≥5mg/ml Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
* <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 Importazole is a small molecule inhibitor of the transport receptor importin-β (Karyopherin beta) specifically blocking importin-β-mediated nuclear import. Importazole induces apoptosis and inhibits tumor growth.
in vitro Importazole is an effective inhibitor of the Ran/importin-β interaction in vitro. This compound specifically blocks importin-β-mediated nuclear import both in Xenopus egg extracts and cultured cells, without disrupting transportin-mediated nuclear import or CRM1-mediated nuclear export. When added during mitosis, this chemical impairs the release of an importin-β cargo FRET probe and causes both predicted and novel defects in spindle assembly[1]. It also inhibits proliferation and induces apoptosis of multiple myeloma cells by blocking the NF-κB signal pathway in vitro[2].

細胞アッセイ 細胞株 HEK 293 cells
濃度 40 μM
反応時間 1 h
実験の流れ For all import and export experiments, HEK 293 cells stably expressing NFAT-GFP are grown on glass coverslips to approximately 50% confluency prior to drug treatment. In all cases, importazole is used at 40 μM and leptomycin B is used at 10 ng/ml. For controls, DMSO is used at a concentration of 0.4%. Ionomycin is added at 1.25 μM. This compound and leptomycin B treatments are all for 1 hour. In all experiments cells are fixed with 4% formaldehyde prior to fluorescence microscopy. DNA is visualized with 1 μg/ml Hoechst dye. For quantification, 100 cells from each condition are analyzed and the percentage that shows nuclear accumulation of NFAT-GFP calculated.
