制备方法与用途

二十二碳六烯酸乙酯DHA)是一种由微藻油制成、浓度为90%的化合物,通过诱导小鼠纹状体脂质过氧化而增强6-羟基多巴胺引起的神经元损伤。作为细胞膜的关键成分,DHA因其双键化学结构可被诱导发生过氧化反应。尽管如此,二十二碳六烯酸DHA)还具有神经保护作用[1][2]。

  • Site-Specific Deuteration of Polyunsaturated Alkenes
    作者:A. V. Smarun、M. Petković、M. S. Shchepinov、D. Vidović

    and expensive syntheses. In this report, we disclose a very efficient catalytic protocol for site-specific deuteration of PUFAs and analogous poly-alkenes under exceptional kinetic control. Deuterium oxide (D2O) has been identified not only as a deuterium source but also as a crucial component in the overall reaction mechanism responsible for averting the formation of thermodynamically favored side-products
    药物和生物学相关分子的选择性化在制药行业中变得越来越重要。多不饱和脂肪酸(PUFA)在其双烯丙基位点的位点选择性同位素增强已被认为是防止这些分子氧化损伤的一种独特方法,这种氧化损伤与神经元和视网膜疾病,动脉粥样硬化和衰老有关。用于制备位点选择性代PUFA的典型方法需要相当长,费力且昂贵的合成。在这份报告中,我们公开了非常有效的催化方案,用于在特殊动力学控制下对PUFA和类似聚烯烃进行位点特异性化。氧化(D 2O)不仅被认为是源,而且在整个反应机制中也起着至关重要的作用,该机制负责避免形成热力学上有利的副产物。

    The invention relates to the manufacture of certain polyunsaturated compounds employing a particular application of the Mitsonobu reaction in the presence of at least one anti-oxidant. We have found a method of making a pharmaceutically-acccptable polyunsaturated ester or thioester compound directly, which can ultimately be converted to the advantageous ketone compounds, in which unwanted oxidation and cis/trans isomerization are substantially reduced or eliminated using particular Mitsonobu chemistry.
