measurement of mitolactol levels in plasma. The basis of the assay is the reaction at pH 7.4 and 50 degrees C of mitolactol with diethyldithiocarbamate to form 1,6-bis(diethyldithiocarbamoyl)-2,3,4,5-tetrahydroxyhexane. This derivative is then extracted into chloroform, resolved by normal-phase chromatography, and detected by UV (254 nm) absorbance. The method quantitates the sum of mitolactol and its active
描述了一种涉及柱前衍生化和高效液相色谱的方法,用于测量血浆中的蜜三醇水平。该测定法的基础是米托内醇在pH 7.4和50摄氏度下与二乙基二硫代氨基甲酸酯反应形成1,6-双(二乙基二硫代氨基甲酰基)-2,3,4,5-四羟基己烷。然后将该衍生物萃取到氯仿中,通过正相色谱法分离,并通过UV(254 nm)吸光度进行检测。该方法定量测定血浆中低至0.5 microM浓度的美托内醇及其活性双功能代谢产物溴代环氧二乙醇和双脱水半乳糖的总和。腹膜内注射20或100 mg / kg体重后,已经确定了该药物在小鼠中的药代动力学参数。到5分钟,从腹膜腔的吸收基本完成。获得的参数包括一阶消除常数k = 0.92 X 10(-2)min-1和表观分布体积Vd = 0.78 L / kg。对于100 mg / kg剂量,浓度-时间曲线下的面积为49 mM X min,腹膜内注射后40 min达到平均峰值药物浓度。总血
