产品名称：SB225002
产品描述：
| 产品描述 | SB225002 is a potent and selective CXCR2 antagonist inhibiting interleukin IL-8 binding to CXCR2. |
| 靶点活性 | CXCR2:22 nM |
| 体外活性 | SB225002表现出长效的镇痛效果,并减少小鼠模型中TNBS诱导的结肠炎.在兔子中,SB225002选择性阻断IL-8诱导的嗜中性粒细胞的边缘化.在小鼠肝内胆管细胞癌模型中,1 mg/kg i.p. SB225002抑制皮下移植肿瘤的生长. |
| 体内活性 | SB225002显示了作为微管抑制剂的抗肿瘤活性。SB225002大大降低了磷酸化ERK1/2的水平,并降低了WHCO1细胞的细胞增殖。SB225002在体外实验中,抑制GROα刺激的钙动员,并有效地抑制由IL-8和GROα诱导的人和兔嗜中性粒细胞趋化性。 |
| 激酶实验 | Radioligand Binding Experiments: Assays are performed in 96-well microtiter plates where the reaction mixture contains 1.0 μg/ml membrane protein in 20 mM Bis-Tris-propane, pH 8.0, with 1.2 mM MgSO4, 0.1 mM EDTA, 25 mM NaCl, and 0.03% CHAPS and SB 225002 (10 mM stock in Me2SO) added at the indicated concentrations, the final Me2SO concentration is <1% under standard binding conditions. Binding is initiated by addition of 0.25 nM 125I-IL-8 (2,200 Ci/mmol). After 1-h incubation at room temperature the plate is harvested using a Tomtec 96-well harvester onto a glass fiber filtermat blocked with 1% polyethyleneimine, 0.5% BSA and washed three times with 25 mM NaCl, 10 mM Tris·HCl, 1 mM MgSO4, 0.5 mM EDTA, 0.03% CHAPS, pH 7.4. The filter is dried, sealed in a sample bag containing 10 ml of Wallac 205 Betaplate liquid scintillation fluid, and counted with a Wallac 1205 Betaplate liquid scintillation counter. |
| 细胞实验 | Three esophageal squamous cell carcinoma cell lines WHCO1, WHCO5, and WHCO6 originally established from surgical biopsies of primary esophageal squamous cell carcinomas are cultured in DMEM containing 10% FCS at 37°C in a humidified atmosphere of 5% CO2. MTT assays are carried out using the Cell Proliferation kit I. Briefly, 1.5 × 103 cells are plated in 96-well plates in a final volume of 180 μL DMEM per well. SB 225002 (antagonist of CXCR2, 400 nM) is added to cells and 0.001% DMSO (solvent) is added as a control. After the indicated incubation period, 18 μL of the MTT labeling reagent (final concentration 0.5 mg/mL) is added to each well and incubated for 4 hours in a humidified atmosphere. One hundred eighty microliters of the solubilization solution are added to each well and the plates were left overnight at 37°C. The spectrophotometric absorbance of samples is measured at 595 nm using a microtiter plate reader.(Only for Reference) |
