代谢
zeranol 在肝脏中发生代谢。在 I 期代谢过程中,脱氢反应产生 zearalanone 作为主要代谢物和 beta-zearalanol 作为次要代谢物。细胞色素 P450 酶还催化 zeranol 的芳香羟基化,产生 13-羟基-α-zearalanol 和 15-羟基-α-zearalanol。在 II 期代谢过程中发生还原/氧化反应,形成 zearalanone 和 beta-zearalanol 的葡萄糖苷酸和硫酸盐结合物。在人体内,代谢物主要通过尿液排出。(A2966)
Metabolism of zeranol occurs in the liver. During phase I metabolism, dehydrogenation produces zearalanone as the major metabolite and beta-zearalanol as the minor metabolite. Cytochrome P450 enzymes also catalyze the aromatic hydroxylation of zeranol, producing 13-hydroxy-alpha-zearalanol and 15-hydroxy-alpha-zearalanol. During phase II metabolism reduction/oxidation occurs, forming the glucuronide and sulfate conjugates of zearalanone and beta-zearalanol. In humans, the metabolites are excreted mainly in the urine.
