Antibiofilm agent-23
Antibiofilm agent-23 is a PqsR-targeting agent, iron chelator, biofilm inhibitor, biofilm dispersant, and anti-virulence agent. Antibiofilm agent-23 selectively binds to PqsR, disrupts the pqs quorum sensing pathway, restricts bacterial iron acquisition, induces intracellular iron deficiency, reduces pyocyanin, elastase, and rhamnolipid production, impairs biofilm formation, and disperses mature biofilms. Antibiofilm agent-23 exhibits low cytotoxicity and shows antibacterial synergy with Ciprofloxacin (HY-B0356) in Caenorhabditis elegans infection models. Antibiofilm agent-23 can be used for the research of biofilm-associated Pseudomonas aeruginosa infections.

Biological Activity
Antibiofilm agent-23 (compound 5) (1.25-20 μM; 24 h) inhibits P. aeruginosa PAO1 biofilm formation in a dose-dependent manner, with inhibition rates of 51.2% and 58.3% at 10 and 20 μM, respectively[1].
Antibiofilm agent-23 (1.25-20 μM; 2 h) disperses mature P. aeruginosa PAO1 biofilms, significantly increasing planktonic bacterial counts at concentrations ≥ 1.25 μM[1].
Antibiofilm agent-23 (1.25-20 μM; 24 h) reduces the production of P. aeruginosa virulence factors, including elastase (44.6% reduction at 20 μM), rhamnolipid (19.7% reduction at 20 μM), and pyocyanin (66.7% reduction at 20 μM)[1].
Antibiofilm agent-23 selectively inhibits the pqs QS pathway in P. aeruginosa PAO1-pqsA-gfp reporter strain in a dose-dependent manner, while showing weak or no inhibition of the las and rhl pathways[1].
Antibiofilm agent-23 (20 μM) significantly elicits siderophore production, increasing pyoverdine (PVD) by 11.1-fold and pyochelin (PCH) by 1.5-fold in P. aeruginosa PAO1[1].
Antibiofilm agent-23 (20 μM) in combination with sub-MIC Ciprofloxacin (HY-B0356) shows synergistic antibacterial activity against P. aeruginosa PAO1 and MDR clinical isolates (1121, 1129, 1167, and FB)[1].
Antibiofilm agent-23 (up to 100 μM; 48 h) shows low cytotoxicity in HEK293 cells[1].

Animal Model:Caenorhabditis elegans (L4 larval stage) infected with P. aeruginosa PAO1[1]
-
Dosage:20 μM
-
Administration:48 h
-
Result:Prolonged survival from 24 h to 30 h post-infection (25.1% survival at 48 h).
Yielded a higher survival rate (33.3%) when combined with Ciprofloxacin at 48 h compared to Ciprofloxacin alone (25.1%). Showed no obvious adverse effect on uninfected C. elegans survival over 48 h at 20 and 100 μM.
