PV-DPD-19
PV-DPD-19 is an autoinducer-2 (AI-2) quorum sensing inhibitor. PV-DPD-19 reduces AI-2 production and inhibits the expression of multiple MSCRAMMs. In co-culture systems with Staphylococcus aureus, PV-DPD-19 decreases the production of pyocyanin and Elastase in Pseudomonas aeruginosa. PV-DPD-19 impairs the adhesion ability of Staphylococcus aureus to lung epithelial cells. PV-DPD-19 inhibits biofilm formation of Pseudomonas aeruginosa (MBIC50 = 27 μg/mL) and Staphylococcus aureus (MBIC50 = 35 μg/mL). PV-DPD-19 shows no cytotoxicity in both in vitro lung epithelial cell models and in vivo Galleria mellonella larva models.

Biological Activity
PV-DPD-19 inhibits biofilm formation by *Pseudomonas aeruginosa* (MBIC50 = 27 μg/mL) and *Staphylococcus aureus* (MBIC50 = 35 μg/mL)[1].
PV-DPD-19 significantly reduces the adhesion rate of *Staphylococcus aureus* to human A549 epithelial cells by approximately 30%[1].
PV-DPD-19 (2 mM; overnight, 8 h) significantly reduces AI-2 production in *Staphylococcus aureus* SH1000 as determined by the *Vibrio harveyi* bioluminescence assay[1].
PV-DPD-19 (20-40 μM; 16 h) reduces pyocyanin production in *Pseudomonas aeruginosa* PAO1 in a dose-dependent manner[1].
PV-DPD-19 (3.12-200 μM; 24 h) shows no cytotoxicity against epithelial cell line A549[1].
