代谢
调查人员给雌性Wistar白化大鼠(每组3只)口服50毫克/千克[14C]-二氯酚,溶解在丙烷-1,2-二醇中... 识别出以下尿液代谢物:4%二氯酚;17%二氯酚硫酸盐;25%二氯酚单葡萄糖醛酸苷;以及19%二氯酚双葡萄糖醛酸苷。胆管插管的 rats 在给药后1到4小时内排泄了36%剂量的[14C]-二氯酚。肠道内容和肠壁分别含有32%和11%的[14C]-二氯酚,而2%在尿液中发现。仅在胆汁中发现了[14C]-二氯酚的单葡萄糖醛酸苷代谢物。调查人员认为二氯酚经历了肠肝循环。
/Investigators/ dosed female Wistar albino rats (3/group) orally with 50 mg/kg [14C]-dichlorophene dissolved in propane-1,2-diol. ... The following urinary metabolites were identified: 4% dichlorophene; 17% dichlorophene sulfate; 25% dichlorophene monoglucuronide; and 19% dichlorophene diglucuronide. Bile duct-cannulated rats excreted 36% of the dose of [14C]-dichlorophene 1 to 4 hr after dosing. The intestinal contents and the intestinal wall had 32% and 11% [14C]-dichlorophene, respectively, whereas 2% was found in the urine. Only the monoglucuronide metabolite of [14C]-dichlorophene was found in the bile. The investigators suggested that dichlorophene underwent enterohepatic circulation.
