代谢

在动物体内，恩德林被降解，主要是转化为9-酮恩德林和9-羟基恩德林，但也转化为5-羟基恩德林。

IN ANIMALS, ENDRIN IS DEGRADED, LARGELY TO 9-KETOENDRIN & 9-HYDROXYENDRIN, BUT ALSO TO 5-HYDROXYENDRIN.

代谢

代谢

在大鼠中给予恩德林后，对粪便的分析揭示了一种极性代谢物...反式-4,5-二氢异恩德林-4,5-二醇。另一种极性代谢物尚未被鉴定出来。...雄性大鼠的尿液中包含了恩德林、12-酮恩德林、反-12-羟基恩德林和3-羟基恩德林（比例分别为17:19:2:1）。雌性大鼠的提取物中不包含12-酮恩德林。/建议：12-酮恩德林是最有毒的。/

代谢

在兔体内，(14)C-狄氏剂代谢为反式-12-羟基狄氏剂，到较小于程度的顺式-12-羟基狄氏剂。羟基代谢物主要以硫酸盐结合物形式排出，但也会以葡萄糖醛酸结合物形式排出。

In the rabbit (14)C endrin is metabolized to anti-12-hydroxy endrin and to a lesser extent syn-12-hydroxyendrin. The hydroxylated metabolites are excreted mainly as sulfate conjugates but also as glucuronide conjugates.

毒理性

• 致癌性证据

分类：D；无法归类为人类致癌性。分类依据：内吸磷的口服给药在两种品系的小鼠的任一性别中均未产生致癌作用。国家癌症研究所（NCI）的生物鉴定提示雄性和雌性大鼠有反应，尽管NCI报告了无证据结论。几个生物鉴定的不充分性使报告的阴性结果的可信度受到质疑。这些不充分性和NCI生物鉴定中的提示性反应不支持E组的分类；相反，D组的分类最能反映这些模棱两可的数据。人类致癌性数据：不充分。动物致癌性数据：不充分。

CLASSIFICATION: D; not classifiable as to human carcinogenicity. BASIS FOR CLASSIFICATION: Oral administration of endrin did not produce carcinogenic effects in either sex of two strains of mice. An NCI bioassay was suggestive of responses in male and female rats although NCI reported a no evidence conclusion. The inadequacies of the several bioassays call into question the strength of the reported negative findings. These inadequacies and the suggestive responses in the NCI bioassay do not support a Group E classification; rather a Group D classification best reflects the equivocal data. HUMAN CARCINOGENICITY DATA: Inadequate. ANIMAL CARCINOGENICITY DATA: Inadequate.

吸收、分配和排泄

恩德林从血浆中清除的速度比狄尔德林快得多，因为胆汁排泄更快。
