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

在6天的时间段内，雄性/大鼠服用豆油中的安得灵，通过粪便排出了66%的剂量...而雌性...则排出了37%。...对粪便的分析显示...安得灵转化为了...抗-12-羟基安得灵...顺-12-羟基安得灵...3-羟基安得灵...12-酮安得灵...以及Δ-酮安得灵...。

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。/

/IN RATS ADMIN ENDRIN, ANALYSIS OF FECES REVEALED/ A POLAR METABOLITE ... TRANS-4,5-DIHYDROISODRIN-4,5-DIOL. ANOTHER POLAR ... NOT IDENTIFIED. ... URINE FROM MALE RATS CONTAINED ENDRIN, 12-KETOENDRIN, ANTI-12-HYDROXYENDRIN & 3-HYDROXYENDRIN (17:19:2:1, RESPECTIVELY).

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：对两种品系的小鼠进行口服毒死蜱处理，在雌雄两性中均未产生致癌作用。国家癌症研究所（NCI）的生物鉴定显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得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；而是D组的分类最能反映这些不确定的数据。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，这是因为恩德林有更快的胆汁排泄。
