    摘要:
    描述了一种简单的方法来修饰环糊精(CD)的主表面。α-,β-和γ-CD的6 I - O-基通过分子内的1,8-氢原子转移反应,通过区域选择性地抽象化位于相邻D-葡萄糖单元中的H5 II受限制的九元过渡态产生稳定的1,3,5-三氧杂环丁烷环。该反应已扩展至α-和β-CD的1,4-二醇,得到了相应的双(三氧杂环丁烷)。C 2对应于α-CD的对称双(三恶烷)是稳定的结晶固体,其结构已通过X射线衍射分析确定。计算出的几何参数证实该轮辋的主面朝着较窄的椭圆形严重变形。

  • Simple cyclodextrin aldehydes as excellent artificial oxidases
    作者:Thomas Hauch Fenger、Mikael Bols
    DOI:10.1007/s10847-010-9771-y
    日期:2011.4
    Cyclodextrin based oxidases, with a ketone as functional group are well known as good artificial enzyme mimics (Fenger et al. Org Biomol Chem 7:933–943; Marinescu and Bols Angew Chem Int Ed 45:4590–4593; Bjerre et al. Eur J Org Chem 704–710; Marinescu et al. J Am Chem Soc 127:17578–17579). We here report a series of modified cyclodextrins, having aldehydes as functional groups. The aldehyde based artificial enzymes have, in most cases, better catalysis than the ketones, because of their powerful covalent binding of hydrogen peroxide. Among the modified cyclodextrins studied are mono and di aldehydes on the 6 positions, with or without methylated hydroxyl groups. The aldehyde functionality was also introduced close to the secondary side, by attaching ethoxy-2-al or propoxy-3-al to the 2 position. The modified cyclodextrins showed excellent enzymatic activity towards oxidation of different aminophenols, and 4-methoxy benzyl alcohol with hydrogen peroxide as a stoichiometric oxidant. Rate enhancements up to 4,600 were achieved for oxidation of 4-methoxy benzyl alcohol, where as oxidation of amines gave rate enhancements up to 3,400. The artificial oxidases catalyses oxidations under enzymatic conditions (water, pH 7, 25 °C), following Michaelis–Menten kinetics. To confirm the enzyme activity, inhibition studies with sodium naphthalene-2-sulfonate were carried out. These studies showed competitive inhibition of the enzymes, verifying the cyclodextrins enzyme like character.
    众所周知,以酮为官能团的环糊精氧化酶是良好的人工酶模拟物(Fenger et al.Org Biomol Chem 7:933-943; Marinescu and Bols Angew Chem Int Ed 45:4590-4593; Bjerre et al.Eur J Org Chem 704-710; Marinescu et al.J Am Chem Soc 127:17578-17579)。我们在此报告了一系列以醛为官能团的改性环糊精。在大多数情况下,以醛为基础的人工酶比酮类具有更好的催化作用,因为它们能与过氧化氢产生强大的共价结合。在所研究的改性环糊精中,有 6 个位置上的单醛和二醛,有或没有甲基化羟基。此外,还通过在 2 位上连接乙氧基-2-al 或丙氧基-3-al,在靠近仲侧的位置引入了醛官能团。修饰后的环糊精对不同氨基苯酚和 4-甲氧基苯甲醇(以过氧化氢作为定量氧化剂)的氧化显示出卓越的酶活性。氧化 4-甲氧基苯甲醇的速率可提高到 4 600,而氧化胺的速率可提高到 3 400。人工氧化酶在酶促条件下(、pH 值 7、25 °C),按照 Michaelis-Menten 动力学催化氧化。为了证实酶的活性,还用萘-2-磺酸钠进行了抑制研究。这些研究显示了对酶的竞争性抑制,验证了环糊精的酶类似特性。
