产品描述 | Omecamtiv mecarbil (CK-1827452) has been used in trials studying the treatment and basic science of Heart Failure, Echocardiogram, Pharmacokinetics, Chronic Heart Failure, and History of Chronic Heart Failure, among others. |
体外活性 | Omecamtiv mecarbil会导致一些血流动力学参数(包括心率,平均左心房压力和左心室舒张末期压力)的下降.OOmecamtiv mecarbil在左心室肥大的清醒的狗体内,对血流动力学参数产生相似且无统计学差异的影响.在有心肌梗死(MI-sHF)的有意识的狗中,Omecamtiv mecarbil导致壁增厚(25%),每搏输出量(44%),心输出量(22%)和左心室(LV)收缩射血时间显著增加(26%). |
体内活性 | 在离体心肌细胞中,Omecamtiv mecarbil可以增加肌细胞收缩力,克服肌球蛋白抑制剂BDM而不增加钙瞬变或抑制PDE通路。在体外,Omecamtiv mecarbil通过增加肌球蛋白ATPase速率选择性地激活心肌肌球蛋白。 |
激酶实验 | Axl Kinase activity assay: Test compounds are diluted to desired concentrations in kinase reaction buffer (50 mM HEPES pH 7.5, 10 mM MgCl2, 1 mM EGTA, 2 mM DTT, and 0.01% v/v Tween-20) and are briefly incubated with Axl kinase. The Axl kinase used is recombinant human Axl kinase (catalytic domain, amino acids 473-894) with a histidine tag. The reaction is initiated by the addition of ATP and fluorescein-labeled poly-GT substrate (poly Glu:Tyr, 4:1 polymer). Concentration of the various components in the assay (10 μL reaction volume) are: 1% DMSO, 93 ng/mL Axl kinase, 20 μM ATP, and 200 nM fluorescein poly-GT substrate. Following addition of ATP and fluorescein poly-GT substrate, incubation is for 60 min at room temperature, the enzyme reaction is stopped by addition of 10 μL terbium-labeled anti-phosphotyrosine PY20 antibody in EDTA-containing buffer. Final concentration of EDTA and antibody after addition to the reaction is 10 mM and 2 nM, respectively. The terbium conjugated antibody generates a time-resolved FRET signal with the fluorescein molecule (bound to the poly-GT substrate) when the substrate is phosphorylated. After one hour incubation at room temperature, fluorescence is measured with excitation of 320 nm and dual emission of 495 and 520 nm on an EnVision microplate reader. Signal is expressed in -636996terms of a TR-FRET ratio (fluorescence intensity at 520 nm to 495 nm). |

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。
