additional information identification of a class of PqsD inhibitors using a ligand-based approach. Simplification and rigidization leads to fragments with high ligand efficiencies. These small molecules repress HHQ and PQS production and biofilm formation in Pseudomonas aeruginosa. This validates PqsD as a target for the development of anti-infectives. No inhibition by 0.05 mM (3-[[4-(2-aminophenyl)-4-oxobutyl]amino]-3-oxopropyl)-2,4-dihydroxy-3,3-dimethylbutanamide, (2R)-N-(3-[[4-(2-aminophenyl)-4-hydroxybutyl]amino]-3-oxopropyl)-2,4-dihydroxy-3,3-dimethylbutanamide, (2-nitrophenyl)(phenyl)methanone, 1-(2-nitrophenyl)-1-phenylethanol and 2,2,2-trifluoro-1-(2-nitrophenyl)-1-phenylethanol Pseudomonas aeruginosa
