GTPL547 is a potent quorum sensing system antagonist specifically targeting the PqsR (MvfR) transcriptional regulator in Pseudomonas aeruginosa (IC50 = 12 nM). By halting the PQS-mediated gene transcription cascade, it completely suppresses the secretion of lethal virulence factors like pyocyanin and the irreversible assembly of biofilms, providing a critical lead compound for tackling multidrug-resistant infections.
