代谢
在给予 Sprague-Dawley 大鼠(n = 5)单次剂量为 150 mg/kg 的 2,3-苯并呋喃后,研究了其代谢物在尿液中的排泄。在给药后长达 7 天的时间内,按定义的时间间隔收集尿液样本,并使用 (1) H NMR 和直接耦合高效液相色谱(HPLC)-NMR、HPLC-(质谱) MS 和 HPLC-MS-NMR 方法进行分析。主要代谢物被确定为 2-羟基苯乙酸和 2-(2-羟基乙基)苯基氢硫酸盐,分别占剂量的 24.3 +/- 6.0% 和 19.6 +/- 6.4%。
The urinary excretion of metabolites of 2,3-benzofuran was studied in Sprague-Dawley rats (n = 5) given a single dose of 150 mg/kg i.p. Urine samples were collected at defined intervals up to 7 days postdose and analyzed using (1). H NMR and directly coupled high performance liquid chromatography (HPLC)-NMR, HPLC-(mass spectrometry) MS and HPLC-MS-NMR methods. The principal metabolites were determined to be 2-hydroxyphenylacetic acid and 2-(2-hydroxyethyl)phenyl hydrogen sulfate, representing 24.3 +/- 6.0% and 19.6 +/- 6.4% of the dose, respectively.
