Abstract:

本研究开发了一种简单可靠的HPLC-UV方法用于美氟尼酮的测定生物分析步骤包括500 μL肝微粒体系统中通过甲醇沉淀蛋白质提取美氟尼酮。色谱条件:色谱柱为Agilent TC-C18(4.6 mm×250 mm, 5 μm), 流动相为10 mM甲酸铵(10%的甲酸调PH2.9)–乙腈(70:30, v/v),流速为1.0 mL/min, UV检测波长设定在245 nm美氟尼酮和吡非尼酮(内标)分别在6.09.7分钟洗脱,总运行时间为12分钟根据美国食品和药物管理局生物分析指南,进行了方法验证,结果符合验收标准。美氟尼酮在肝微粒体中的标准曲线在0.5–16 μg/mL范围内呈线性关系。美氟酮内和外间精确度低于9.0,偏差在±10.0%以内。美氟尼酮在肝微粒体中孵育后,该方法成功应用于药代动力学研究。
