    Manufacture of (5Z,8Z,11Z,13E)(15S)-15-Hydroxyeicosa-5,8,11,13-tetraenoic Acid Sodium Salt for Clinical Trials
    摘要:
    A robust synthesis of (5Z,8Z,11Z,13E)(15S)-15-hydroxyeicosa-5,8,11,13-tetraenoic acid (15(S)-HETE) sodium salt was established, utilising a biooxidalion process. Treatment of arachidonic acid with soybean lipoxidase in 0.1 M sodium tetraborate buffer under oxygen pressure resulted in formation of the hydroperoxide, 15(S)HPETE. Addition of sodium borohydride to the reaction mixture reduced the hydroperoxide to 15(S)-HETE, which was then purified by column chromatography. 15(S)-HETE sodium salt was prepared by treatment of an ethanol solution of HETE with aqueous sodium hydrogen carbonate. Multiple 10-g batches of 15(S)-HETE sodium salt with >98% enantiomeric excess and >98% chemical purity were prepared to support clinical trials.

    摘要:
    通过特定的脂氧合酶 (LOX) 将花生四烯酸氢过氧化物进一步转化为白三烯 A (LTA) 型环氧化物是炎症介质生物合成的关键步骤。尽管哺乳动物 5-LOX 将其主要产物(5S-氢过氧二十碳四烯酸;5S-HPETE)几乎完全转化为 LTA(4),但模型酶大豆 LOX-1 通常不会产生可检测到的白三烯,而是进一步氧化其主要产物 15S- HPETE 为 5,15- 和 8,15-二氢过氧化物。哺乳动物 15-LOX-1 显示这两种类型的活性。我们推断,LOX 活性位点内分子氧的可用性有利于氧合作用,而 O(2) 的缺乏则促进 LTA 环氧化物的合成。为了测试这一点,我们在厌氧条件下使 15S-HPETE 与大豆 LOX-1 反应,并通过高压液相色谱、紫外、质谱和核磁共振鉴定产物。在这些产品中,我们鉴定了一对具有全反式共轭三烯的 8,15-二羟基非对映体,它们在 C-8 处从 H(2)(18)O

    Lipid peroxidation of polyunsaturated fatty acids and esters leads to a complex mixture of hydroperoxides and cyclic peroxides, some of which possess potent biological activity. These product mixtures contain dozens of diastereomers and regioisomers. The technique of coordination ion spray−mass spectrometry (CIS−MS), recently reported by Bayer and collaborators, proves to be a powerful tool for the

  • The hydroperoxide moiety of aliphatic lipid hydroperoxides is not affected by hypochlorous acid

    The oxidation of polyunsaturated fatty acids to the corresponding hydroperoxide by plant and animal lipoxygenases is an important step for the generation of bioactive lipid mediators. Thereby fatty acid hydroperoxide represent a common intermediate, also in human innate immune cells, like neutrophil granulocytes. In these cells a further key component is the heme protein myeloperoxidase producing HOCl
    植物和动物脂氧化酶将多不饱和脂肪酸氧化成相应的氢过氧化物是产生生物活性脂质介体的重要步骤。因此,脂肪酸氢过氧化物也代表了人类天然免疫细胞(如嗜中性粒细胞)中的常见中间体。在这些细胞中,另一个关键成分是血红素蛋白髓过氧化物酶,可产生HOCl作为反应性氧化剂。根据不同的研究,可以假定脂肪酸氢过氧化物与次氯酸(HOCl)反应。在这里,色谱和光谱分析显示15S-氢过氧-5Z,8Z,11Z,13E-二十碳四烯酸(15-HpETE)和13S-氢过氧-9Z,11E-的氢过氧化物部分十八碳二烯酸(13-HpODE)不受HOCl影响。由于与HOCl的反应,无法测量氢过氧化物基团的还原。可以证明,脂肪酸氢过氧化物的双键是HOCl的主要目标,HOCl以试剂形式存在或由髓过氧化物酶-过氧化氢-化物系统形成。
  • Synthesis of 11-thialinoleic acid and 14-thialinoleic acid, inhibitors of soybean and human lipoxygenases

    Lipoxygenases catalyse the oxidation of polyunsaturated fatty acids and have been invoked in many diseases including cancer, atherosclerosis and Alzheimer's disease. Currently, no X-ray structures are available with substrate or substrate analogues bound in a productive conformation. Such structures would be very useful for examining interactions between substrate and active site residues. Reported here are the syntheses of linoleic acid analogues containing a sulfur atom at the 11 or 14 positions. The key steps in the syntheses were the incorporation of sulfur using nucleophilic attack of metallated alkynes on electrophilic sulfur compounds and the subsequent stereospecific tantalum-mediated reduction of the alkynylsulfide to the cis-alkenylsulfide. Kinetic assays performed with soybean lipoxygenase-1 showed that both 11-thialinoleic acid and 14-thialinoleic acid were competitive inhibitors with respect to linoleic acid with Ki values of 22 and 35 μM, respectively. On the other hand, 11-thialinoleic acid was a noncompetitive inhibitor with respect to arachidonic acid with Kis and Kii values of 48 and 36 μM, respectively. 11-Thialinoleic acid was also a noncompetitive inhibitor of human 15-lipoxygenase-1 with arachidonic acid (Kis = 11.4 μM, Kii = 18.1 μM) or linoleic acid as substrate (Kis = 20.1 μM, Kii = 20.0 μM), and a competitive inhibitor of human 12-lipoxygenase with arachidonic acid as substrate (Ki = 2.5 μM). The presence of inhibitor did not change the regioselectivity of soybean lipoxygenase-1, human 12- or 15-lipoxygenase-1.
    脂氧酶催化多不饱和脂肪酸的氧化反应,并被认为与多种疾病相关,包括癌症、动脉粥样硬化和阿尔茨海默病。目前,尚无与底物或底物类似物结合的有效构象的X射线结构数据。此类结构对于研究底物与活性位点残基之间的相互作用非常有用。本文报道了在11或14位含有原子的亚油酸类似物的合成。合成中的关键步骤包括使用属化炔烃的亲核攻击将并入到亲电性化合物中,随后通过介导的立体特异性还原将炔醚还原为顺式烯醚。使用大豆脂氧酶-1进行的动力学测定显示,11-亚油酸和14-亚油酸亚油酸的抑制作用分别为竞争性抑制,其Ki值分别为22和35μM。另一方面,11-亚油酸花生四烯酸的抑制作用为非竞争性抑制,其Kis和Kii值分别为48和36μM。11-亚油酸对人类15-脂氧酶-1(以花生四烯酸为底物时,Kis = 11.4μM,Kii = 18.1μM;以亚油酸为底物时,Kis = 20.1μM,Kii = 20.0μM)的抑制作用也是非竞争性的,并且对以花生四烯酸为底物的人类12-脂氧酶具有竞争性抑制作用(Ki = 2.5μM)。抑制剂的存在并未改变大豆脂氧酶-1、人类12-或15-脂氧酶-1的区域选择性。
  • Synthesis of hydroperoxide and perketal derivatives of polyunsaturated fatty acids as potential antimalarial agents

    Hydroperoxide derivatives of β-oxa-substituted polyunsaturated fatty acids were prepared by 15-lipoxygenase catalysed oxidation and perketal derivatives of fatty acid hydroperoxides were synthesized. The perketals are more stable than their parent fatty acid hydroperoxides, but less active as antimalarial agents in the in vitro growth inhibition of Plasmodium falciparum.
