Antibiofilm agent-19
Antibiofilm agent-19 is an antibiofilm agent with iron-chelating activity. Antibiofilm agent-19 potently inhibits biofilm formation by wild-type PAO1 and the hyper-biofilm mutant strain PAO1-ΔwspF. Antibiofilm agent-19 promotes the formation of c-di-GMP G-quadruplexes and disrupts iron acquisition systems. It can be used in studies on antibacterial adjuvants.

Biological Activity
Antibiofilm agent-19 (compound 11f) (0.156-2.5 μM; 24 h) potently inhibits biofilm formation by P. aeruginosa PAO1-ΔwspF (at 0.156 μM) and wild-type PAO1 (at 2.5 μM) without affecting bacterial growth[1].
Antibiofilm agent-19 (0-2.5 μM; 12-16 h) reduces the production of extracellular polymeric substances in P. aeruginosa, with the strongest efficacy observed in the PAO1-ΔwspF strain with high c-di-GMP levels[1].
Antibiofilm agent-19 (0.125-50 μM; 24 h) disrupts iron homeostasis in P. aeruginosa by promoting siderophore secretion, and this effect is reversed by the addition of excess Fe3+ [1].
Antibiofilm agent-19 (6.25-200 μM; 24 h) exhibits excellent biocompatibility, with no significant cytotoxicity against Vero cells or RAW264.7 macrophages even at concentrations as high as 200 μM[1].
