  Synthesis of Polybrominated Diphenyl Ethers and Their Capacity to Induce CYP1A by the Ah Receptor Mediated Pathway

  摘要：

  Polybrominated diphenyl ethers (PBDEs) have become widely distributed as environmental contaminants due to their use as flame retardants. Their structural similarity to other halogenated aromatic pollutants has led to speculation that they might share toxicological properties such as hepatic enzyme induction. In this work we synthesized a number of PBDE congeners, studied their affinity for rat hepatic Ah receptor through competitive binding assays, and determined their ability to induce hepatic cytochrome P-450 enzymes by means of EROD (ethoxyresorufin-O-deethylase) assays in human, rat, chick, and rainbow trout cells. Both pure PBDE congeners and commercial PBDE mixtures had Ah receptor binding affinities 10(-2)-10(-5) times that of 2,3,7,8-tetrachlorodibenzo-p-dioxin. In contrast with polychlorinated biphenyls, Ah receptor binding affinities of PBDEs could not be related to the planarity of the molecule, possibly because the large size of the bromine atoms expands the Ah receptor's binding site. EROD activities of the PBDE congeners followed a similar rank order in all cells. Some congeners, notably PBDE 85, did not follow the usual trend in which strength of Ah receptor binding affinity paralleled P-450 induction potency. Use of the gel retardation assay with a synthetic oligonucleotide indicated that in these cases the liganded Ah receptor failed to bind to the DNA recognition Sequence.

  Hydroxylated and methoxylated polybrominated diphenyl ethers (OH-PBDEs and MeO-PBDEs) may be natural products or they may be formed as metabolites of polybrominated diphenyl ethers (PBDEs), frequently used as flame retardants. The aim of this work was to synthesize authentic OH- and MeO-PBDE reference standards for analytical and toxicological studies. Brominated phenoxybenzaldehydes were prepared

  羟基化和甲氧基化的多溴联苯醚（OH-PBDEs 和 MeO-PBDEs）可能是天然产物，也可能作为多溴化二苯醚 (PBDEs) 的代谢物形成，通常用作阻燃剂。这项工作的目的是为分析和毒理学研究合成真正的 OH- 和 MeO-PBDE 参考标准。溴化苯氧基苯甲醛通过 2,4-二溴苯酚与各种氟苯甲醛的偶联或通过溴化羟基苯甲醛与 2,2',4,4'-四溴二苯基氯化碘的偶联制备。OH-PBDEs 是通过 Baeyer-Villiger 氧化和酸催化水解通过溴化苯氧基苯甲醛合成的。这些 OH-PBDEs 用三溴化苄基三甲基铵进行邻溴化和对溴化（相对于羟基）和/或用溴/叔丁胺邻溴化，并且在一种情况下也用溴溴化。MeO-PBDEs 是通过甲基化制备的 OH-PBDEs 获得的。MeO-PBDEs 也通过溴化甲氧基苯酚与 2,2',4,4'-四溴二苯基碘盐偶联制备，脱甲基后得到相应的 OH-PBDEs。大多数制备的

The most abundant compound originated from the natural tetrabromo phenoxyanisole BC-3 which may have a 3:1 distribution of bromine on the two phenyl units. This sample also accumulated a dibromochloroanisole, as well as a
