Heptyl α-D-mannosides grafted on a β-cyclodextrin core to interfere with Escherichia coli adhesion Vrije Universiteit Brussel KU Leuven
n-Heptyl α-D-mannoside (HM) has previously been identified as a nanomolar FimH antagonist able to prevent Escherichia coli adhesion. We have designed mono- and heptavalent glycoconjugates in which HM is tethered to β-cyclodextrin (β-CD) through short and long spacers. One-pot click or co-clicking procedures were developed to directly obtain the glycoconjugates from unprotected HM and β-CD precursors. These FimH antagonists were examined ...
