代谢
雄性大鼠通过口服、气管内和静脉注射途径分别给予5、50或500毫克/千克的(14)C-乙二胺(EDA)。6到9%的管理放射性通过呼出的空气以(14)CO2的形式排出。主要代谢物n-乙酰乙二胺约占尿液放射性的半数。根据剂量水平的不同,2-49%的放射性保持为未改变的母体化合物。给药途径似乎并未改变代谢轮廓。
Male rats were dosed with (14)C-ethylenediamine (EDA) at 5, 50, or 500 mg/kg by oral, endotracheal, and iv routes. Six to 9% of the admin radioactivity was eliminated via expired air in the form of (14)CO2. n-Acetylethylenediamine, a major metabolite, accounted for approx half of the urinary radioactivity. Depending on the dosage level, 2-49% of the radioactivity was unchanged parent cmpd. The route of admin did not appear to change the metabolic profile.
