この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。

0.250mg/ml (1.04mM) Taking the 1 mL working solution as an example, add 100 μL of 2.5 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 450 μL of ddH2O to make it clear. Volume up to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 Napabucasin (BBI608)は、経口投与可能なStat3およびがん細胞幹細胞性阻害剤です。
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.

実験の流れ

For cancer stem cells, spheres are dissociated and plated under cancer stem cell culture conditions on coated 96-well plates. After 72 h of culture, wells are dosed with the indicated compounds. Seventy-two hours or 24 h after dosing, CellTiter-Glo 2.0 is added to each well, and the luminescence is measured as described by the manufacturer. IC50 values are calculated by fitting a four parameter dose–response curve to normalized data using GraphPad Prism software. For bulk cells, cells are plated at 5,000 cells per well on 96-well plates. Twenty-four hours after plating, cells are treated with the indicated compounds. Viability is determined at 72 h as described above.
