    Thermodynamic, IR spectral and X-ray diffraction studies of the “β-cyclodextrin-para-aminobenzoic acid” inclusion complex
    摘要:
    对氨基苯甲酸和β-环糊精之间的分子间相互作用形成了化学计量组成为1:1的包合物。通过 Ketelar 方程计算了“β-环糊精-对氨基苯甲酸”包合物在 289、292 和 313 K 下的稳定常数。考察了温度对“β-环糊精-对氨基苯甲酸”包合物稳定性的影响,并计算了参与络合物形成的热力学参数(ΔG、ΔH、ΔS)。 X 射线衍射和红外光谱研究证实了对氨基苯甲酸和 β-环糊精之间形成的超分子复合物。

  • Crystal structure determination of the β-cyclodextrin–p-aminobenzoic acid inclusion complex from powder X-ray diffraction data
    作者:Ping Guo、Yanhong Su、Qiang Cheng、Qingqing Pan、Hui Li

    日期:2011.5
    The 1:1 inclusion complex of beta-cyclodextrin and p-aminobenzoic acid was prepared and characterized by TG-DTA. The crystal structure of the complex was solved directly from powder X-ray diffraction data using the direct space approach and refined using Rietveld refinement techniques. The complex crystallizes in monoclinic P2(1) space group, with unit cell parameters a=20.7890A, b=10.2084A, c=15.1091A

  • Host–guest system of Vitamin B10 in β-cyclodextrin: characterization of the interaction in solution and in solid state

    Conventional drugs are usually formulated for the immediate release of the medicinal substances and for obtaining the desired therapeutic effect. The aim of this paper was to investigate the possible interactions between Vitamin B10 and β-cyclodextrin (β-CD), to determine the physical-chemical characteristics and the interactions present in the corresponding inclusion compound. The so-obtained compounds were characterized by X-ray diffraction, DSC and FTIR spectroscopy. 1H NMR and UV–vis spectroscopic methods were employed to study the inclusion process in aqueous solution. The X-ray powder diffraction patterns demonstrate the inclusion compound formation, especially for the lyophilized product where the amorphous phase dominates. The existence of the inclusion compounds obtained by different methods was confirmed by comparing with DSC and FTIR data of the pure compounds and the (1:1) Vitamin B10:β-CD physical mixture (pm). 1H NMR measurements on aqueous solutions of Vitamin B10 and β-CD in D2O allowed us to establish the corresponding Vitamin B10’s and cyclodextrin’s protons implied in the complexation process. 2D NMR spectroscopy established the geometry of the inclusion complex. 1H NMR, UV–Vis and fluorescence data were used to obtain the stoichiometry and the stability constant of the complex.
    传统药物的配制通常是为了立即释放药效物质并获得理想的治疗效果。本文旨在研究维生素 B10 与 β-环糊精(β-CD)之间可能存在的相互作用,确定相应包合物的物理化学特征和相互作用。获得的化合物通过 X 射线衍射、DSC 和傅立叶变换红外光谱进行了表征。采用 1H NMR 和 UV-vis 光谱法研究了溶液中的包合过程。X 射线粉末衍射图样证明了包合物的形成,尤其是在冻干产品中,无定形相占主导地位。通过比较纯化合物和(1:1)维生素 B10:β-CD 物理混合物(pm)的 DSC 和傅立叶变换红外光谱数据,证实了通过不同方法获得的包合物的存在。通过对维生素 B10 和 β-CD 在 D2O 中的溶液进行 1H NMR 测量,我们确定了络合过程中相应的维生素 B10 和环糊精质子。二维核磁共振光谱确定了包合物的几何形状。利用 1H NMR、UV-Vis 和荧光数据获得了该复合物的化学计量学和稳定常数。

    with a host:guest stoichiometry of 1:1, and that of the beta-cyclodextrin-o-aminobenzoic acid complex is P1 with a stoichiometry of 2:3. The different structures of the guest molecules lead to the different molecular packing structures of the two complexes. Intermolecular hydrogen-bond interactions are the main force that stabilize the supramolecular systems. In both crystals, there are water molecules
