Development of Potent Inhibitors of Pyocyanin Production in Pseudomonas aeruginosa
摘要:
The development of new approaches for the treatment of antimicrobial-resistant infections is an urgent public health priority. The Pseudomonas aeruginosa pathogen, in particular, is a leading source of infection in hospital settings, with few available treatment options. In the context of an effort to develop antivirulence strategies to combat bacterial infection, we identified a series of highly effective small molecules that inhibit the production of pyocyanin, a redox-active virulence factor produced by P. aeruginosa. Interestingly, these new antagonists appear to suppress P. aeruginosa virulence factor production through a pathway that is independent of LasR and RhlR.

Antivirulence strategies to combat Pseudomonas aeruginosa, are described. One strategy encompasses synthesis of a series of compounds that inhibit the production of pyocyanin, a redox-active virulence factor produced by this pathogen. A related strategy encompasses synthesis of compounds that inhibit the two P. aeruginosa quorum-sensing receptors, LasR and RhlR, inhibit production of pyocyanin, and inhibit biofilm formation.
