General description

A cell-permeable, bioactive, non-toxic naphthofurandione analog that blocks STAT3-driven gene transcription. Selectively diminishes gene expression and self-renewal in stemness high cancer cells. Shown to be more effective in stemness high cancer cell population (IC50 = 142 nM) compared to regular cancer cells (IC50 = 395 nM). Reduces spherogenesis in CD44 expressing cancer cells without affecting the colony formation in CD34+ hematopoietic stem cells. Effectively reduces the levels of Nanog, Axl, Sox-2, Klf4, survivin, c-Myc, Bmi-1, and β-catenin within a few hours following treatment. Displays broad spectrum activity against stemness high cancer cells from multiple tumors (IC50 = 291, 432, 624, 479, 549, and 729 nM for CAOV-3, SW-626, PaCa2, SNU-475, H1975, and U87-MG, respectively). Suppresses the growth of PaCa-2 xenografts in murine models that exhibited relapse of tumor growth (20 mg/kg, i.p, q.d.) following the cessation of 41-day gemcitabine treatment. Also shown to block cancer relapse, and spleen and liver metastasis in the intrasplenic nude mouse model injected with HT29 colon cancer cells.
