    摘要:
    羟基酪醇是一种天然存在的具有抗氧化性能的邻酚类化合物,它是通过三步高产率程序从天然和低成本的化合物(例如酪醇或高香草醇)合成的。首先,通过使用碳酸二甲酯(DMC)作为试剂/溶剂,对这些化合物的醇基进行有效的化学选择性保护。其次,用2-碘氧基苯甲酸(IBX)或Dess-Martin高碘烷试剂(DMP)氧化并用连二亚硫酸钠(Na 2 S 2 O 4)原位还原,可以制备羧甲基化羟基酪醇。最终,通过温和的水解步骤,以高收率和高纯度获得了羟基酪醇,这已通过NMR光谱和HPLC谱图得到了证实。通过类似的方法,亲脂性羟基酪醇衍生物被用作药物,食品,和化妆品制剂,都准备好了。实际上,首先,通过使用酰氯在没有任何催化剂的情况下对酪醇和高香草醇的醇基团进行化学选择性保护,以获得相应的亲脂性衍生物,然后将这些化合物以高收率和高纯度转化为羟基酪醇衍生物。 IBX或DMP和Na2S2O4的氧化/还原途径。

    摘要:
    评价了具有短,中和长酰基链的羟基酪氨酸酯减少脂多糖刺激的RAW264.7巨噬细胞减少一氧化氮(NO)产生的能力。在测试的化合物中,发现C18酯,即硬脂酸羟基酪氨酯(HtySte)和油酸羟基酪氨酯(HtyOle),以浓度依赖的方式降低NO的产生,而其他化合物(包括母体羟基酪醇)在测试浓度下无效。范围(0.5-5μM)。对HtyOle潜在的免疫调节特性的进一步研究表明,前列腺素E 2具有明显的浓度依赖性。生产。在转录水平上,HtyOle抑制诱导型NO合酶,环氧合酶2和白介素1β的表达。此外,通过高效液相色谱-质谱联用,首次在橄榄油副产品中鉴定出HtyOle。相比之下,完整橄榄中未发现HtyOle。我们的结果表明,HtyOle是在石油加工过程中形成的,代表了其中存在羟基酪醇的重要形式。

    antioxidants. Free fatty acids and fatty acid ethyl esters (substrate molar ratio tyrosol: acyl donor, 1:10) were used as acyl donors and immobilized lipase from Candida antarctica was the biocatalyst (10 %). The phenolipids were isolated and characterized using ESI–MS, 1H‐NMR, and 13C‐NMR. Peroxide value (PV) and para‐anisidine value (p‐AV) were measured to evaluate their antioxidant activities in bulk

  • Lipophilic (Hydroxy)phenylacetates by Solvent-Free Lipase-Catalyzed Esterification and Transesterification in Vacuo
    作者:Petra Weitkamp、Nikolaus Weber、Klaus Vosmann
    DOI:10.1021/jf8002224
    日期:2008.7.1
    Various long-chain alkyl (hydroxy)phenylacetates were prepared in high yield by lipase-catalyzed transesterification of the corresponding short-chain alkyl hydroxyphenyl acetates and fatty alcohols in equimolar ratios. The reactions were performed in vacuo at moderate temperatures in the absence of solvents and drying agents in direct contact with the reaction mixture. Immobilized lipase B from Candida antarctica(Novozym 435) was the most effective biocatalyst for the various transesterification reactions. Generally, Novozym 435-catalyzed transesterifications of short-chain alkyl (hydroxy)phenylacetates with long-chain alcohols led to higher conversions and enzyme activities than the corresponding esterifications. For example, the transesterification activity was up to 4-fold higher than the esterification activity for the formation of oleyl 4-hydroxy-3-methoxyphenylacetate using Novozym 435 as a biocatalyst. The relative transesterification activities were as follows: phenylacetate > 3-methoxyphenylacetate approximate to 4-methoxyphenylacetate > 4-hydroxy-3-methoxyphenylacetate > 3-hydroxyphenylacetate approximate to 4-hydroxyphenylacetate >> 2-methoxyphenylacetate >> 3,4-dihydroxyphenylacetate. With respect to the position of methoxy and hydroxy substituents, the transesterification activity of Novozym 435 decreased in the order meta approximate to para >> ortho. Compounds with inverse chemical structures, for example, tyrosyl oleate, were obtained by Novozym 435-catalyzed esterification and transesterification of fatty acids and their methyl esters, respectively, with 2-phenylethan-1-ols. In contrast to the transesterifications of short-chain alkyl (hydroxy)phenylacetates with fatty alcohols, higher conversions and enzyme activities were observed for the Novozym 435-catalyzed esterifications of (hydroxy)phenylethanols with long-chain fatty acids than the corresponding transesterifications with fatty acid methyl esters.
