产品描述 | STF-118804 is a highly specific NAMPT inhibitor; reduces the viability of most B-ALL cell lines with IC50 <10 nM. |
靶点活性 | B-ALL cells:<10 nM. |
体外活性 | STF-118804 reduces the viability of B-ALL cell lines containing MLL chromosomal translations, with IC50 values in the low nanomolar range. In addition, leukemic samples from ?ve pediatric ALL patients are also sensitive to STF-118804 in the low nanomolar range. STF-118804 induces leukemia MV411 cell apoptosis without antecedent cell cycle arrest. [1] |
体内活性 | STF-118804 (25 mg/kg twice daily, s.c.) improves survival in an orthotopic xenotransplant model of high-risk acute lymphoblastic leukemia, and effectively depletes leukemia-initiating cells. [1] |
激酶实验 | Enzyme Assays: The enzymatic activities of NAMPT and NMNAT are measured using in vitro kits and using the Two-Step Method per manufacturer's instructions. Compounds, NAMPT and/or NMNAT enzymes, and their substrates are mixed and incubated at 30°C for 1 hour. Reagents for the indicator reaction (Wst-1) are then added, and absorbance is read at 450 nm every 5 min at 30°C on a Tecan In?nite M100 multimode plate reader. |
细胞实验 | Human cell lines or lineage negative cord blood cells were seeded into 96-well plates (6×105 cells per milliliter). Compounds are added in increasing concentrations, and cells are incubated at 37°C/5% CO2 for 72 hours. To detect viability, CellTiter-Blue reagent is added at 1:10 dilution, and plates are incubated for 4 hours at 37°C/5% CO2 prior to reading on a Flexstation II 384 or a Synergy H1 reader at an excitation of 555 nm and emission detection of 590 nm. Cell viability is also measured by CellTiter-Fluor. The cell-permeable ?uorogenic peptide substrate GF-AFC reagent is added at 1:2 dilution, and plates are incubated for 30 min at 37°C/5% CO2 prior to reading on a Synergy H1 reader at an excitation of 380 nm and emission detection of 505 nm. Cord blood cells are enumerated on a hemocytometer, and cell viability is assessed with trypan blue exclusion dye. Inhibitory concentration (IC50) is calculated using Prism software. Primary patient samples are plated in 96-well plates and treated with increasing concentrations of STF-118804 for 48 hours at 37°C in 5% CO2. WST-1 reagent is added to the culture medium (1:10 dilution), and absorbance is measured at 450 nm using a Bio-Rad model 680 microplate reader. All assays are performed in triplicate. IC50 is calculated using CalcuSyn version 2.0 software.(Only for Reference) |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
