    Antioxidant Activity of Hydroxytyrosol Acetate Compared with That of Other Olive Oil Polyphenols
    摘要:
    Hydroxytyrosol acetate was synthesized, and the antioxidant activity of this olive oil component was assessed in comparison with that of other olive oil components, namely hydroxytyrosol, oleuropein, 3,4-DHPEA-EA, and alpha -tocopherol in bulk oil and oil-in-water emulsions. The activity of the compounds was also assessed by scavenging of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals. Hydroxytyrosol acetate had a weaker DPPH radical scavenging activity than hydroxytyrosol, oleuropein, or 3,4-DHPEA-EA but it had a radical scavenging activity similar to that of cr-tocopherol. In oil, the antioxidant activity of hydroxytyrosol acetate was much higher than that of alpha -tocopherol or oleuropein, but in an emulsion S,4-DHPEA-EA and alpha -tocopherol were more effective as antioxidants than hydroxytyrosol acetate. The antioxidant activity of hydroxytyrosol acetate was rather similar to that of hydroxytyrosol in oil and emulsions despite the difference in DPPH radical scavenging activity.

  • Tyrosol and hydroxytyrosol derivatives as antitrypanosomal and antileishmanial agents
    作者:Efres Belmonte-Reche、Marta Martínez-García、Pablo Peñalver、Verónica Gómez-Pérez、Ricardo Lucas、Francisco Gamarro、José María Pérez-Victoria、Juan Carlos Morales

    Existing treatments have considerable side effects and increase resistance of the parasites. We have measured antitrypanosomal and antileishmanial activity of natural phenols, tyrosol (TYR) and hydroxytyrosol (HT) and several of their esters and metabolites. We found significant IC50 values against Trypanosoma brucei for HT decanoate ester and HT dodecanoate ester (0.6 and 0.36 μM, respectively). This represents
    锥虫病和利什曼病一直是非洲国家健康和发展的真正挑战。现有疗法具有相当大的副作用并增加了寄生虫的抵抗力。我们已经测量了天然酪醇(TYR)和羟基酪醇(HT)以及它们的一些酯和代谢物的抗胰锥虫和抗疟疾活性。我们发现针对布鲁氏锥虫的有效IC 50值用于HT癸酸酯和HT十二酸酯(分别为0.6和0.36μM)。这表示相对于HT的活性大大增加(分别为79和132倍)。此外,两种化合物均对非肿瘤性人类细胞系MRC-5(分别为118和106)表现出高选择性。然后,我们合成了一个有针对性的化合物库,以探索结构活性。我们发现HT癸酸酯和HT十二酸酯的醚和硫脲类似物在低微摩尔范围内也显示出针对布鲁氏杆菌的IC 50值。总之,二邻苯酚环和中等大小的烷基链对于活性至关重要,而它们之间化学键的性质似乎不太重要。

    of tyrosol (1) and hydroxytyrosol (2) from a phenolic extract obtained from the solid residue of olive milling. These three methods, which facilitated the recovery of these phenols, were chemical or enzymatic acetylation, benzylation, and carbomethoxylation, and subsequent carbonylation or acetonation reactions. Several new lipophilic alkyl-carbonate derivatives of hydroxytyrosol have been synthesized
    已经研究了三种方法,用于从从橄榄研磨的固体残留物中获得的酚类提取物中分离酪醇(1)和羟基酪醇(2)。这三种促进这些回收的方法是化学或酶促乙酰化,苄基化和碳甲氧基化,以及随后的羰基化或丙酮化反应。已经合成了几种新的羟基酪醇亲脂性烷基碳酸酯衍生物,使用具有不同链长的醇通过碳酸酯连接基偶联该的伯羟基。这些亲脂性衍生物的抗氧化性能已通过不同方法进行了评估,并与游离羟基酪醇进行了比较(2)以及著名的抗氧化剂BHT和α-生育酚。三种方法可用于测定这种抗氧化剂的活性:FRAP和ABTS测定法用于测试亲性介质中的抗氧化剂能力,而RAncimat试验则用于评估亲脂性基质中的抗氧化剂能力。这些新的羟基酪醇烷基碳酸酯衍生物增强了这种天然的抗氧化活性,其抗氧化性能也高于商业抗氧化剂BHT和α-生育酚。尽管最好的结果主要是通过在这种天然酚类物质的伯羟基上具有较长链的化合物获得的,但最佳的结果是侧链长度对2的

    Hydroxytyrosol and two other polyphenols of olive tree, hydroxytyrosol acetate and 3,4-dihydroxyphenylglycol, are known for a wide range of beneficial activities in human health and prevention from diseases. The inability to isolate high, pure amounts of these natural compounds and the difficult and laborious procedures for the synthesis of them led us to describe herein an efficient, easy, cheap, and scaling

  • High-Yielding Synthesis of Methyl Orthoformate-Protected Hydroxytyrosol and Its Use in Preparation of Hydroxytyrosyl Acetate
    作者:Augusto Gambacorta、Daniela Tofani、Antonella Migliorini

    the active principle under physiological conditions. The use of the methyl orthoformate-protected hydroxytyrosol allows the preparation of protected hydroxytyrosyl esters, like the acetate herein reported, by selective esterification of the alcoholic function. The subsequent quantitative deprotection under non-aqueous and mild conditions affords the hydroxytyrosyl acetate in high yields.
    抗氧化剂羟基酪醇(或 2-(3,4-二羟基苯基)乙醇)的新原甲酸甲酯已通过两步高产程序合成。这种保护可以稳定羟基酪醇,防止快速氧化,并允许简单的色谱纯化和长期储存。保护基团在 pH = 10 和低于 pH = 5 时解,从而允许在生理条件下释放活性成分。使用原甲酸甲酯保护的羟基酪醇允许通过醇官能团的选择性酯化来制备保护的羟基酪氨酸酯,如本文报道的乙酸酯。随后在非和温和条件下定量脱保护以高产率提供羟基酪乙酸酯。
