IMP-2380
IMP-2380 is a NorA inhibitor that binds to the outward-open conformation of Staphylococcus aureus NorA. IMP-2380 enhances the activity of Ciprofloxacin against Methicillin-resistant (HY-121544) and Methicillin-sensitive Staphylococcus aureus. IMP-2380 inhibits Ciprofloxacin-induced SOS response and reduces prophage induction. IMP-2380 reduces bacterial burden in a mouse MRSA infection model in combination with Ciprofloxacin. IMP-2380 can be used for research on Methicillin-resistant Staphylococcus aureus (MRSA) infection.

Description
In Vitro
IMP-2380 (20 min) inhibits NorA-mediated EtBr efflux in S. aureus with an IC50 of 19 nM[1].
IMP-2380 (1 µM; 30 min) increases intracellular Ciprofloxacin accumulation in wild-type S. aureus[1].
IMP-2380 (1 µM; 6 h) enhances the killing effect of Ciprofloxacin against WT S. aureus by up to 10,000-fold[1].
IMP-2380 (30 µM; 6 h) inhibits Ciprofloxacin-induced prophage activation in S. aureus RN451[1].
IMP-2380 (1 µM; 72 h) completely blocks the emergence of spontaneous Ciprofloxacin tolerance in S. aureus SH1000[1].

Animal Model:C57BL/6 (female; 6-8 weeks; Envigo; n = 5 per group)[1]
-
Dosage:IMP-2380 30 mg/kg; ciprofloxacin 30 mg/kg
-
Administration:i.p.; single dose at 2 h after infection
-
Result:Produced no significant decrease in bacterial burden compared with vehicle.
Caused a 100-fold reduction in CFU count, with infections in 3 of 5 animals below the limit of detection of the assay combined with Ciprofloxacin.
