    Synthesis of linoleic acid with chiral isotopic labelling at a flanking and a medial allylic methylene: the (8R,9Z,12Z)-[8-2H] and (11R,9Z,12Z)-[11-2H]-stereoisomers, and (Z)-[2,2-2H2]non-3-enal
    摘要:
    [1-H-2]Oct-2-ynal is converted by fermenting bakers' yeast into (1S)-[1-H-2]oct-2-yn-l-ol with an enantiomeric purity of > 96% as measured by Mosher's MTPA method. The alcohol, as its tosyl ester, was then converted by copper-catalysed coupling with the di-Grignard of dec-9-ynoic acid and catalytic semi-hydrogenation, into (11R)-[11-H-2]linoleic acid having less than 2% E-material and >95 atom %D. Provision for (11S)-[11-H-2]linoleic acid was made by configurational inversion of (1R) - [1-H-2]oct-2-yn-1-ol using Mitsunobu chemistry. (8R)-[8-H-2]Linoleic acid is made by a similar approach, the labelled chiral centre being formed on (8S)-8-hydroxy-[8-H-2]octanoic acid (> 96% ee). Reaction of the corresponding tosate with lithium acetylide-ethylenediamine complex gave, with configurational inversion, (8R)-[8-H-2]dec-9-ynoic acid, built into (8R)-[8-H-2]linoleic acid. A degradative circuit is applied to estimate the extent of configurational inversion in the displacement. Mitsunobu inversion of the (8S)-8-hydroxy compound provides access to (8S)-[8-H-2]linoleic acid. (Z)-Non-3-enal, a labile aldehyde from the enzymic degradation of linoleic acid, is made in [2,2-H-2(2)]-labelled form by a synthesis which uses, as a key step, the reaction between triheptynylborane and deuteriodiazoacetic ester.

    氘动力学同位素效应和底物类似物的氧化作用对环氧合酶,亚油酸二醇合酶和脂氧合酶的新见解
    摘要:
    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

    Variations on an oxidative theme: The precision with which FAD2‐type desaturases carry out CH activation reactions on flexible lipidic substrates is astonishing. The conformational space available within the active site of these enzymes has been explored using deuterium‐labeled substrates, and evidence for a novel quasi‐eclipsed conformer has been uncovered. The scheme shows some prototypical substrate

While previous labeling strategies have focused on deuterium labeling to ascertain the primary and secondary kinetic isotope effects for this reaction, there is an emerging interest and need for selectively enriched 13C isotopologues. In this report, we present synthetic strategies for site-specific 13C labeled linoleic acid substrates. We take advantage of a Corey-Fuchs
    大豆脂加氧酶-1(SLO-1)催化亚油酸中活性碳(C-11)的CH提取,这是烷基氢过氧化物形成的第一步和决定速率的步骤。虽然先前的标记策略集中于氘标记以确定该反应的主要和次要动力学同位素效应,但人们对新兴的兴趣和对选择性富集13C同位素的需求。在本报告中,我们介绍了针对位点特异性13C标记的亚油酸底物的合成策略。我们利用Corey-Fuchs甲酰基将13CBr4用作标记源,将其转化为末端13C标记的炔烃,以减少以前的脂肪酸13C合成标记方法的步骤数。

    metabolites of GLA, we synthesized several deuterated GLAs and evaluated their metabolism and cytotoxicity towards normal human fibroblast WI-38 cells and VA-13 tumor cells generated from WI-38 by transformation with SV40 virus. Deuteration of GLA suppressed both metabolism and cytotoxicity towards WI-38 cells and increased the selectivity for VA-13 cells. Fully deuterated GLA was visualized by Raman imaging
    据报道,γ-亚麻酸(GLA)通过未知的机制显示出肿瘤选择性的细胞毒性。在这里,为了评估GLA氧化代谢产物的参与,我们合成了几种氘代GLA,并评估了它们对正常人成纤维细胞WI-38细胞和通过SV40病毒转化从WI-38产生的VA-13肿瘤细胞的代谢和细胞毒性。GLA的氘化抑制了对WI-38细胞的代谢和细胞毒性,并增加了对VA-13细胞的选择性。通过拉曼成像观察到完全氘化的GLA,这表明GLA积累在VA-13细胞的细胞内脂质小滴中。我们的结果表明,肿瘤选择性细胞毒性是由于GLA本身而不是其氧化代谢产物所致。

    measurement of secondary deuterium (2° (2)H) and carbon-13 ((13)C) kinetic isotope effects (KIEs) at positions 9-13 within the substrate linoleic acid (LA) of soybean lipoxygenase-1. The KIEs have been measured using LA labeled with either protium (11,11-h2-LA) or deuterium (11,11-d2-LA) at the reactive C11 position, which has been previously shown to yield a primary deuterium isotope effect of ca.

Here we report the synthesis of linoleic acid and (11,11)-d2-linoleic acid which are combinatorially labeled at the vinylic positions (9, 10, 12, and 13). Combinatorial labeling schemes allow for the simultaneous determination of KIEs in enzymatic reactions using NMR. Substrates are, thus, available
