Napabucasin | STAT3 inhibitor / Cancer cell stemness inhibitor

Napabucasin (83280-65-3) inhibits gene transcription driven by STAT3. Inhibits cancer cell stemness gene expression and blocks spherogenesis of stemness-high cancer cells isolated from a variety of cancer types.¹ Effective antitumor agent as a monotherapy or in combination with other agents such as taxol in mouse models.² Clinical trials have demonstrated encouraging anti-tumor activity with the potential to suppress metastasis and prevent relapse in patients with various types of cancer.^2,3 Overcomes cisplatin resistance in non-small cell lung cancer.⁴
