Physicochemical Characterization of Inclusion Complex of Catechin and Glucosyl-β-Cyclodextrin

Purpose: To investigate the suitability of glucosyl-β-cyclodextrin (G-β-CD) to form inclusion complex with catechin, and characterize the physicochemical properties of the inclusion complex of catechin and G-β-CD. Methods: Catechin and G-β-CD was mixed in water at the same molar ratio, stirred at 20 °C for 48 h and lyophilized to obtain the complex. Its physicochemical properties were investiga...

β-Cyclodextrin Inclusion Complex to Improve Physicochemical Properties of Pipemidic Acid: Characterization and Bioactivity Evaluation

The aptitude of cyclodextrins (CDs) to form host-guest complexes has prompted an increase in the development of new drug formulations. In this study, the inclusion complexes of pipemidic acid (HPPA), a therapeutic agent for urinary tract infections, with native β-CD were prepared in solid state by kneading method and confirmed by FT-IR and 1H NMR. The inclusion complex formation was also charac...

Solid State Characterization of Domperidone: Hydroxypropyl-β-Cyclodextrin Inclusion Complex

The purpose of the present study was to prepare inclusion complex of domperidone with hydroxylpropyl-β-cyclodextrin in order improved the solubility and hence to increase dissolution of domperidone. An effect of concentration of hydroxylpropyl-β-cyclodextrin on the aqueous solubility of domperidone was determined by phase-solubility method. The aqueous solubility of domperidone increased as a f...

Β-cyclodextrin Inclusion Complex of Curcumin

Formation of inclusion complex of curcumin with β-cyclodextrin ( β-CD) has been characterized by absorption and fluorescence spectroscopy. From temperature-dependent fluorescence measurements, the thermodynamic parameters ∆H and ∆S, for the complexation were estimated. Kinetics of binding was studied by stopped flow technique, from which the binding constants for inclusion complex was estimated...
