产品描述 | GeA-69 (GeA69) is a selective and allosteric PARP14 macrodomain 2 (MD2) inhibitor (Kd: 0.86 μM in ITC assays). |
靶点活性 | PARP14:0.86 μM (Kd, in ITC assays) |
体外活性 | The macrodomain recruitment was significantly decreased in cells pre-treated with 50 μM GeA-69 and completely prevented in cells exposed to 250 μM GeA-69. |
激酶实验 | Binding experiments were carried out on a VP-ITC microcalorimeter. All experiments were performed in 50 mM HEPES (pH 7.4), 300 mM NaCl, 5 % glycerol, 0.5 mM TCEP at 12 °C, a reference power of 12 μCal/sec and a stirring speed of 307 rpm. The titrations were conducted using an initial injection of 2 μL followed by 28 identical injections of 10 μL with duration of 4 sec (per injection) and a spacing of 240 sec between injections. Competition experiments were performed on an iTC200 instrument at 20 °C, a reference power of 12 μCal/sec and a stirring speed of 1000 rpm. Following an initial injection of 0.2 μL, 20 identical injections of 2 μL were run with a duration of 4 sec (per injection) and a spacing of 150 sec between injections. Data analysis was carried out using Origin software with the MicroCal plugin. Thermodynamic parameters were calculated using ΔG = ΔH ? TΔS = ?RTlnKB, where ΔG, ΔH, and ΔS are the changes in free energy, enthalpy, and entropy of binding, respectively. In all cases, a single binding site model was employed. |

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。
