The molecularly imprinted polymer (MIP) based on methacrylic acid functionalized β-cyclodextrin (MAA-β-CD) monomer was synthesized for the purpose of selective recognition of benzylparaben (BzP). The MAA-β-CD monomer was produced by bridging a methacrylic acid (MAA) and β-cyclodextrin (β-CD) using toluene-2,4-diisocyanate (TDI) by reacting the -OH group of MAA and one of the primary -OH groups ...

Fluconazole was studied with two different hydrophilic cyclodextrins (hydroxypropyl-β-cyclodextrin (HPBCD) and sulfobutyl ether-β-cyclodextrin (SBECD)) for the formation of inclusion complexes. HPBCD and SBECD showed low cell cytotoxicity in human keratocytes as assessed by the label-free xCELLigence system for real-time monitoring. The fluconazole-HPBCD complex was incorporated into an ion-sen...

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...

Poor aqueous solubility of anticancer drug, albendazole (ABZ), prevents parenteral application. Here, we demonstrate how to increase the aqueous solubility of ABZ to 6- 8 mg/ml using sulfobutylether - β-cyclodextrin (SBE-β-CD) or Hydroxypropyl- β-cyclodextrin (HP- β-CD) by manipulation of complexation parameters such as the physical state of ABZ (ionized in acetic acid), the concentration of io...

The influence of oligosaccharides (α-cyclodextrin, β-cyclodextrin and γ-cyclodextrin), a polysaccharide, sodium hyaluronate (NaHy), on the diffusion aqueous solutions cobalt chromium chlorides has been investigated. Cobalt are constituents metal alloys for biomedical use, including dental prostheses. Thus, release these ions in human body can lead to harmful biological effects. interaction with...

In this research, we report on the synthesis of mesoporous silicas with various quantities of immobilized oligosaccharide groups and different pore ordering degree. The hydrothermal co-condensation of tetraethyl orthosilicate and β-cyclodextrin-containing organosilane in the presence of cetyltrimethylammonium bromide template was employed. The purpose of this investigation was to show the oppor...

The influence of organic additives, β-cyclodextrin, HEDTA, L-aspartic acid and L-glutamic acid on crystal growth of calcium carbonate via vapour diffusion method has been investigated. In the absence of additive, regular rhombohedral calcium carbonate crystal habit resulted. Whereas in presence of additive, calcite with truncated, aggregated rhombohedral sub crystals and elongated hexagonal mor...

The advanced water treatment taken by organic micro-pollution or microbiological pollution resource has been a hot issue of public concern. In this article, novel quaternary ammonium salt functionalized β-cyclodextrin polyurethane (QAS-β-CDPU) microparticles were successfully constructed for above-mentioned pollutants removal. By adjusting the proportion chlorine-containing monomers, we studied...

An anhydrous 1:1 crystalline inclusion complex between the organophosphorus insecticide fenitrothion [O,O-dimethyl O-(3-methyl-4-nitrophenyl)phosphorothioate] and the host compound heptakis(2,6-di-O-methyl)-β-cyclodextrin (DIMEB) was prepared and its structure elucidated by single-crystal X-ray diffraction. This revealed two independent host molecules in the asymmetric unit. In one of these, th...

Encapsulation makes the difference!. A β-cyclodextrin-based diphosphane ligand with metal confining properties is key in stabilization of heteroleptic Cu(I) complexes. In their Research Article (e202214638), Nicola Armaroli, Béatrice Delavaux-Nicot, Jean-François Nierengarten, Dominique Armspach et al. show how encapsulation metal-bound diimine moiety cyclodextrin cavity influences electronic p...
