Inhibition of Pseudomonas aeruginosa biofilms with a glycopeptide dendrimer containing D-amino acids

Abstract

The C-fucosyl peptide dendrimer D-FD2 (CFuc-lys-pro-leu)4(Lys-phe-lys-leu)2Lys-his-leu-NH2 was prepared as the D-amino acid containing stereoisomer of the Pseudomonas aeruginosa biofilm inhibitor FD2. D-FD2 showed lower affinity for the fucose specific lectin LecB, was also active as a biofilm inhibitor and in addition showed high stability towards proteolysis with pure proteases and in human serum.
