Since their discovery, cyclodextrins have widely been used as green and easily available alternatives to promoters or catalysts of different chemical reactions in water. This review covers the research and application of cyclodextrins and their derivatives in asymmetric and stereospecific syntheses, with their division into three main groups: (1) cyclodextrins promoting asymmetric and stereospe...

Cyclodextrin glycosyltransferase (CGTase) (EC 2.4.1.19) is used for the industrial production of cyclodextrins. Its application, however, is hampered by the limited cyclodextrin product specificity and the strong inhibitory effect of cyclodextrins on CGTase activity. Recent structural studies have identified Arg47 in the Bacillus circulans strain 251 CGTase as an active-site residue interacting...

Collagen and cyclodextrins are well known as triple helical protein and oligosaccharides. Cyclodextrins are the simplest organic compounds, which exhibit complex formation with other organic molecules and hence are excellent models of enzymes. This property of cyclodextrins to form inclusion complexes is being exploited in the present investigation. In fibrillogenesis, collagens with intact tel...

The numerous hydroxyl groups available in cyclodextrins are active sites that can form different types of linkages. They can be crosslinked with one another, or they can be derivatized to produce monomers that can form linear or branched networks. Moreover, they can form inclusion complexes with polymers and different substrates, modifying their physicochemical properties. This review shows the...

The present review discusses the use of cyclodextrins and their derivatives to prepare electrospun nanofibers with specific features. Cyclodextrins, owing unique capability form inclusion complexes hydrophobic volatile molecules, can indeed facilitate encapsulation bioactive compounds in allowing fast-dissolving products for food, biomedical, pharmaceutical purposes, filtering materials wastewa...

Cyclodextrins are used to improve stability of flavor and/or oil via encapsulation of certain specific ingredients that exist by nature in food materials. The method is called often as “molecular encapsulation”, because the ingredients are encapsulated in the molecular cavity of cyclodextrins. Cyclodextrins form inclusion complexes with a variety of molecules including flavors, fats and colors....

Cyclodextrins are cyclic (α -1, 4)-linked oligosaccharides of α -D-glucopyranose containing a relatively hydrophobic central cavity and hydrophilic outer surface. Cyclodextrins, which can serve as solubilising and stabilizing agent of drug, are very significant in improving the bioavailability of drug, increasing the solubility, decreasing the stimulation, and masking the Smell. The objective o...

The high effectiveness of cyclic oligosaccharides like cyclodextrins in the production of trans-resveratrol in Vitis vinifera cell cultures is enhanced in the presence of methyl jasmonate. In order to dissect the basis of the interactions among the elicitation responses triggered by these two compounds, a transcriptional analysis of grapevine cell cultures treated with cyclodextrins and methyl ...

The utility of phosphated α-, β- and γ-cyclodextrins as water-soluble chiral NMR solvating agents for cationic substrates is described. Two sets of phosphated cyclodextrins, one with degrees of substitution in the 2-6 range, the other with degrees of substitution in the 6-10 range, are examined. Results with 33 water-soluble cationic substrates are reported. We also explored the possibility tha...
