Nitroxoline is an antibiotic[1] that has been in use in Europe for about fifty years, and has proven to be very effective at combating biofilm infections. Nitroxoline was shown to cause a decrease in the biofilm density of P. aeruginosa infections, which would allow access to the infection by the immune system in vivo.[2] It was shown that nitroxoline functions by chelating Fe2+ and Zn2+ ions from the biofilm matrix; when Fe2+ and Zn2+ were reintroduced into the system, biofilm formation activity was restored. The biofilm degradation ability is comparable to EDTA derivatives, but this drug has a history of human use in clinical settings and therefore has a precedent with which to allow its use against “slimy” biofilm infections.
