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。

 95.000mg/ml (200.65mM) Taking the 1 mL working solution as an example, add 95 mg of this product to 1 ml of ddH2O, mix evenly to make it clear, 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 Rigosertib (ON-01910) is a non-ATP-competitive inhibitor of PLK1 with IC50 of 9 nM in a cell-free assay. It shows 30-fold greater selectivity against Plk2 and no activity to Plk3. Rigosertib inhibits PI3K/Akt pathway and activates oxidative stress signals. Rigosertib induces apoptosis in various cancer cells. Phase 3.
in vitro Rigosertib (ON-01910) is a non-ATP-competitive inhibitor to PLK1 with IC50 of 9 nM. It also exhibits inhibition against PLK2, PDGFR, Flt1, BCR-ABL, Fyn, Src, and CDK1, with IC50 of 18-260 nM. This compound shows cell killing activity against 94 different tumor cell lines with IC50 of 50-250 nM, including BT27, MCF-7, DU145, PC3, U87, A549, H187, RF1, HCT15, SW480, and KB cells. While in normal cells, such as HFL, PrEC, HMEC, and HUVEC, it has little or no effect unless its concentration is greater than 5-10 μM. In HeLa cells, Rigosertib (100-250 nM) induces spindle abnormalities and apoptosis. [1] It also inhibits several multidrug resistant tumor cell lines, including MES-SA, MES-SA/DX5a, CEM, and CEM/C2a, with IC50 of 50-100 nM. In DU145 cells, this compound (0.25-5 μM) blocks cell cycle progression in G2/M phase, results in an accumulation of cells containing subG1 content of DNA, and activates apoptotic pathways. In A549 cells, it (50 nM-0.5 μM) induces loss of viability and caspase 3/7 activation. [2] In a recent study, Rigosertib induces apoptosis in chronic lymphocytic leukemia (CLL) cells without toxicity against T-cells or normal B-cells. It also abrogates the pro-survival effect of follicular dendritic cells on CLL cells and reduces SDF-1-induced migration of leukemic cells. [3]
in vivo In mouse xenograft models of Bel-7402, MCF-7, and MIA-PaCa cells, Rigosertib (ON-01910) (250 mg/kg) markedly inhibits tumor growth. [1] This compound (200 mg/kg) also shows inhibition on tumor growth in a mouse xenograft model of BT20 cells. [2]

キナーゼアッセイ In vitro enzyme assays for PLK1
Recombinant PLK1 (10 ng) is incubated with different concentrations of Rigosertib (ON-01910) in a 15 µL reaction mixture (50 mM HEPES, 10 mM MgCl2, 1 mM EDTA, 2 mM Dithiothreitol, 0.01% NP-40 [pH 7.5]) for 30 min at room temperature. Kinase reactions are performed for 20 min at 30 °C in a volume of 20 µL (15 µL enzyme + this compound, 2 µL 1 mM ATP), 2 µL of γ32P-ATP (40 μCi), and 1 µL of recombinant Cdc25C (100 ng) or casein (1 μg) substrates. Reactions are terminated by boiling for 2 min in 20 µL of 2× Laemmli buffer. Phosphorylated substrates are separated by 18% SDS-PAGE. The gels are dried and exposed to X-ray film for 3-10 min.

濃度 1 nM - 10 μM, dissolved in DMSO as stock solution.
反応時間 96 hours
実験の流れ Cells are grown in either DMEM or RPMI supplemented with 10% fetal bovine serum and 1 unit/mL penicillin-streptomycin solution. Tumor cells are plated into six-well dishes at a density of 1 × 105cells/mL/well, and Rigosertib (ON-01910) is added 24 hours later at various concentrations. Cell counts are determined from duplicate wells after 96-hour of treatment with this compound. The total number of viable cells is determined by trypan blue exclusion.
動物実験 動物モデル Mouse (female athymic, NCR-nu/nu) xenograft models of Bel-7402, MCF-7, and MIA-PaCa cells
