CAY10711 is a substituted diamine that produces rapid bactericidal activity against both Gram-positive and Gram-negative bacteria, including methicillin-resistant S. aureus (MRSA) and stationary-phase bacteria. It displays MIC99 values of 2.9, 11.5, 2.9, and 2.9 μM against S. aureus RN4220, P. aeruginosa PAO1, E. coli ANS1, and MRSA 10082B, respectively. CAY10711 reduces biofilm formation and promotes biofilm dispersal in P. aeruginosa. It is synergistic with kanamycin and has limited adverse effects against mammalian cells or C. elegans development, survival, or reproduction.
YXL-13 is a highly effective inhibitor of Pseudomonas aeruginosa (PAO1), with an IC50 value of 3.686 μM. It effectively hinders the expression of virulence factors and inhibits biofilm formation in PAO1. Moreover, YXL-13 significantly diminishes both the pathogenicity and drug resistance of PAO1 by inhibiting the quorum sensing (QS) system. Thus, YXL-13 holds great potential for studying antibacterial properties [1].
Quorum Sensing-IN-2(compound 23e)是一款不影响细菌生长的群体感应抑制剂,具有减少细菌致病性的功能。该化合物在抑制细菌感染方面表现出效力,同时具有极低的溶血活性。在铜绿假单胞菌PAO1引起的菌血症模型中,Quorum Sensing-IN-2与环丙沙星共同作用,显示了协同效应。
