Fluorescence study on inclusion interaction of duloxetine in β-cyclodextrin shows significant increase in the fluorescence of duloxetine in the presence of β-cyclodextrin. The effects of pH and cyclodextrin concentration on the fluorescence spectra are reported. Fluorescence spectroscopy of the host-guest interaction between duloxetine and β-cyclodextrin shows formation of inclusion complex wit...

Objective: To develop a simple and cost effective chiral HPLC method for the separation of citalopram (CIT) enantiomers using chiral mobile phase additives (CMPAs). Methods: Sulfated beta cyclodextrin (S-β-CD) was synthesized in our laboratory and was evaluated as a CMPA. The parameters affecting the resolution were optimized. CIT enantiomers were resolved on an achiral Kromasil C8 column (150 ...

AIM Caffeic acid has been described as active against bacteria commonly isolated from wound infections. However, its low stability and poor solubility reduce caffeic acid applicability as a pharmaceutical product. These parameters can be enhanced by complexation with cyclodextrin. The main goal of the present work was to incorporate caffeic acid on cyclodextrin-based hydrogels capable of contro...

in this study, blueberry essential oil as a core material was microencapsulated with inulin and β-cyclodextrin at a ratio of 1:5 (core: wall). oil in water nano-emulsions were prepared by ultrasonic liquid processors and then transformed to encapsulate powder in spray dryer. dried powder was stored at 4 ˚c in refrigerator for determining moisture, encapsulation efficiency and morphology prop...

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,...

Soft attachment of streptavidin to β-cyclodextrin-modified pegylated SAMs was efficiently performed in a reversible and repetitive way via orthogonal bifunctional linkers involving streptavidin-biotin recognition and redox-driven multivalent host-guest (β-cyclodextrin-ferrocene) interactions.

A green chiral lab-on-a-chip cyclodextrin-based microchip electrophoretic method was developed for enantioseparation of baclofen (BCN) and phenylalanine (Phe) enantiomers the first time. All BCN Phe were offline labeled with 4-fluoro-7-nitrobenzofurazan (NBD-F) or fluorescein-5-isothiocyanate (FITC) fluorogenic reagents prior to microfluidic injection in a dynamically coated polymethylmethacryl...

Finasteride (FIN) is a Class II candidate of the Biopharmaceutics Classification System (BCS). The lipophilic cavity of cyclodextrins (CyDs) enables it to construct a non-covalent inclusion complex with different insoluble drugs. Only β-cyclodextrin (β-CyD) and hydroxypropyl-β-CyD (HP-β-CyD) have been previously examined with FIN. This study aimed to investigate the consistence of FIN with diff...
