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...

Recently a great interest in the field of protein engineering and the design of innovative drug delivery systems employing specific ligands such as cyclodextrins is observed. The paper reports the solid state, thermal method for protein coupling with β-cyclodextrin and the physicochemical and biological properties of the obtained conjugates. The structure of the obtained conjugates was investig...

Bacillus licheniformis RM44 was isolated from hot spring near Karachi and screened forthe production of extracellular amylase Amy RM44. Amy RM44 was purified to homogeneityon a single step by affinity chromatography using insoluble corn starch. The molecular weightof Amy RM44 was estimated to be 66 kDa by SDS–PAGE and zymographic analysis. Nine foldpurification was achieved with the specific ac...

Pioglitazone is an anti-diabetic drug in high blood sugar in patients with type 2 diabetes (non-insulin-dependent diabetes) which was belongs to poor aqueous solubility and bioavailable drug. By using β Cyclodextrin, the solubility and dissolution rate of Pioglitazone HCL can be enhanced and it was evaluated by synthesizing it into solid inclusion complexes in different ratio of drug: β cyclode...

The aim of this study was to design orally disintegrating tablets of Olanzapine and to complex Olanzapine with 2-hydroxypropyl-β- cyclodextrin with special emphasis on disintegration and dissolution studies. Phase solubility studies demonstrated the formation of 1:1 molar inclusion complex by kneading method. Tablets were prepared by using superdisintegrants namely, sodium starch glycolate, cro...

This study aimed to examine the effects of α-cyclodextrin and β-cyclodextrin as stabilizing agents on gold nanoparticles (AuNPs) reduced by o-hydroxybenzoic acid. Comparative studies were carried compare size AuNPs after addition agents. The optimization was done under agent concentration. with optimum at 0.040 M agent. DLS analysis showed that agents, decreased. result indicated AuNPs, added h...

Supramolecular property systems composed of alkyltrimethylammonium surfactants and β-cyclodextrin were studied by means of a chemical probe. Solvolysis of 4-methoxybenzenesulfonyl chloride (MBSC) was used in the mixed systems with the aim of being able to determine the concentration of uncomplexed cyclodextrin in equilibrium with the micellar system. The surfactants used enabled us to vary the ...

An innovative and versatile strategy of Solid Phase Microextraction (SPME) is shown by using a new type of β-cyclodextrin-modified nanocellulose (CD-NC) as a sorbent material. β-cyclodextrin (used as an inclusion-type selector) was covalently bonded to amine-modified nanocellulose by an amidation reaction. Such novel nanocavities were successfully applied to the selective recognition of danoflo...
