Napabucasin (BBI608) is a potent and selective STAT3 inhibitor. Napabucasin can inhibit gene transcription driven by Stat3 and cancer stemness properties, can inhibit stemness gene expression and block spherogenesis of or kill stemness-high cancer cells isolated from a variety of cancer types (IC50 ~0.14-1.25 µM), but not hematopoietic stem cells. Napabucasin inhibits PaCa-2 xenograft tumor growth in mice, even after cessation of treatment, and decreases population of CSCs in PaCa-2 tumors from treated mice.
