Purpose: To study the inclusion mechanism and heat stability of the complex formed between 4'hydroxychalcone and hydroxypropyl-β-cyclodextrin (HP-β-CD) Methods: The inclusion mechanism of the complex of 4'-hydroxychalcone and HP-β-CD was investigated by phase solubility method. The physicochemical properties of the complex were evaluated by Fourier transform infrared spectroscopy (FT-IR) and x-...

Complexation with cyclodextrins (CDs) is a technique that has been extensively used to increase the aqueous solubility of oils and improve their stability. In addition, this technique has been used to convert oils into solid materials. This work aims to develop inclusion complexes of Copaifera multijuga oleoresin (CMO), which presents anti-inflammatory activity, with β-cyclodextrin (β-CD) and h...

The effects of native cyclodextrins (alpha, beta or gamma), hydroxypropyl-beta-cyclodextrin, beta-cyclodextrin solubilized in urea, soluble starch and glucose in water solution on the fluorescence behaviour of melatonin (N-acetyl-5-methoxytryptamine) (M) and 5-methoxytryptamine [5-methoxy-3-(2-aminoethyl)indole] (5M) were determined. In addition, the effect of methanol and propanol with and wit...

BACKGROUND Vorinostat (suberoylanilide hydroxamic acid) is the first histone deacetylase inhibitor approved by US FDA for use in oncology. However, as a hydrophobic acid, its limited aqueous solubility poses a problem for parenteral delivery. Such limited solubility may also affect its oral bioavailability. OBJECTIVE The aim of this study was to evaluate whether cyclodextrins (CDs), common ex...

Disulfiram (DS) has an excellent anti-viral activity; however, its low water-solubility and first-pass metabolism are limiting clinical applications. Cyclodextrins (CDs) have been used as solubility enhancers carriers of DS proposed for inhalation to treat SARS-CoV-19. Two types CDs (hydroxypropyl β-cyclodextrin sulfobutyl ether β-cyclodextrin) were form inclusion complexes wi...

The present study was undertaken to examine the effect of pH and concentration of hydroxypropyl-beta-cyclodextrin on the solubility of carvedilol as it shows pH-dependent solubility. The equilibrium solubility of carvedilol in a series of solutions of varying pH (from 1.2 to 11) was determined and compared with the equilibrium solubility of carvedilol in the presence of 20% hydroxypropyl-beta-c...

The knowledge of the host-guest complexes using cyclodextrins (CDs) has prompted an increase in the development of new formulations. The capacity of these organic host structures of including guest within their hydrophobic cavities, improves physicochemical properties of the guest. In the case of pesticides, several inclusion complexes with cyclodextrins have been reported. However, in order to...
