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 .

Cat. No.: HY-156456
CAS No.: 2762675-17-0
Elastase LasB-IN-1 (Compound 4b) has antibacterial activity. Elastase LasB-IN-1 (Compound 4b) is a selective elastase LasB inhibitor with an IC50 value of 76 nM .
Cat. No.: HY-163030
LasB-IN-1 (compound 5f) is a potent and orally active inhibitor of LasB (IC50 = 8.7 μM). LasB-IN-1 effectively attenuates elastase production and biofilm formation by P. aeruginosa while alleviating the inflammatory response through downregulating MAPK and NF-κB pathways. LasB-IN-1 is potential to be a novel anti-infective candidate against drug-resistant infections .
Cat. No.: HY-181647
CAS No.: 2762675-42-1
LasB-IN-3 is a protease elastase (LasB) inhibitor of Pseudomonas aeruginosa with an IC50 value of 8.5 nM. LasB-IN-3 shows an IC50 of 58.9 nM for the Met128Val mutant. LasB-IN-3 binds to active sites of wild-type and Met128Val mutant LasB, coordinates zinc ions, forms hydrogen bonds and CH-π interactions, and inhibits LasB proteolytic activity. LasB-IN-3 increases survival rate in LasB-induced acute lung injury mice models. LasB-IN-3 can be used for the research of Pseudomonas aeruginosa infection .
Cat. No.: HY-163481
CAS No.: 3033920-95-2
Antibiofilm agent-6 (Compound 26c) is a quorum sensing inhibitor with strong antibiofilm effects that can inhibit the fluorescence intensity of PAO1-lasB-gfp and PAO1-pqsA-gfp in a concentration-dependent manner. Antibiofilm agent-6 can inhibit the production of pyocyanin and rhamnolipid. Antibiofilm agent-6 aids helps ciprofloxacin (HY-B0356) effectively eliminate the living bacteria in a mouse model infected with P. aeruginosa PAO1 .
Cat. No.: HY-168948
CAS No.: 3063543-24-5
Quorum sensing-IN-9 (Compound 7d) inhibits quorum sensing in Pseudomonas aeruginosa by binding PqsR proteins. Quorum sensing-IN-9 inhibits the expression of quorum sensing systems related genes lasB, rhlA and pqsA, blocks the generation of virulence factors elastase, pyocyanin and rhamnolipid. Quorum sensing-IN-9 destorys the motility of P. aeruginosa, inhibits the biofilm formation, decreasing the virulence and pathogenicity of P. aeruginosa. Quorum sensing-IN-9 exhibits anti-infectious activity in Galleria mellonella larval model .

Targeted therapy! The Capetin Prize winning "Click Chemistry" can be used like this!Targeted therapy! 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
