| Hazard Information | Back Directory | [Description]
Reparixin (CAS 266359-83-5) is a noncompetitive allosteric inhibitor of IL-8 (CXCL8) activation of CXCR1 and CXCR2 chemokine receptors (IC50?= 1 and 100 nM, respectively). It blocks a number of activities related to IL-8 signaling, including leukocyte recruitment (IC50?= 1 nM) without affecting receptor activation induced by other CXCR1 and CXCR2 agonists.1?In spontaneously hypertensive rats, 5 mg/kg reparixin administered daily for three weeks was shown to reduce blood pressure by inhibiting hypertension-related mediators.2?It attenuates inflammatory responses and promotes recovery of function after traumatic lesion to the spinal cord.3?Reparixin blockade (100 nM) of CXCR1 has also been used to deplete a cancer stem cell population in human breast cancer cell lines?in vitro.4 | [Uses]
