Multivalent calixarene-based C-fucosyl derivative: a new Pseudomonas aeruginosa biofilm inhibitor

The first example of multivalent conjugate in which four α- l- C-fucosyl units are clustered by means of a calix[4]arene platform was designed as a new potential Pseudomonas aeruginosa biofilm inhibitor. The anti-biofilm activity of the synthesized compound ( 6) against PAO1 strain was assayed and i...

Zusammenfassung:	The first example of multivalent conjugate in which four α- l- C-fucosyl units are clustered by means of a calix[4]arene platform was designed as a new potential Pseudomonas aeruginosa biofilm inhibitor. The anti-biofilm activity of the synthesized compound ( 6) against PAO1 strain was assayed and it was found to be dose-dependent. The presence of the fucose cluster improves the biofilm inhibitor efficiency as proven by the lower inhibitor activity of the analogous glycyl-calix[4]arene derivative ( 3) lacking in the fucose moieties.
