The article discusses the study conducted by C. T. O'Loughlin and colleagues which describes the use of a synthetic compound meta-bromo-thiolactone (mBTL) for inhibition of the quorum-sensing receptors LasR and RhlR of the bacteria Pseudomonas aeruginosa. The authors of the study observed that mBTL is a potent inhibitor of both the production of the virulence factor pyocyanin and biofilm formation. They conclude that mBTL attenuates virulence and has potential as an antimicrobial drug.
