Biological Activity

Reparixin is a noncompetitive allosteric inhibitor of IL-8 (CXCL8) activation of CXCR1 and CXCR2 chemokine receptors with IC50 of 1 and 100 nM, respectively. Reparixin effectively decreased systolic blood pressure and increased the blood flow. Treatment with reparixin significantly counteracts secondary degeneration by reducing oligodendrocyte apoptosis, migration to the injury site of neutrophils and ED-1-positive cells.

Method i.p.
Cell Lines Six-week-old BALB/c male nude mice
Concentrations 15 mg/kg
Incubation Time once a day
Results Interestingly, we found that using Reparixin alone could also inhibit the migration and invasion ability of HNSCC cells. These results suggested that Reparixin may block both the exogenous IL-8 and autocrine IL-8 of tumor cells.
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
