Quorum sensing-IN-7

Quorum sensing-IN-7 (HSL 4) is a potent quorum sensing inhibitor that targets the CviR receptor at Leu 72 and Gln 95. It effectively suppresses homoserine lactone production and biofilm formation in C. violaceum at 0.25-1 mg/mL, making it a valuable tool for studying anti-virulence strategies and biofilm-related infections in vitro.
