代谢
对大鼠进行了一次(低剂量和高剂量)和多次(低剂量)放射性标记的溴乙酰胺的代谢研究。溴乙酰胺能够从胃肠道被轻易吸收,广泛代谢(主要通过在6-甲基位置和次丁基部分进行羟基化),并且迅速排泄。羟基代谢物以葡萄糖苷酸结合物的形式被排出。在大鼠尿液中,溴乙酰胺的主要代谢物是5-溴-6-羟甲基-3-次丁基脲嘧啶。尿液中还排出了微量的母化合物和另外两种(未确定)的代谢物。
Metabolic studies were conducted with rats given single (low and high) and multiple (low) doses of radiolabelled bromacil. ... Bromacil was absorbed readily from the gastrointestinal tract, extensively metabolized (primarily by hydroxylation at the 6-methyl position and on the sec-butyl moiety), and rapidly excreted. The hydroxylated metabolites were eliminated as glucuronide conjugates. ... The major metabolite of bromacil in the urine of rats was 5-bromo-6-hydroxymethyl-3-sec-butyluracil. Trace levels of the parent compound and two other (unidentified) metabolites were excreted in the urine.
