sequential reactions to give PGH2 as a final product. Here, we report the synthesis of a new PGHS model, which has two binaphthol bridges in one side of an iron porphyrin. Its substrate reaction site is more flexible and accordingly less hindered than the previous four binaphthol-bridged twin-coronet-type models (FeTCP). The present model is expected to accept higher olefins, which can reach the intermediate
前列腺素H合酶(PGHSs)是含血红素的酶,其直接添加两个O 2由1,4-二烯部分的H-原子抽象的开始和通过连续反应分子成花生四烯酸(AA),得到PGH 2作为完成品。在这里,我们报告了一种新的PGHS模型的合成,该模型在铁卟啉的一侧具有两个联萘酚桥。它的底物反应位点比之前的四个联萘酚桥联的双皇冠型模型(FeTCP)更灵活,因此受阻也更少。期望本模型接受高级烯烃,该高级烯烃可以到达该配合物中的中间苯氧基自由基和铁。处理后的铁络合物与米CPBA在−50°C下成功地定量生成了相应的萘氧基自由基,其特征是萘氧基自由基在385和485 nm处的特征吸收度增加,并且其ESR信号增强,并通过加入N,N-二甲基苯胺作为有效的还原剂。
