Influence of β-Cyclodextrin Methylation on Host-Guest Complex Stability: A Theoretical Study of Intra- and Intermolecular Interactions as Well as Host Dimer Formation
(2023)
Understanding the non-covalent interactions in host-guest complexes is crucial to their stability, design and applications. Here, we use density functional theory to compare the ability of β-cyclodextrin (β-CD) and ...
Binding of Sulfamethazine to β-cyclodextrin and Methyl-β-cyclodextrin
(Springer, 2013-04)
β-cyclodextrin (βCD) and methyl-β-cyclodextrin (MβCD) complexes with sulfamethazine (SMT) were prepared and characterized by different experimental techniques, and the effects of βCD and MβCD on drug solubility were assessed ...
Direct short-wave photolysis of chlorpyrifos-methyl and chlorpyrifos-methyl oxon in the presence of cyclodextrins
(Springer, 2021-04)
Direct short-wave photolysis of chlorpyrifos-methyl (1) and chlorpyrifos-methyl oxon (2) was studied in the presence of native cyclodextrins (α–, β– and γ–CD) and randomly methylated β–CD (RAMEB). We used for irradiation ...
Improvement of galangin solubility using native and derivative cyclodextrins. An UV-Vis and NMR study
(2009)
The slightly water-soluble flavonoid galangin (G) and its inclusion with either β-cyclodextrin (βCD), hydroxypropyl-β-cyclodextrin (HPβCD) or Heptakis-2,6-O-di methyl-β-cyclodextrin (DMβCD) were investigated. The stoichiometric ...
Ethylenediaminetetraacetic acid (EDTA) as an auxiliary tool in the electrospray ionization mass spectrometry analysis of native and derivatized β-cyclodextrins, maltoses, and fructans contaminated with Ca and/or Mg
(Elsevier Science Inc, 2010-09)
The effect of Ca2+ (and Mg2+) and the disodium salt of ethylenediaminetetraacetic acid (EDTA), a well known Ca2+ (and Mg2+) chelating agent, on the volatilization/ionization of carbohydrates by using electrospray ionization ...
Amino β-cyclodextrins immobilized on gold surfaces: Effect of substituents on host-guest interactions
(Elsevier Ltd, 2018)
In the present paper we describe a simple method to immobilize amino cyclodextrins (CDs) and methylated-amino cyclodextrins on gold surfaces. We also report on the effect that the presence of methyl groups in the broader ...
NMR and molecular fluorescence spectroscopic study of the structure and thermodynamic parameters of EGCG/β-cyclodextrin inclusion complexes with potential antioxidant activity
(2014)
The present study is focused on the characterization of the interaction between (-)-epigallocatechingallate (EGCG) and cyclodextrins like β-cyclodextrin (βCD), heptakis(2,6 di-O-methyl)-β-cyclodextrin (DMβCD), and ...
13C and 15N solid-state NMR studies on albendazole and cyclodextrin albendazole complexes
(Elsevier, 2015-01)
13C and 15N solid-state nuclear magnetic resonance (NMR) spectra were recorded from albendazole (ABZ) and from ABZ:β-cyclodextrin, ABZ:methyl-β-cyclodextrin, ABZ:hydroxypropyl-β-cyclodextrin and ABZ:citrate-β-cyclodextrin, ...
Diloxanide furoate binary complexes with β-, methyl-β-, and hydroxypropyl-β-cyclodextrins: inclusion mode, characterization in solution and in solid state and in vitro dissolution studies
(Taylor, 2018-08)
The purpose of this study was to investigate the effect on solubility and dissolution rate of binary complexes of b -( b CD), methyl-(M b CD) and hydroxypropyl- b -cyclodextrin (HP b CD) with diloxanide furoate (DF).The ...
Reactivity of the insecticide chlorpyrifos-methyl toward hydroxy! and perhydroxyl ion. Effect of cyclodextrins
(John Wiley & Sons Ltd, 2009-07)
The reactivity of Chlorpyrifos-Methyl (1) toward hydroxyl ion and the α-nucleophile, perhydroxyl ion was investigated in aqueous basic media. The hydrolysis of 1 was studied at 25° C in water containing 10% ACN or 7% ...
