Electrospinning has been used to successfully create polystyrene (PS) nanofibers containing either of three different types of cyclodextrin (CD); α-CD, β-CD, and γ-CD. These three CDs are chosen because they have different sized cavities that potentially allow for selective inclusion complex (IC) formation with molecules of different size or differences in affinity of IC formation with one type...

MUC1 is an oncoprotein that is overexpressed in up to 90% of breast carcinomas. A previous in vitro study by our group demonstrated that the cytoplasmic domain of MUC1 (MUC1-CD), the minimal functional unit of MUC1, contributes to the malignant phenotype in cells by binding directly to β-catenin and protecting β-catenin from GSK3β-induced degradation. To understand the in vivo role of MUC1-CD i...

The aim of this study was to evaluate hot-melt extrusion (HME) as a continuous process to form cyclodextrin (CD) inclusion complexes in order to increase the solubility and dissolution rate of itraconazole (ITZ), a class II model drug molecule of the Biopharmaceutics Classification System. Different CD derivatives were tested in a 1:1 (CD:ITZ) molar ratio to obtain CD ternary inclusion complexe...

We report that three-component systems comprising styryl dyes (1 or 2) and two hosts (hydroxypropyl-β-cyclodextrin (HP-β-CD) and cucurbit[7]uril (CB[7])) undergo photoinduced transformation and translocation of the styryl guest from the cavity of HP-β-CD to CB[7]. We find that the protonation of guest trans-1 or the addition of Ba(2+) as competitor for CB[7] triggers dissociation of the contain...

Supramolecular materials with noncovalent bonds have attracted much attention due to their exclusive properties differentiating them from materials formed solely by covalent bonds. Especially interesting are rotor molecules of topological complexes that shuttle along a polymer chain. The shuttling of these molecules should greatly improve the tension strength. Our research employs cyclodextrin ...

This study was carried out to find a cholesterol removal rate, flavor development and bitter amino acid productions in Cheddar cheese treated with β-cyclodextrin (CD): 1) Control (no homogenization, no β-CD), and 2) Milk treatment (1000 psi milk homogenization, 1% β-CD). The cholesterol removal of the cheese was 79.3%. The production of short-chain free fatty acids (FFA) increased with a ripeni...

The cyclodextrin glucosyltransferase enzyme (CGTase) is an industrially crucial for the production of β-cyclodextrin (β-CD). CGTase has a high propensity to produce mixture cyclodextrins (CDs). From industrial perspective, that produces only one type CD critical importance. Bacillus sp. PBS1 produced converts starch solely into β-CD. isolated strain was found close similarity with alkaliphilic ...

Ferrocenylnaphthalene diimide carrying β-cyclodextrin (β-CD), 1, intercalated into double-stranded DNA with a binding affinity of K = (6.6 ± 0.8) × 10(4) M(-1) and a binding site size of n = 4, with a high positive cooperative parameter of ω = 14. β-CD and ferrocene moieties of the compound contributed to the formation of the intermolecular inclusion complex on DNA. Binding of 1 resulted in con...

Cyclodextrins (CDs) are conical molecules with a hydrophilic surface and hydrophobic cavity. Thanks to the cavity, CDs able form inclusion complexes wide variety of guest molecules. A new oil-in-water (O/W) emulsifying system suitable for use in preparing Pickering emulsions large range oils was developed. This contains β-Cyclodextrin (β-CD) natural origin selected surfactant, Polyglyceryl-3 di...
