Uses

Sch 527123 is a potent CXCR2 antagonist. It can potentially inhibits human colon cancer liver metastasis.

General Description

A cell-permeable, orally active, non-toxic, cyclobutenedione compound with anti-inflammatory properties. Acts as a specific, high-affinity, and potent allosteric antagonist of CXCR2 (IC₅₀ = 2.6 nM for human; K_d = 49, 200, and 80 pM for human, rat, and cynomolgus, respectively). Also exhibits high potency against CXCR1 (IC₅₀ = 36 nM for human, K_d = 3.9 and 41 nM for human and cynomolgus, respectively). Displays excellent selectivity over CXCR3, CCR5, and a large panel of GPCRs, enzymes and ion channels (~ 10 μM). Potently inhibits CXCL1- and CXCL8-induced chemotaxis in human neutrophils (hPMN; IC₅₀<1 nM and 16 nM, respectively). Shown to suppress pulmonary neutrophilia (ED₅₀ = 1.3 mg/kg), goblet cell hyperplasia (ED₅₀ = 700 mg/kg), and increase bronchoalveolar lavage (BAL) mucin content (ED₅₀ ≤ 1 mg/kg) in rats subjected to vanadium pentoxide induced pulmonary inflammation. Inhibits melanoma cell proliferation (~ 1 mg/ml) by suppressing the phosphorylation of ERK1/2. Diminishes the invasive potential of melanoma cells and blocks angiogenesis in mice (100 mg/kg, p.o., q.d for 21 days). Exhibits desirable pharmacokinetic properties.

Please note that the molecular weight for this compound is batch-specific due to variable water content.

Biological Activity

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].
