An HBL melanoma cell line is established that stably expresses a NF-κB luciferase reporter. In these cells, 0.5 ng/mL TNF-α induces a dose-dependent increase in NF-κB luciferase activity. Treatment of HBL-NF-κB cells with BMS-470539 elicits a dose-dependent, statistically significant reduction in TNF-α-stimulated NF-κB luciferase activity. BMS-470539 has no effect on luciferase reporter activity in the absence of TNF-α stimulation. In nontransfected HBL cells, treatment with BMS-470539 results in a dose-dependent inhibition of NF-B nuclear translocation. has not independently confirmed the accuracy of these methods. They are for reference only.

BMS-470539 (2.05-18.47 mg/kg; intravenous injection; for 125 minutes; WT and MC1 receptor recessive e/e mice) treatment inhibits cell adhesion and emigration with no effect on cell rolling. And also inhibits the tissue expression of both CXCL1 and CCL2. has not independently confirmed the accuracy of these methods. They are for reference only.
