NMR Study on the Inclusion Complexes of β-Cyclodextrin with Isoflavones

NMR Study on the Inclusion Complexes of β-Cyclodextrin with Isoflavones.

The structure of the inclusion complexes of β-cyclodextrin (β-CD) with daidzein and daidzin in D2O were investigated using NMR spectroscopy. For the β-CD and daidzein system, two types of 1:1 complexes were formed with the daidzein deeply inserted into the CD cavity with different orientations. For the β-CD/daidzin system, a 1:1 complex was formed with the flavonoid part of daidzin entering the...

Thermodynamic, spectral and antimicrobial activity of inclusion complexes of acridone and its oxime with β-cyclodextrin

One of the methods to enhance bio-accessibility of drugs like Acridone and its oxime is toform inclusion complexes with β-cyclodextrin. The formation of such complexes has beenconfirmed by changes in spectral characteristics and melting point data. The aqueous phasesolubility studies reveal 1:1 stoichiometry between the compound and, β-cyclodextrin. The studyof thermodynamic parameters like ΔG,...

NMR spectroscopic characterization of β- cyclodextrin inclusion complex with vanillin

Inclusion Complexes of Promethazine with Monochlorotriazinyl-β-cyclodextrin

Formation of inclusion complexes of monochlorotriazinyl-β-cyclodextrin with promethazine was studied, for establishing the optimal conditions of their formation, in view of subsequent grafting on cellulose textiles with potential medicinal use. The infrared spectral study of inclusion in solid state indicated that the complex can be even formed by physically mixing the two substances. By the co...

Molecular modeling of β-cyclodextrin inclusion complexes with pharmaceutical compounds

Ten molecularly diverse compounds, selected on the basis of the standard free energy of complexation with β-cyclodextrin, have been used as training set of molecular docking experiments. After the conformational search of each compound the Molecular Interaction Evaluation (MOLINE) program has been adopted to generate the inclusion geometries. The recognition process has been thermodynamically e...
