Quoromycin
Quoromycin is an orally active SmcR inhibitor with a Kd of 0.697 μM for Vibrio vulnificus SmcR. Quoromycin binds directly to SmcR, reduces its DNA-binding affinity, and inhibits the quorum sensing signaling pathway. Quoromycin is applicable to the research of Vibrio vulnificus infection.

Biological Activity
Quoromycin (1-50 μM) dose-dependently inhibits the binding of Vibrio vulnificus SmcR to the vvpE promoter DNA without altering SmcR protein levels[1].
Quoromycin (1-50 μM; 25 h) dose-dependently reduces elastase activity in Vibrio vulnificus without inhibiting bacterial growth[1].
Quoromycin (1-50 μM; 12 h) inhibits Vibrio vulnificus vvpE promoter activity with an IC50 of 322 nM[1].
Quoromycin (20 μM) reduces vvpE transcript levels, elastase activity, and exoprotease activity in wild-type Vibrio vulnificus to levels similar to an smcR mutant strain[1].
Quoromycin (1-100 μM; 3 h at 37 °C) dose-dependently reduces Vibrio vulnificus-induced cytotoxicity and bacterial adhesion to INT-407 human intestinal epithelial cells[1].
Quoromycin (20 μM) inhibits quorum sensing in Vibrio harveyi and reduces proteolytic activity in Vibrio anguillarum without inhibiting bacterial growth of either species[1].

Cell Line:INT-407 human intestinal epithelial cells infected with Vibrio vulnificus
-
Concentration:1, 10, 25, 50, 100 μM
-
Incubation Time:3 h at 37 °C
-
Result:Reduced Vibrio vulnificus-induced cytotoxicity in INT-407 cells in a dose-dependent manner, with 100 μM quoromycin returning LDH levels to non-infected control levels.
Reduced Vibrio vulnificus adhesion to INT-407 cells in a dose-dependent manner, with 50 μM quoromycin reducing adherent CFUs by half compared to controls.
Quoromycin (122 μg/kg; i.g.; single simultaneous dose with infection) significantly reduces V. vulnificus colonization in mouse small intestine, liver, and spleen, and prevents infection-associated tissue damage[1].
Quoromycin (30-122 μg/kg; i.g.; single dose) shows no acute in vivo cytotoxicity in healthy ICR female mice, with 100% 24-hour survival[1].
