产品描述 | Polyoxyethylene stearate (POES) is an agent of non-ionic emulsifying. |
体外活性 | Polyoxyethylene stearate inhibits P-gp mediated efflux in a concentration-dependent manner mainly by modulating substrate-stimulated P-gp ATPase activity. Polyoxyethylene stearate has been recommended as an additive to the radiolabelled 7H12 Middlebrook TB media and as such has been shown to enhance the growth of mycobacteria in the radiometric BACTEC rapid culture system. tuberculosis and polyoxyethylene (30) stearate and polyoxyethylene (JL) stearate for species of mycobacteria other than M. tuberculosis. Polyoxyethylene 40 stearate reduces vinblastine sulfate efllux. The cytotoxicity of vinblastine to K562/ADR cells is significantly enhanced when the cells are cotreated with 100 or 150 μg/mL polyoxyethylene 40 stearates. Polyoxyethylene (50) stearate produces the greatest enhancement in growth and reduction in the time taken to detect growth for M [1][2][3]. |
体内活性 | The average tumor volume and average tumor weight are significantly less in the polyoxyethylene 40 stearate+vinblastine group. The inhibition rate for tumor growth is increased from 0.06 (vinblastine group) to 0.84 (vinblastine+polyoxyethylene 40 stearate group). Polyoxyethylene stearate is potentially useful as a pharmaceutical ingredient to improve the oral bioavailability of coadministered P-gp substrates and substrates for certain CYP isoforms [2][3]. |

对于不同动物的给药剂量换算,您也可以参考 更多...
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。
