductive openings of benzylidene acetals with trimethylaminoborane and aluminium chloride
    作者:Andrei A. Sherman、Yuri V. Mironov、Olga N. Yudina、Nikolay E. Nifantiev

    efficient for the reductive openings of the cyclic benzylidene acetals with Me(3)N x BH(3) in tetrahydrofurane than the AlCl(3) alone. Under proposed conditions, the dioxane-type 4,6-O-bezylidene acetals of hexopyranosides give regioselectively the corresponding 4-hydroxy,6-O-benzyl derivatives in excellent yields. Reductive openings of the dioxolane-type 3,4-O-benzylidene acetals of galactopyranoside are

    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 LewisX 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

    with up to 73% yield and 8.4:1 stereoselectivity, was realized when 2,3,4-unprotected galactose derivatives and TBSOTf were used as acceptors and promoter, respectively. Sialylation of 2-(trimethylsilyl)ethyl 6-O-tert-butyldiphenylsilyl-β-d-galactopyranoside (3f) gave the best result, and the resultant Neu5Ac α(2→3)Gal disaccharide was successfully used in the synthesis of ganglioside GM3.

  • A New Approach to Explore the Binding Space of Polysaccharide-Based Ligands: Selectin Antagonists
    作者:Mickael Calosso、Daniel Charpentier、Marc Vaillancourt、Mohammed Bencheqroun、Gabrielle St-Pierre、Brian C. Wilkes、Yvan Guindon

    The discovery of molecules that interfere with the binding of a ligand to a receptor remains a topic of great interest in medicinal chemistry. Herein, we report that a monosaccharide unit of a polysaccharide ligand can be replaced advantageously by a conformationally locked acyclic molecular entity. A cyclic component of the selectin ligand Sialyl Lewis(x), GlcNAc, is replaced by an acyclic tether, tartaric esters, which link two saccharide units. The conformational bias of this acyclic tether originates from the minimization of intramolecular dipole-dipole interaction and the gauche effect. The evaluation of the binding of these derivatives to P-selectin was measured by surface plasmon resonance spectroscopy. The results obtained in our pilot study suggest that the discovery of tunable tethers could facilitate the exploration of the carbohydrate recognition domain of various receptors.
