代谢
多溴联苯可以通过口服、吸入和皮肤途径被吸收。一旦进入人体,它们会分布到全身并在血液、母乳和脂肪组织中生物累积。PBDE的代谢程度取决于化的程度。代谢过程被认为涉及脱和甲基化,产生酚类代谢物。代谢和未代谢的PDBE化合物主要通过粪便排出体外。
Polybrominated biphenyls can be absorbed through oral, inhalation, and dermal routes. Once in the body they distribute throughout and bioaccumulate in the blood, breast milk, and adipose tissue. The extent of PBDE metabolism depends on the degree of bromination. Metabolism is believed to involve debromination and methylation, resulting in phenolic metabolites. Metabolized and unmetabolized PDBE compounds are excreted mainly in the faeces. (L628, L881)

  • 毒性总结
像其他卤代芳烃一样,多溴联苯醚会与细胞中的芳烃受体(AhR)结合,该受体调控多种蛋白质的合成。AhR的激活会诱导一系列酶的产生,包括细胞色素P-450依赖的单加氧酶CYP1A和CYP2B家族、UDP-葡萄糖醛酸基转移酶以及乙氧基 resorufin-O-脱乙基酶。PBDEs还被认为是干扰甲状腺激素的产生、传输和处置。其中一种机制涉及PBDEs的代谢物与甲状腺素竞争结合 transthyretin,降低血清甲状腺激素平。甲状腺激素平的变化与甲状腺毒性和神经行为改变有关。某些PBDEs及其代谢物也是内分泌干扰物,可能作为雌激素受体的激动剂或雄激素和孕酮受体的拮抗剂。
Like other halogenated aromatic hydrocarbons, polybrominated diphenyl ethers bind to the cellular aryl hydrocarbon receptor (AhR), which regulates the synthesis of a variety of proteins. Activation of the AhR induces a number of enzymes, including cytochrome P-450-dependent monooxygenases of the CYP1A and CYP2B families, UDP-glucuronosyltransferase, and ethoxyresorufin-o-deethylase. PBDEs are also believed to disrupt the production, transport, and disposition of thyroid hormones. One mechanism of this involves metabolites ot PDBEs competing with thyroxine to bind to transthyretin, decreasing serum thyroid hormone levels. This change in thyroid hormone levels has been linked to both thyroid toxicity and neurobehavioral alterations. Certain PDBEs and their metabolites are also endocrine disruptors and may act as agonists at the estrogen receptors or antagonists at the androgen and progesterone receptors. (L628, A262)
