A Pseudomonas aeruginosa PQS quorum-sensing system inhibitor with anti-staphylococcal activity sensitizes polymicrobial biofilms to tobramycin (2022)
Journal Article
Murray, E. J., Dubern, J.-F., Chan, W. C., Chhabra, S. R., & Williams, P. (2022). A Pseudomonas aeruginosa PQS quorum-sensing system inhibitor with anti-staphylococcal activity sensitizes polymicrobial biofilms to tobramycin. Cell Chemical Biology, 29(7), 1187-1199.e6. https://doi.org/10.1016/j.chembiol.2022.02.007

As single- and mixed-species biofilms, Staphylococcus aureus and Pseudomonas aeruginosa cause difficult-to-eradicate chronic infections. In P. aeruginosa, pseudomonas quinolone (PQS)-dependent quorum sensing regulates virulence and biofilm developmen...

Timing is everything – impact of naturally occurring Staphylococcus aureus AgrC cytoplasmic domain adaptive mutations on auto-induction (2019)
Journal Article
Sloan, T. J., Murray, E., Yokoyama, M., Massey, R. C., Chan, W. C., Bonev, B., & Williams, P. (2019). Timing is everything – impact of naturally occurring Staphylococcus aureus AgrC cytoplasmic domain adaptive mutations on auto-induction. Journal of Bacteriology, 201(20), Article e00409-19. https://doi.org/10.1128/jb.00409-19

Mutations in the polymorphic Staphylococcus aureus agr locus responsible for quorum sensing (QS) dependent virulence gene regulation occur frequently during host adaptation. In two genomically closely related S. aureus clinical isolates exhibiting ma...

Journal Article
Zapotoczna, M., Murray, E. J., Hogan, S., O'Gara, J. P., Chhabra, S. R., Chan, W. C., O'Neill, E., & Williams, P. (2017). 5-Hydroxyethyl-3-tetradecanoyltetramic acid represents a novel treatment for intravascular catheter infections due to Staphylococcus aureus. Journal of Antimicrobial Chemotherapy, 72(3), 744-753. https://doi.org/10.1093/jac/dkw482

Objectives: Biofilm infections of intravascular catheters caused by Staphylococcus aureus may be treated with catheter lock solutions (CLSs). Here we investigated the antibacterial activity, cytotoxicity and CLS potential of 5-hydroxyethyl-3-tetradec...

A series of 3-oxo-C 12 -HSL, tetramic acid, and tetronic acid analogues were synthesized to gain insights into the structural requirements for quorum sensing inhibition in Staphylococcus aureus. Compounds active against agr were noncompetitive inhibi... Read More about Targeting Staphylococcus aureus quorum sensing with nonpeptidic small molecule inhibitors.
