摘要
LectinA (LecA) from Pseudomonas aeruginosa is an established virulence factor. Glycoclusters that target LecA and are able to compete with human glycoconjugates present on epithelial cells are promising candidates to treat P.aeruginosa infection. A family of 32 glycodendrimers of generation0 and 1 based on a bifurcated bis-galactoside motif have been designed to interact with LecA. The influences both of the central multivalent core and of the aglycon of these glycodendrimers on their affinity toward LecA have been evaluated by use of a microarray technique, both qualitatively for rapid screening of the binding properties and also quantitatively (K-d). This has led to high-affinity LecA ligands with K-d values in the low nanomolar range (K-d=22nm for the best one).
