4、(Kd)體外研究 Navarixin is a potent, allosteric antagonist of both CXCR1 and CXCR2, with Kd values of 41 nM forcynomolgus CXCR1 and 0.20 nM, 0.20 nM, 0.08 nM for mouse, rat and cynomolgus monkey CXCR2,respectivelly 1. Navarixin (1 nM) reduces CXCL8 potency in stimulating Ba/F3-hCXCR2 chemotaxis.Navarixin

5、 (3 nM) significantly inhibits the potency and efficacy of CXCL1-induced neutrophils (PMN)chemotaxis. Navarixin (300 nM) significantly decreases chemokine potency and slightly decreases maximalcell movement for Ba/F3-CXCR1 cells 2. Navarixin (25 M) is sufficient to block IL-8-mediated CXCR2activatio

Inrats, Navarixin (0.1-3 mg/kg p.o.) suppresses the pulmonary neutrophilia (ED=1.8 mg/kg) and increase inbronchoalveolar lavage (BAL) mucin content (ED50=0.1 mg/kg) induced by intratracheal (i.t.)

8、ls are resuspended at 1106/mL in assay buffer (phenol red free-RPMI 1640 supplementedwith 2% FBS). Human neutrophils are resuspended at 2 106/mL in the same assay buffer containing 5%FBS. CXCL1 binds only CXCR2 with high affinity, whereas CXCL8 binds both CXCR1 and CXCR2 with highaffinity. Chemoattr

9、actants (30 L) diluted in assay buffer are dispensed into the bottom wells of disposablemicrochemotaxis plates, which are then covered with filter. Cells are preincubated with Navarixin (1-300 nM)in a CO2 incubator for 90 min. Cell aliquots (25 L) are applied to each spot on the filter. After incuba

Migrated cells in thebottom wells are transferred to a Microlite luminometer plate, and 25 L of ATPlite one-step are added toeach well. After incubation at room temperature for 10 min, luminescence intensity
