2-heptyl-3-hydroxy-4(1H)-Quinolone (60 µM) increases secretion of the metabolite pyocyanin and the lectin PA-IL, as well as increases biofilm production in P. aeruginosa populations.[2]
2-heptyl-3-hydroxy-4(1H)-Quinolone (40 µM) reduces iron levels in P. aeruginosa growth media when used at a concentration and acts as an iron chelator in a Fe(III)-sulfate solution.[3]
