產品介紹

Reparixin L-lysine salt is an allosteric inhibitor of chemokine receptor 1/2 (CXCR1/2) activation.

產品描述：

Reparixin L-lysine salt is an allosteric inhibitor of chemokine receptor 1/2 (CXCR1/2) activation.

靶點：

CXCR1wt:5.6 nM (IC50, in L1.2 cells);CXCR1Ile43Val:80 nM (IC50, in L1.2 cells);CXCR1:1 nM (IC50, in cells);CXCR2:～100 nM (IC50, in cells);CXCR

體外研究：

Reparixin is a potent functional inhibitor of CXCL8-induced biological activities on human PMNs with a marked selectivity (around 400-fold) for CXCR1, as shown in specific experiments on CXCR1/L1.2 and CXCR2/L1.2 transfected cells and on human PMNs. The efficacy of Reparixin is significantly lower in L1.2 cells expressing Ile43Val CXCR1 mutant (IC50 values of 5.6 nM and 80 nM for CXCR1 wt and CXCR1 Ile43Val, respectively). Reparixin is a non-competitive allosteric inhibitor of IL-8 receptors with a 400-fold higher efficacy in inhibiting CXCR1 activity than CXCR2

體內研究：

The pharmacokinetics and metabolism of Reparixin are investigated in rats and dogs after intravenous administration of [14C]-Reparixin L-lysine salt. Plasma protein binding of Reparixin is >99% in the laboratory animals and humans up to 50 μg/mL, but lower at higher concentrations. Although radioactivity is rapidly distributed into rat tissues, Vss is low (about 0.15 L/kg) in both rat and dog. Nevertheless, Reparixin is more rapidly eliminated in rats (t1/2~0.5 h) than in dogs (t1/2~10 h)
