产品描述 KRIBB11 is an inhibitor of Heat shock factor (HSF) inhibitor.
靶点活性 HSF1:1.2 μM
体外活性 KRIBB11 inhibits HSF1 activity in a concentration-dependent manner. It down-regulates HSP70 and HSP27. KRIBB11 can inhibit cancer cell proliferation, arrests the cell cycle at G2/M phase and induces apoptosis. But it does not inhibit heat shock-induced recruitment of HSF1 to the hsp70 promoter or phosphorylation of HSF1 Ser-230. KRIBB11 inhibits heat shock-induced recruitment of pTEFb to the hsp70 promoter and p-TEFb-dependent Phosphorylation of polⅡ CTD Ser-2[1].
体内活性 Using a mouse xenograft model, KRIBB11 treatment decreases tumor volume by 47% compared with untreated control mice. In addition, HSP70 protein levels are significantly decreased in tumors from mice treated with KRIBB11, supporting the notion that KRIBB11 exerts its in vivo antitumor activity through HSF1 inhibition[1].
激酶实验 HCT-116 cells are washed with PBS and then homogenized with a 27-gauge syringe in binding buffer (10 mm Tris-HCl (pH 7.4), 50 mm KCl, 5 mm MgCl2, 1 mm EDTA, and 0.1 mm Na3VO4). The cell lysate is centrifuged at 13,000 rpm for 30 min at 4°C, and the supernatant is collected. The HCT-116 cell lysate supernatant is precleared by incubating with Dynabeads M-280 streptavidin for 30 min at 4°C and captured by magnet separation. The cleared supernatants are incubated with biotinyl-KRIBB11 compound. After overnight incubation at 4°C, proteins associated with the biotinyl-KRIBB11 compound are precipitated with Dynabeads M-280 streptavidin. Precipitated samples are separated by a magnet. Samples are washed with 1 mL of ishing buffer containing 50 mm HEPES (pH 7.5), 50 mm NaCl, 1 mm EDTA, 1 mm EGTA, 0.1% Tween 20, 10% (v/v) glycerol, 1 mm NaF, 0.1 mm Na3VO4, and protease inhibitor mixture tablets (1 tablet/10 mL). Samples are boiled in SDS-PAGE sample buffer, separated by 10% polyacrylamide gel, and immunoblotted with antibodies against HSF1, HSF2, HSP90, or CDK9.
细胞实验 HCT-116 cells are treated with KRIBB11 at various concentrations for 48 h. Cells are then harvested by trypsinization, fixed with 70% chilled ethanol, and preserved at ?20 °C before FACS analysis. Fixed cells are washed twice with phosphate-buffered saline (PBS) solution before being suspended in 500 μl of PBS and treated with 100 mg/ml RNase A at 37 °C for 30 min. Propidium iodide is then added to a final concentration of 50 mg/ml for DNA staining, and 20,000 fixed cells are analyzed on a FACSCalibur system. Cell cycle distribution is analyzed using the ModFit program.(Only for Reference)

TargetMol Calculator 体内实验配液计算器

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。

第一步:请输入动物实验的基本信息
