SB225002是趋化因子受体CXCR2高校选择性抑制剂,IC50值为22nM,对CXCR1及其他7-TMRs跨膜受体抑制力弱或无。
SB225002 is a potent and selective non-peptide inhibitor of CXCR2 with IC50 of 22 nM and >150-fold selectivity over CXCR1 and four other 7-TMRs. Causes inhibition of IL-8 and GROα-mediated calcium mobilization in HL60 cells (IC50 values are 8 and 10 nM respectively). Prevents IL-8-induced neutrophil chemotaxis in vitro and sequestration in vivo. In addition, SB225002 reduces MPO activity, IL-1β, MIP-2, and keratinocyte-derived chemokine (KC) levels. Further studies suggest that SB225002 decreases the expression of vascular endothelial growth factor, inducible NOS (NO synthase), and Cox-2 (cyclooxygenase-2 proteins) in colon tissue.

例如,已知某工具药用于小鼠的剂量为88 mg/kg , 则用于大鼠的剂量换算方法:将88 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到该药物用于大鼠的等效剂量44 mg/kg。
