생물학적 활성

설명 SB225002는 CXCR2의 강력하고 선택적인 길항제로, CXCR2에 대한 인터루킨 IL-8 결합을 억제하는 데 있어 IC50 값이 22 nM이며, 테스트된 다른 7-TMRs 대비 150배 이상의 선택성을 보입니다.

시험관 내(In vitro) In vitro, SB225002 inhibits GROα-stimulated calcium mobilization, and potently inhibits human and rabbit neutrophil chemotaxis induced by both IL-8 and GROalpha. This compound substantially reduces the levels of phosphorylated ERK1/2, and decreases cell proliferation in WHCO1 cells. It also shows the antitumor activity as a microtubule inhibitor.
생체 내(In Vivo) In rabbits, SB225002 selectively blocks IL-8-induced neutrophil margination. In mouse intrahepatic cholangiocellular carcinoma model, this compound (1 mg/kg i.p.) suppresses the growth of transplanted subcutaneous tumors. In addition, it also displays long-lasting antinociceptive effects, and reduces TNBS-induced colitis in mouse models.

  • 방법

    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.

<p>(e, f) Administration of the selective CXCR2 antagonist SB225002 mitigated mechanical hyperalgesia and heat hyperalgesia in CCI rats. Antinociceptive effects of a single intrathecal (it.) injection of 20 µg SB225002 were observed at 1 h and disappeared at 2 h. Antinociceptive effects induced by a single injection of SB225002 at 40 µg were observed at 1 h and disappeared 6 h after injection. Injection of SB225002 (10 µg, i.t.) did not alter the PWT and PWL of CCI rats. N = 6 rats for each group, *p < .05, compared to NS group. PWL: paw withdraw latency; PWT: paw mechanical withdrawal thresholds.</p>

(G) Concentration-dependent inhibition of cell proliferation in SKOV3 cells (* P ≤ 0.005) treated with SB225002 (0.625, 1.25, 2.5 and 5 μM) for 2 days was revealed using XTT cell proliferation assay. (H) Western blot analysis confirmed that TAK1/NFκB signaling was inhibited dose-dependently in SKOV3 cells upon treatment with SB225002 (1.25 and 2.5 μM) as compared with untreated control.
