Difelikefalin HCl is a κ-opioid receptor (KOR) agonist. It activates KOR in HEK293 cells expressing the human receptor (EC50 = 0.16 nM in a transactivation assay) and inhibits forskolin-induced cAMP production in R1.G1 mouse thyoma cells (EC50 = 0.048 nM). Difelikefalin HCl is selective for KOR over the μ-opioid receptor (MOR; EC50 = <1 µM in a transactivation assay). It reduces acetic acid-induced writhing, as well as scratching behavior induced by the KOR antagonist GNTI, in mice (ED50s = 0.07 and 0.05 mg/kg, respectively). 在相同实验条件下,摩尔浓度相同的化合物盐形式与游离态具有相同的生物活性,但盐形式 Difelikefalin acetate 的水溶性和稳定性通常比游离态更好。

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。
