  心磷脂氧化形成 4-羟基壬烯醛：分子内过氧自由基加成和分解。

  摘要：

  我们在此报告细胞色素 c 和 H(2)O(2) 氧化线粒体特异性磷脂四亚油酰心磷脂 (L(4)CL) 导致 4-羟基-2-壬烯醛 (4-HNE) 的形成一种涉及跨链过氧自由基加成和分解的新化学机制。作为最具生物活性的脂质亲电试剂之一，4-HNE 具有多种生物活性，从调节多种信号转导途径到诱导内在细胞凋亡。然而，人们对 4-HNE 在体内的形成位置和方式知之甚少。最近提出了一种新的化学机制，涉及脂肪酸通过过氧键形成的分子间二聚化；但这种机制的生物学相关性尚不清楚，因为大多数脂肪酸在细胞膜的磷脂中被酯化。我们假设心磷脂的氧化，尤其是 L(4)CL，可能会通过这种新机制导致 4-HNE 的形成。我们采用 L(4)CL 和二亚油酰磷脂酰胆碱 (DLPC) 作为模型化合物来测试这一假设。事实上，在旨在评估分子内机制的实验中，与 1-palmitoyl-2-linoleoylphosphatydylcholine

  alpha-Tocopherol was reacted with 1-palmitoyl-2-[(9Z,11E)-(S)-13-hydroperoxy-9,11-octadecadienoyl]-3-sn-phosphatidylcholine (13-PLPC-OOH) in the presence of a lipid-soluble iron chelate, Fe(III) acetylacetonate, in methanol at 37 degreesC. The reaction product was isolated and identified as a mixture of 1-palmitoyl-2-[(10E)-(12S,13S)-9-(8a-dioxy-alpha-tocopherone)-12,13-epoxy-10-octadecenoyl]-3-sn-phosphatidylcholine and 1-palmitoyl-2-[(9Z)-(12S,13S)-11-(8a-dioxy-alpha-tocopherone)-12,13-epoxy-9-octadecenoyl]-3-sn-phosphatidylcholine (TOO-epoxyPLPC), in which the 12,13-epoxyperoxyl radicals derived from 13-PLPC-OOH attacked the 8a-position of the alpha-tocopheroxyl radical. The iron and ascorbate-catalyzed reaction of 13-PLPC-OOH with alpha-tocopherol in phosphatidylcholine (PC) liposomes was assessed by measuring the reaction products of alpha-tocopherol. When 13- PLPC-OOH and alpha-tocopherol were added in saturated dimyristoyl-PC liposomes, the products were TOO-epoxyPLPC, alpha-tocopherylquinone, and epoxy-alpha-tocopherylquinones. In 1-palmitoyl-2-linoleoyl-PC (PLPC) liposomes, alpha-tocopherol could react with both the 13-PLPC-OOH derived 12,13-epoxyperoxyl radicals and the PLPC-derived peroxyl radicals and formed the addition products together with a-tocopherylquinone and epoxy-alpha-tocopherylquinones. Therefore, the iron-catalyzed decomposition of phospholipid hydroperoxides primarily produces epoxyperoxyl radicals, which react with the 8a-carbon centered radical of alpha-tocopherol in liposomal systems.
