Research Areas:
Pseudomonas quinolone signal (PQS) is a quorum-sensing signaling molecule produced by Pseudomonas aeruginosa. The synthesis of Pseudomonas quinolone signal relies on the las quorum-sensing system, and its biological activity is associated with the rhl system. Pseudomonas quinolone signal regulates the expression of the virulence gene lasB. Additionally, Pseudomonas quinolone signal plays roles in iron acquisition, cytotoxicity, outer-membrane vesicle biogenesis, and host immune modulation .

Research Areas:
Methyl 2-amino-5-bromobenzoate (Compound 8/12) is a biochemical reagent. Methyl 2-amino-5-bromobenzoate can be used to synthesize 2-benzamidobenzoic acid, a known FabH inhibitor. Derivatives of methyl 2-amino-5-bromobenzoate also inhibit PqsD, the pqs quorum sensing (QS) system, of Pseudomonas aeruginosa .
Cat. No.: HY-179389
Research Areas:
XDS-23 is a selective biofilm inhibitor with an IC50 of 1.26 µM against Pseudomonas aeruginosa. XDS-23 exerts a dual inhibitory effect on the LasI/LasR System (las) and Pseudomonas Quinolone Signal System (pqs). XDS-23 suppress the production of key virulence factors including elastase, pyocyanin, and extracellular polysaccharides. XDS-23 exhibits synergistic antibacterial activity and can enhance the efficacy of multiple antibiotics in both in vitro and in vivo models, while maintaining a favorable safety profile. XDS-23 can be employed for research in combating biofilm-mediated drug-resistant P. aeruginosa infections .
Cat. No.: HY-155479
CAS No.: 3033007-79-0
PqsR-IN-3 (compound 16e) is a selective inhibitor of the pqs system (IC50=3.7 μM) and its associated virulence factor pyocyanin (IC50=2.7 μM). PqsR-IN-3 inhibits bacterial biofilm synthesis and is significantly cytotoxic against Pseudomonas aeruginosa. PqsR-IN-3 has synergistic effects with several antibiotics, such as Ciprofloxacin (HY-B0356) and Tobramycin (HY-B0441) .
Cat. No.: HY-173270
Antibacterial synergist 3 is a dual-acting inhibitor of biofilm (IC50 of PAO1: 0.40 μM and IC50 of PA14: 1.45 μM). Antibacterial synergist 3 reduces virulence production by inhibiting the quorum sensing (QS) system and induces iron deficiency in P. aeruginosa PAO1. Antibacterial synergist 3 enhances the efficacy of Tobramycin (HY-B0441) and Ciprofloxacin (HY-B0356) in a mouse wound infection model. Antibacterial synergist 3 can be used for the research of P. aeruginosa infections .

The Nobel Prize winning "Click Chemistry" can be used like this!A suitable model is crucial in drug screening experiments. Organs can mimic the three-dimensional functional structure of internal organs, have similar spatial organization to corresponding organs, maintain some key characteristics, and reproduce some physiological functions. They are widely used for modeling and personalized drug screening physiological functions.2025-02-06
