体外研究:
PqsR-IN-2 (Compound 19) inhibits pqs system with IC50 values of 298 ± 182.0 nM and 265 ± 3.4 nM against two different PA strains PAO1-L and PA14, respectively.PqsR-IN-2 significantly reduces pyocyanin production to 36% against a control of 0.1% DMSO at 3 × the IC50 value in P. aeruginosa strain PAO1-L. PqsR-IN-2 (0-100 μM, 16 h) shows no significant toxicity to A549 cells.
