This study aimed to improve the production of β-cyclodextrin (β-CD) by microbial cells immobilized on synthetic or loofa sponges both with and without the use of alginate or chitosan. The most suitable matrix for the immobilization of Bacillus firmus strain 7B was synthetic sponge and for Bacillus sphaericus strain 41 was loofa sponge. After 330 days of storage, the β-CD production by Bacillus ...

On-off switching and molecular logic in fluorescent molecules are associated with what chemical inputs can do to the structure and dynamics of these molecules. Herein, we report the structure of a naphthalene derivative, the fashion of its binding to β-cyclodextrin and DNA, and the operation of logic possible using protons, cyclodextrin, and DNA as chemical inputs. The compound crystallizes out...

A new and efficient synthesis of benzoxanthene drivatives from the three-component condensation reaction ofaryl aldehydes and β-naphthol under solvent-free conditions in the presence of β-cyclodextrin sulfonic acid, as an efficient heterogeneous solid acid catalyst with excellent yields and short reaction time is presented

The cyclical structure of this molecule has been previously employed in various industries: In low fat dairy spreads, hydrophobic cholesterol is removed using a process by lodging it inside the cyclodextrin. Hydroxypropyl-β-cyclodextrin (HPβCD) is the principle active compound in the fabric odour eliminator Febreze, the cyclodextrin simply envelops any malodorous molecules leaving even my runni...

The setting time of ternesite-calcium sulfoaluminate (TCSA) is shorter while the fluidity and mechanical strength are lower. Herein, method synergistic regulation polycarboxylate superplasticizer β-cyclodextrin was adopted to solve this. results showed that, compared reference sample, when 0.25% compounded with 0.05% β-cyclodextrin, TCSA prolonged, increased by 118% (201 mm). And net pastes com...

Polycyclic aromatic hydrocarbons (PAHs) are the byproducts of the incomplete combustion of carbon-based fuels, and have high affinity towards DNA strands, ultimately exerting their carcinogenic effects. They are ubiquitousenvironmental contaminants,and can accumulate on tissues due to their lipophilic nature. In this article, we describe a novel concept for PAH removal from aqueous solutions us...

In this paper the procedure for the preparation of inclusion compounds of bioactive substance 2-[(2-aminoetoxy)-methyl]-4-(2-chlorophenyl)-1,4-dihydro-6-methyl-3,5-pyridine dicarboxylic acid 3-ethyl-5-methyl esterbenzene sulfonate, called amlodipine besylate with β-cyclodextrin (β-CD) and their structural characterization was described. Molecular inclusion compound of amlodipine besylate is obt...

A first report on the fabrication of nanocomposite scaffolds containing nano-hydroxyapatite/carboxymethyl chitosan/β-cyclodextrin heterojunctions fused with date seed extract for bone tissue engineering applications.

The objectives of this study were to characterize a synthesis brom-isoflavanone (notated IF) with possible pharmacological activities, water insoluble and to examine the potential of beta-cyclodextrin to improve this property and obtain inclusion compounds that were analysed by different techniques: UV-Vis, IR, 1HNMR spectroscopy, thermal analysis. The presence of β-cyclodextrin rises the conte...

Batch synthesis of sulphobutyl ether β-cyclodextrin (also known as SBE-β-CD or SBECD) is a process effectively divided into three main stages, i.e. initial reagent dissolution, a sulphoalkylation reaction and final reaction quenching. This reaction is followed by downstream processing and purification, and ultimate isolation of the solid SBECD material. However, a feature associated with using ...
