Napabucasin (BBI608) is an orally availableStat3and cancer cell stemness inhibitor. In vitro
Napabucasin downregulates stemness gene expression driven by Stat3 and cancer stemness properties, and effectively inhibits self-renewal of stemness-high cancer cells with IC50 ranged from 0.291~1.19 μM, on inhibition on normal stem cells.
In vivo
In mice bearing PaCa-2 xenografts, Napabucasin (20 mg/kg, i.p.) significantly inhibits tumor growth, relapse and metastasis. Cell Data
