    摘要:
    使用核磁共振 (NMR) 光谱研究了神经毒素四亚甲基二磺四胺 (TETS) 与天然和改性环糊精 (CyD) 之间形成的包合物的结合化学计量、强度和结构。在所有六个检查案例中,发现了天然β-环糊精(β-CyD)及其化学修饰的对应物七肽-(2,3,6-tris-(2-羟丙基))-β-环糊精(2HP-β-CyD)最强烈地与 TETS 关联,这反映在它们的结合常数的大小上(β-CyD 的 K = 537 ± 26 M-1 和 2HP-β-CyD 的 K = 514 ± 49 M-1)。二维旋转框架 Overhauser 效应光谱 NMR 实验证实 TETS 分子与 β-CyD 和 2HP-β-CyD 作为分子间的紧密接近,鉴定了位于 CyD 腔内部的 H3 和 H5 质子与 TETS 的亚甲基质子之间的空间相互作用。版权所有 © 2012 John Wiley & Sons, Ltd.

    extensively; they can form stable complexes with several mycotoxins, including ZEN. However, information is limited regarding the interactions of CDs with ZOLs. Therefore, we studied the interactions of α- and β-ZOLs with native and six chemically modified β-CDs by fluorescence spectroscopy. Fluorescence enhancement during complex formation, as well as binding constants, were determined. To understand
    玉米赤霉烯酮 (ZEN) 是一种由镰刀菌产生的霉菌毒素。ZEN 主要污染不同的谷物,并对动物和人类产生强烈的异种雌激素作用。ZEN 是一种荧光真菌毒素,尽管分子相​​互作用和微环境变化会显着改变其光谱特性。在生物转化过程中,ZEN 被转化为 α-玉米赤霉烯醇 (α-ZOL) 和 β-玉米赤霉烯醇 (β-ZOL),它们是 ZEN 的有毒代谢物,可模拟雌激素的作用。环糊精 (CD) 是宿主分子,已被广泛研究。它们可以与多种霉菌毒素(包括 ZEN)形成稳定的复合物。然而,关于 CD 与 ZOL 相互作用的信息有限。因此,我们通过荧光光谱研究了 α- 和 β-ZOL 与天然和六种化学修饰的 β-CD 的相互作用。确定了复合物形成过程中的荧光增强以及结合常数。为了更好地了解 ZOL-CD 相互作用,还进行了分子建模研究。两种霉菌毒素衍生物与甲基化和磺丁基化 CD 衍生物形成最稳定的复合物;然而,α-ZOL

  • An investigation into the preparation, characterization and antioxidant activity of puerarin/cyclodextrin inclusion complexes
    作者:Shujing Li、Junzhi Yue、Wei Zhou、Li Li

    The inclusion complexes between puerarin and three cyclodextrins (CDs), namely β-cyclodextrin (β-CD), (2-hydroxy)propyl-β-cyclodextrin (HP-β-CD, DS = 4.2) and methyl-β-cyclodextrin (Me-β-CD, DS = 12.5) were prepared. The effects of the complexation on the stability of puerarin were investigated in both solution and the solid state by methods of phase solubility study, XRD, DSC and SEM. Furthermore, the antioxidant activities of puerarin and puerarin/CDs inclusion complexes were determined by reducing power and 1,1-diphenyl-2-picryl-hydrazyl methods. Results showed that puerarin formed 1:1 stoichiometric inclusion complexes with β-CD, HP-β-CD and Me-β-CD. Additionally, the solubility and thermal stability of puerarin was improved after encapsulating by CDs. Antioxidant activity studies showed that the antioxidant performance of the inclusion complex was better than the native puerarin, and puerarin/Me-β-CD complex was the most effective form. It can be a potentially promising way to develop a new formulation of puerarin for herbal medicine or healthcare products.

  • NMR studies of interactions of new CB2 cannabinoid receptor ligands with cyclodextrins hosts. Correlation with micellar electrokinetic chromatography and reversed phase high performance liquid chromatography
    作者:Nathalie Azaroual、Jamal El Bakali、Delphine Broc、Carole Deghaye、Amaury Farce、Philippe Chavatte、Régis Millet、Claude Vaccher、Emmanuelle Lipka-Belloli

    Three selective CB2 cannabinoid receptor ligands have recently been discovered to be promising anti-inflammatory agents but their low water solubility hinder their per os administration. The popularity of the cyclodextrins, from a pharmaceutical standpoint lies on their ability to interact with poorly water-soluble drugs and improve their solubility. Herein, three experimental approaches for calculating the stability constant of complexes between the selective CB2 ligands and either the β-CD or the HP-β-CD, were tested: nuclear magnetic resonance, micellar electrokinetic chromatography and high performance liquid chromatography in reversed phase. In NMR studies the calculated K values were relatively high and were between 1486 and 3571 M−1 with β-CD. With HP-β-CD they were between 1203 and 2650 M−1. Concerning the two others techniques the K values were found lower. In MECK studies with β-CD they were between 308 and 792 M−1 and with HP-β-CD between 124 and 764 M−1. Finally in RP-HPLC studies with β-CD, they were between 539 and 1144 M−1 and with HP-β-CD between 196 and 396 M−1. These calculated constants suggest that a complexation phenomenon occurs. A model for inclusion of one of the CB2 ligands in the β-CD was then proposed from molecular modeling studies.
    最近发现的三种选择性 CB2 大麻受体配体是很有前途的抗炎药物,但它们的水溶性很低,妨碍了它们的口服给药。从制药的角度来看,环糊精的受欢迎程度在于它们能与水溶性较差的药物相互作用,提高药物的溶解度。在此,我们测试了三种计算选择性 CB2 配体与 β-CD 或 HP-β-CD 复合物稳定性常数的实验方法:核磁共振、胶束电动色谱法和反相高效液相色谱法。在核磁共振研究中,β-CD 的计算 K 值相对较高,介于 1486 和 3571 M-1 之间。HP-β-CD 的 K 值介于 1203 和 2650 M-1 之间。其他两种技术的 K 值较低。在使用 β-CD 进行的 MECK 研究中,K 值介于 308 和 792 M-1 之间;在使用 HP-β-CD 进行的 MECK 研究中,K 值介于 124 和 764 M-1 之间。最后,在与 β-CD 的 RP-HPLC 研究中,它们介于 539 和 1144 M-1 之间,而与 HP-β-CD 则介于 196 和 396 M-1 之间。这些计算常数表明存在络合现象。随后,通过分子建模研究提出了在 β-CD 中加入一种 CB2 配体的模型。
