  Inhibition of Streptococcus suis Adhesion by Dendritic Galabiose Compounds at Low Nanomolar Concentration

  摘要：

  A series of mono-, di-, and tetravalent galablose (Ga1alpha1-4Gal) compounds were synthesized in good yields by coupling of a general carboxylic acid-bearing sugar building block to dendritic scaffolds based on the 3,5-di-(2-aminoethoxy)benzoic acid branching unit. Furthermore. a poly(amidoamine)- (PAMAM-) based dendritic galabioside was Synthesized containing eight galabiose units. All galabiosides were tested in a hemagglutination assay and a Surface plasmon resonance (SPR) competition assay in order to establish their potency in the binding to the bacterial Gram-positive pathogen Streptococcus suis. A monovalent cralabioside containing a short spacer was used as a reference compound in all the assays. Varations in the scaffold as well as in the spacer arms were introduced to determine their influence on the inhibition. The best inhibitor of hemagglutination was an octavalent galabioside with a minimal inhibitory concentration (MIC) of 0.3 nM, to the best of our knowledge the first, example of inhibition of bacterial binding by a soluble carbohydrate at a subnanomolar concentration.
