SB 265610 is a potent CXCR2 antagonist that inhibits CINC-1-mediated Ca2+ mobilization with IC50 value of 3.4nM [1] [2].
CXCR2 is an integral membrane protein that specifically binds and responds to cytokines of the CXC chemokine family.
In isolated rat neutrophils stimulated with rat CINC-1, SB 265610 inhibited Ca2+ mobilization induced by CINC-1 with IC50 value of 3.4 nM in a dose-dependent way, while inhibited Ca2+ mobilization induced by C5a only with IC50 value of 6.8uM, which showed selectivity of the antagonist for CXCR2 [1]. In equilibrium saturation binding studies, SB265610 inhibited the binding of interleukin-8 without affecting the Kd. While, IL-8 couldn’t prevent binding of SB265610. SB265610 is an allosteric inverse agonist at the CXCR2 receptor [2].
In a hyperoxia rat model, newborn rats increased lung neutrophil content. Treatment with SB-265610 reduced hyperoxia-induced neutrophil accumulation in bronchoalveolar lavage and whole lung myeloperoxidase accumulation [1].

工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
