代谢
四只 Sprague-Dawley 大鼠/性别通过口服灌胃接受单一剂量的50 mg/kg的混合物,包括Methylene-14C FMC 57020(比活性:26.85 mCi/mmol,放射性化学纯度:99.3%)和Carbonyl-14C FMC 57020(比活性:27.98 mCi/mmol,放射性化学纯度:99.3%)。从尿液和粪便样本中回收放射性标记化合物并进行分析...以识别测试材料的各种代谢物。回收并鉴定了12种代谢物。苯基和/或异恶唑啉酮环的羟基化是母体化合物最常见的改变,观察到一些葡萄糖醛酸和硫酸结合的证据。
Four Sprague-Dawley rats/sex were treated by oral gavage with a single dose of 50 mg/kg of a mixture of Methylene-14C FMC 57020 (specific activity: 26.85 mCi/mmol, radiochemical purity: 99.3%) and Carbonyl-14C FMC 57020 (specific activity: 27.98 mCi/mmol, radiochemical purity: 99.3%). Radiolabeled compounds were recovered from the urine and feces samples and analyzed... in order to identify various metabolites of the test material. Twelve metabolites were recovered and identified. Hydroxylation of the phenyl and/or isoxazolidinone rings was the most common alteration of the parent compound which was observed with some evidence of glucuronide and sulfate conjugation.
