    摘要:
    扩大培养基中添加适当化合物可将Magnoliae酵母产生的细胞外糖脂产量提高三到五倍。这种添加剂可以是长链酸、酯、碳氢化合物或甘油酯,经过羟基化后转化为羟基脂肪酸索非酮苷。从C16到C22的所有链长的脂肪酯,包括几种不饱和酯,以及从C16到C24的偶数碳氢化合物都容易发酵。较短链的化合物使用效果不佳或根本不使用。对于含有16到18个碳原子的化合物,羟基化发生在末端或次末端碳原子上,取决于不饱和度和链长。含有超过18个碳原子的底物主要通过一个或多个二碳单位减少链长并进行羟基化,从而在次末端碳原子上带有羟基的C17或C18酸。讨论了发酵过程中发生的各种酶反应。

  • Sustained-release pranoprofen preparation
    申请人:SS PHARMACEUTICAL CO., LTD.
    公开号:EP0498372A1
    公开(公告)日:1992-08-12
    A sustained-release pranoprofen preparation is disclosed. The preparation comprises an effective amount of pranoprofen and one or more sustained-release components selected from the group consisting of oily components, water-soluble components, water-insoluble components, and intestinally soluble components. It controls release of pranoprofen and lowers the maximum pranoprofen concentration in blood, maintaining its concentration in blood at a certain level for a long period of time. It reduces risks of side effects and can effectively treat diseases with dosing once or twice a day.
    本发明公开了一种普拉洛芬缓释制剂。该制剂由有效量的普拉洛芬和一种或多种缓释成分组成,这些缓释成分选自油性成分、水溶性成分、水不溶性成分和肠溶性成分组成的组。它能控制普拉洛芬的释放,降低血液中普拉洛芬的最高浓度,使血液中的浓度长期保持在一定水平。它能降低副作用的风险,每天用药一到两次,就能有效治疗疾病。

    申请人:National Institute of Advanced Industrial Science and Technology
    公开号:EP1544190A1
    公开(公告)日:2005-06-22
    The present invention provides a safe, convenient and efficient method for producing carboxylic acid by a reaction of alicyclic alcohol with an aqueous hydrogen peroxide to thereby obtain carboxylic acid in high yield from alicyclic alcohol or alicyclic ketone under mild reaction conditions, wherein the reaction operation is simple and easy, a step for removing solvent after completion of the reaction is not necessary and influence and toxicity upon the environment and human body are markedly small. In order to provide it, an oily alicyclic alcohol is allowed to react with an aqueous hydrogen peroxide in the presence of a catalyst containing a metal compound belonging to Group 6 of the Periodic Table in a heterogeneous solution system.
    本发明提供了一种安全、方便、高效的生产羧酸的方法,该方法通过脂环醇与过氧化氢水溶液反应,从而在温和的反应条件下,从脂环醇或脂环酮中高产率地获得羧酸,反应操作简单易行,反应完成后无需去除溶剂的步骤,对环境和人体的影响和毒性明显较小。为了实现这一目标,需要在一个异相溶液体系中,在含有元素周期表第 6 族金属化合物的催化剂存在下,使油性脂环醇与过氧化氢水溶液发生反应。
