Active efflux influences the potency of quorum sensing inhibitors in Pseudomonas aeruginosa.

Abstract excerpt

Many bacteria regulate gene expression through a cell-cell signaling process called quorum sensing (QS). In proteobacteria, QS is largely mediated by signaling molecules known as N-acylated L-homoserine lactones (AHLs) and their associated intracellular LuxR-type receptors. The design of non-native small molecules capable of inhibiting LuxR-type receptors (and thereby QS) in proteobacteria is an active area of...
