| IC50 | 42 nM | 3 nM | ||||
| Cell experiment[1]: | |
| Cell lines | Human melanoma cell line (A375SM ) |

| Reacting condition | 1 μg/ml, 72h |
| Applications | SCH-479833 or SCH 527123 inhibited the melanoma cell proliferation, chemotaxis, and invasive potentialin vitro.Treatment of melanoma cells with SCH-479833 or SCH 527123 also inhibited tumor growth. Histologic and histochemical analyses showed significant (P<0.05) decreases in tumor cell proliferation and microvessel density in tumors. Moreover, we observed a significant increase in melanoma cell apoptosis in SCH-479833- or SCH 527123-treated animals compared with controls. |
| Animal experiment[1]: | |
| Animal models | Male BALB/c mice, 20-25 g |
| Dosage form | Sch-527123 was suspended in 0.4% methylcellulose |
| Application | Sch 527123 was bound with high affinity to the CXCR2 receptors of mouse (Kd=0.20 nM), rat (Kd=0.20 nM), and cynomolgus monkey (Kd=0.08 nM) and was a potent antagonist of CXCR2-mediated chemotaxis (IC50~3– 6 nM). In contrast, Sch 527123 bound to cynomolgus CXCR1 with lesser affinity (Kd=41 nM) and weakly inhibited cynomolgus CXCR1-mediated chemotaxis (IC50 ~1000 nM). Oral treatment with Sch-527123 blocked pulmonary neutrophilia (ED50=1.2 mg/kg) and goblet cell hyperplasia (32–38% inhibition at 1–3 mg/kg) in mice following the intranasal lipopolysaccharide (LPS) administration. In rats, Sch-527123 suppressed the pulmonary neutrophilia (ED=501.8 mg/kg) and increase in bronchoalveolar lavage (BAL) mucin content (ED 50≤ 0.1 mg/kg) induced by intratracheal (i.t.) LPS. Sch-527123 also suppressed the pulmonary neutrophilia (ED50=1.3 mg/kg), goblet cell hyperplasia (ED 50=0.7 mg/kg), and increase in BAL mucin content (ED50<1 mg/kg) in rats after i.t. administration of vanadium pentoxide. In cynomolgus monkeys, Sch-527123 reduced the pulmonary neutrophilia induced by repeat bronchoscopy and lavage (ED50=0.3 mg/kg). |
| Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

SCH-527123 is a novel, selective CXC chemokine receptor 2 (CXCR2) antagonist.
SCH-527123 was able to suppress CXCR2-mediated signal transduction as shown through decreased phosphorylation of the NF-κB/mitogen-activated protein kinase (MAPK)/AKT pathway [1].
Cells were treated with increasing concentrations of SCH-527123 for 72 hours and showed dose-dependent growth inhibitory activity with IC50 (72 h) values ranging from 18 to 40 μmol/L. Importantly the IL-8–overexpressing cells showed a higher IC50 (72 h) concentration of SCH-527123 than parental cells [HCT116 and E2 (P < 0.005): 28.9 ± 0.02 μmol/L and 39.5 ± 0.01 μmol/L, respectively; Caco2 and IIIe (P < 0.005): 18.8 ± 0.03 μmol/L and 25.5 ± 0.02 μmol/L, respectively]. Therefore, SCH-527123 decreased growth inhibitory activity in colorectal cancer cell lines [2].

The CXCR2 antagonist, SCH-527123, shows antitumor activity and sensitizes cells to oxaliplatin in preclinical colon cancer models.[Pubmed:22391039]
Mol Cancer Ther. 2012 Jun;11(6):1353-64.
Colorectal cancer is the second most common cause of cancer-related death in the United States. Recent studies showed that interleukin-8 (IL-8) and its receptors (CXCR1 and CXCR2) are significantly upregulated in both the tumor and its microenvironment, and act as key regulators of proliferation, angiogenesis, and metastasis. Our previous study showed that IL-8 overexpression in colorectal cancer cells triggers the upregulation of the CXCR2-mediated proliferative pathway. The aim of this study was to investigate whether the CXCR2 antagonist, SCH-527123, inhibits colorectal cancer proliferation and if it can sensitize colorectal cancer cells to oxaliplatin both in vitro and in vivo. SCH-527123 showed concentration-dependent antiproliferative effects in HCT116, Caco2, and their respective IL-8-overexpressing variants colorectal cancer cell lines. Moreover, SCH-527123 was able to suppress CXCR2-mediated signal transduction as shown through decreased phosphorylation of the NF-kappaB/mitogen-activated protein kinase (MAPK)/AKT pathway. These findings corresponded with decreased cell migration and invasion, while increased apoptosis in colorectal cancer cell lines. In vivo results verified that SCH-527123 treatment decreased tumor growth and microvessel density when compared with vehicle-treated tumors. Importantly, these preclinical studies showed that the combination of SCH-527123 and oxaliplatin resulted in a greater decrease in cell proliferation, tumor growth, apoptosis, and angiogenesis that was superior to single-agent treatment. Taken together, these findings suggest that targeting CXCR2 may block tumor proliferation, migration, invasion, and angiogenesis. In addition, CXCR2 blockade may further sensitize colorectal cancer to oxaliplatin treatment.

Structure-activity studies on lead cyclobutenedione 3 led to the discovery of 4 (SCH 527123), a potent, orally bioavailable CXCR2/CXCR1 receptor antagonist with excellent cell-based activity. Compound 4 displayed good oral bioavailability in rat and may be a potential therapeutic agent for the treatment of various inflammatory diseases.
