    (E)-Retinoic acid (RA) was shown to stimulate the rate of 2,2'-azobis(2-amidinopropane) (AAPH)-initiated autoxidation of linoleic acid (18:2) in sodium dodecyl sulfate (SDS) micelles. RA-dependent stimulation of 18:2 autoxidation was characterized by enhanced rates of dioxygen uptake which were linear with retinoid concentration. In contrast, 5,6-epoxy-RA, a major oxidation product of RA, failed to

    Abstract Objectives

    Lipoxygenases (LOX) are the key enzymes involved in the biosynthesis of leukotrienes and reactive oxygen species, which are implicated in pathophysiology of inflammatory disorders. This study was conducted to evaluate the inhibitory effect of water-soluble antioxidant ascorbic acid and its lipophilic derivative, ascorbic acid 6-palmitate (Vcpal) on polymorphonuclear lymphocyte 5-LOX and soybean 15-LOX (sLOX) in vitro.

    Methods

    LOX activity was determined by measuring the end products, 5-hydroperoxy eicosatetraenoic acid (5-HETE) and lipid hydroperoxides, by spectrophotometric and high performance liquid chromatography methods. The substrate-dependent enzyme kinetics and docking studies were carried out to understand the nature of inhibition.

    Key findings

    Vcpal potently inhibited 5-LOX when compared with its inhibitory effect on sLOX (IC50; 2.5 and 10.3 μm respectively, P = 0.003). Further, Vcpal inhibited 5-LOX more strongly than the known synthetic drugs: phenidone and nordihydroguaiaretic acid (P = 0.0007). Enzyme kinetic studies demonstrated Vcpal as a non-competitive reversible inhibitor of 5-LOX. In-silico molecular docking revealed high MolDock and Rerank score for Vcpal than ascorbic acid, complementing in-vitro results.

    Conclusion

    Both in-vitro and docking studies demonstrated Vcpal but not ascorbic acid as a non-competitive inhibitor of 5-LOX- and sLOX-induced lipid peroxidation, suggesting a key role for lipophilic nature in bringing about inhibition.

    摘要 目的

    脂氧合酶(LOX)是参与白三烯和活性氧自由基生物合成的关键酶,与炎症性疾病的病理生理学有关。本研究旨在评估水溶性抗氧化剂抗坏血酸及其亲脂性衍生物抗坏血酸6-棕榈酸酯(Vcpal)对体外多形核淋巴细胞5-LOX和大豆15-LOX(sLOX)的抑制作用。

    方法

    通过分光光度法和高效液相色谱法测定LOX活性,测量5-羟过氧基二十碳四烯酸(5-HETE)和脂质过氧化物的产物。进行基质依赖型酶动力学和对接研究,以了解抑制的性质。

    关键发现

    与对sLOX的抑制效果相比,Vcpal强力抑制5-LOX(IC50分别为2.5和10.3μm,P=0.003)。此外,Vcpal比已知的合成药物苯哌酮和诺地醌酸(P=0.0007)更强烈地抑制5-LOX。酶动力学研究表明Vcpal是5-LOX的非竞争性可逆抑制剂。体外分子对接显示,相较于抗坏血酸,Vcpal具有较高的MolDock和Rerank分数,与体内结果相互印证。

    结论

    体外和对接研究均表明Vcpal而不是抗坏血酸是5-LOX和sLOX诱导的脂质过氧化的非竞争性抑制剂,提示亲脂性质在抑制过程中起关键作用。

    The radical scavenging reactions of a vitamin E model compound, 2, 2, 5, 7, 8-pentamethylchroman-6-ol, with radicals from the Fe (II)-induced decomposition of a linoleic acid hydroperoxide, (9Z, 11E)-13-hydroperoxy-9, 11-octadecadienoic acid, were examined extensively.

The hydroxymethoxy acids are presumed to be derived from the epoxy acids. A possible reaction pathway for the formation of the products is discussed.

    Rate constants for autoxidation propagation of several unsaturated lipids in benzene solution at 37 degrees C and in phosphatidylcholine liposomes were determined by a linoleate radical clock.
