Cyclodextrins are a family of cyclic oligosaccharides composed of -(1,4) linked glucopyranose subunits. Cyclodextrins are useful molecular chelating agents. They possess a cage-like supramolecular structure, which is the same as the structures formed from cryptands, calixarenes, cyclophanes, spherands and crown ethers. These compounds having supramolecular structures carry out chemical reaction...

Columns containing different types of cyclodextrin derivatives have been evaluated for chiral gas chromatographic separation of atropisomeric PCBs, o,p9-DDT and o,p9-DDD. Separation was attempted on columns containing mixed chiral selectors, and the performance of two closely related selectors was also examined. The cyclodextrins were: permethylated-b-CD (PM-b-CD), heptakis(2,3-di-O-methyl-6O-t...

Determination of protein concentration is often an absolute prerequisite in preparing samples for biochemical and proteomic analyses. However, current protein assay methods are not compatible with both reducers and detergents, which are however present simultaneously in most denaturing extraction buffers used in proteomics and electrophoresis, and in particular in SDS electrophoresis. It was fo...

Inclusion complexation of drugs with cyclodextrins is evolved in the recent past as an important phenomenon to increase the solubility, stability, and bioavailability of drugs along with masking of other undesirable properties, thus making the drug candidate more palatable. Cyclodextrins are known to form non-covalent bonded inclusion complexes with variety of drugs in both solution and solid s...

The first syntheses of two cyclic tetramers of cyclodextrins, dubbed tetraplexes, are described as well as the use of one of them to form a supramolecular assembly with a modified biopolymer.

Self-assembly supramolecular nanoparticles (SNPs) are synthesized using polyethylenimine (PEI) crosslinked by cyclodextrins (CyDs), adamantyl doxorubicin and plasmid DNA. SNPs successfully conduct the cooperative co-delivery of chemotherapeutic anticancer drug and plasmid DNA in vitro and in vivo.

Fluorogenic supramolecular complexes formed between tubular-shaped pyrenyl-β-cyclodextrins and glyco-rhodamine are determined to respond to a selective lectin with 'turn-on' fluorescence with excellent selectivity over a range of competing species.

A series of methylated β-cyclodextrins (CDs) regioselectively leaving one or two hydroxy groups were prepared, and fluorescence spectroscopic measurements showed that they have unique binding characteristics against 2-p-toluidinylnaphthalene-6-sulfonate as a guest molecule in aqueous solution.
