The aim of this study was to evaluate the antidegenerative effect in osteoarthritis damage of eriocitrin alone and eriocitrin formulated as innovative "dietary flavonoid supplement." A complexation between eriocitrin and hydroxypropyl β-cyclodextrin by solubilization/freeze-drying method was performed. The complex in solution was evaluated by phase solubility studies and the optimal 1 : 2 flava...

Gold particles are modified with surface-attached bis(beta-cyclodextrin)s bearing S-S bridges to give water-soluble cyclodextrin-modified gold nanoparticles, which are successfully used as recycling extractors for [60]fullerene.

A click chemistry approach based on the reaction between alkynylflavins and mono(6-azido-6-deoxy)-β-cyclodextrin has proven to be a useful tool for the synthesis of flavin-cyclodextrin conjugates studied as monooxygenase mimics in enantioselective sulfoxidations.

Article history: Received on: 26/07/2015 Revised on: 15/08/2015 Accepted on: 09/09/2015 Available online: 27/09/2015 Objective To evaluate the effect of Polyethylene glycol and β-cyclodextrin on the solubility and dissolution of silymarin, a poorly water soluble herbal drug. Methodology Effects of beta cyclodextrins and Polyethylene glycol on solubility of silymarin were evaluated by phase solu...

BACKGROUND This study evaluated the dose-response effects of alpha-cyclodextrin, a cyclic oligosaccharide, on the glycaemic and insulinaemic responses to the consumption of a standard carbohydrate meal. METHODS In a double-blind, randomised, cross-over design, 10 healthy subjects consumed boiled white rice containing 50 g of digestible carbohydrate to which 0 (control), 2, 5 or 10 g of alpha-...

The most common stoichiometry of drug/cyclodextrin complexes is 1:1, i.e. one drug molecule forms a complex with one cyclodextrin molecule, and the most common method for stoichiometric determination during formulation studies is the phase-solubility method. However, in recent years it has becoming increasingly clear that solubilizing effects of cyclodextrins are frequently due to the formation...

Values of binary mutual diffusion (interdiffusion) coefficients, obtained by using the Taylor dispersion method, for aqueous solutions of γ-cyclodextrin in the concentration range from (0.002 to 0.010) mol ·dm and temperatures (298.15 and 310.15) K are reported. From these experimental results, the hydrodynamic radius values for the γ-cyclodextrin are estimated. Also, the measured diffusion coe...

0 Post-treatment data were collected on a patient who received intravenous hydroxypropyl P-cyclodextrin in a dose of 1.5 g/kg in 1985. Although no untoward effects were observed in this patient, rarely occurring agitation and pulmonary edema have been noted after injections into rabbits and dogs, respectively. These complications are analyzed here on the basis of symptoms and on the effects of ...
