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].
