    亚油酸二醇合酶(LDS)的环氧合酶(COX)和8 R-双加氧酶(8 R -DOX)活性是同源的血红素依赖性酶,可通过酪氨酰基自由基介导的氢提取和O 2的对映插入而使脂肪酸氧化。大豆脂氧合酶-1(sLOX-1)包含非血红素铁,并以大的氘动力学同位素效应(D-KIE)氧化18:2n-6。本工作的目的是通过使用一系列n-6和n-9脂肪酸并通过D-KIE分析来获得对这些酶作用的进一步的机理认识。COX-1氧化的C 20和C 18脂肪酸按以下顺序排列:20:2n-6> 20:1n-6> 20:3n-9> 20:1n-9和18:3n-3≥18:2n-6> 18:1n-6 18:2n-6及其几何异构体(9 E,12 Z)18:2都主要在C-9处被COX-1氧化,但9 Z,12 E异构体大部分在C-13处被氧化。因此,在n-6位的顺式构型双键对于底物的定位很重要。与18:2n-6类似,8 R -DOX在C-8处氧化(9

  • Enantioselective formation of an α, β-epoxy alcohol by reaction of methyl 13(<i>S</i>)-hydroperoxy-9(<i>Z</i>), 11(<i>E</i>)-octadecadienoate with titanium isopropoxide

    AbstractMethyl 11(R), 12(R)‐epoxy‐13(S)‐hydroxy‐9(Z)‐octadecenoate (threo isomer) was generated from linoleic acid by the sequential action of an enzyme and two chemical reagents. Linoleic acid was treated with lipoxygenase to yield its corresponding hydroperoxide [13(S)‐hydroperoxy‐9(Z), 11(E)‐octadecadienoic acid]. After methylation with CH2N2, the hydroperoxide was treated with titanium (IV) isopropoxide [Ti(O‐i‐Pr)4] at 5°C for 1 h. The products were separated by normal‐phase high‐performance liquid chromatography and characterized with gas chromatography‐mass spectrometry, infrared spectroscopy, and nuclear magnetic resonance spectroscopy. Approximately 30% of the product was methyl 13(S)‐hydroxy‐9(Z), 11(E)‐octadecadienoate. Over 60% of the isolated product was methyl 11(R), 12(R)‐epoxy‐13(S)‐hydroxy‐9(Z)‐octadecenoate. After quenching Ti(O‐i‐Pr)4 with water, the spent catalyst could be removed from the fatty products by partitioning between CH2Cl2 and water. These results demonstrate that Ti(O‐i‐Pr)4 selectively promotes the formation of an α‐epoxide with the threo configuration. It was critically important to start with dry methyl 13(S)‐hydroperoxy‐9(Z),11(E)‐octadecadienoate because the presence of small amounts of water in the reaction medium resulted in the complete hydrolysis of epoxy alcohol to trihydroxy products.

COX-1 oxidized C20 and C18 fatty acids in the following order of rates: 20:2n  6 > 20:1n  6 > 20:3n  9 > 20:1n  9 and 18:3n  3 ≥ 18:2n  6 > 18:1n  6. 18:2n  6 and its geometrical isomer (9E,12Z)18:2 were both mainly oxygenated at C-9 by COX-1, but the 9Z,12E isomer was mostly oxygenated at C-13. A cis-configured double bond in the n  6 position therefore seems important for substrate
