Polymers containing cyclodextrins (CD) covalently or supramolecularly attached are of increasing interest in recent years. For example, polymers bearing β-CD as side or terminal groups and their interaction with classical guest groups such as adamantane or azo-dyes Cited by: 2. Cyclodextrins can interact with appropriately sized drug molecules to yield an inclusion complex. These noncovalent inclusion complexes offer a variety of advantages over the noncomplexed form of.

Thorbjørn Terndrup Nielsen, Véronique Wintgens, Catherine Amiel, Reinhard Wimmer and Kim Lambertsen by: Cyclodextrins, since their discovery in the late 19th century, were mainly regarded as excipients. Nevertheless, developments in cyclodextrin research have shown that some of these hosts can capture and include biomolecules, highlighting fatty acids and cholesterol, which implies that they are not inert and that their action may be used in specific medicinal g: poly book.

Herein, we present an endeavor toward exploring the lacuna underlying the host:guest chemistry of inclusion complex formation between bile salt(s) and β-cyclodextrin(s) (βCDs). An extensive thermodynamic investigation based on isothermal titration calorimetry (ITC) demonstrates a dominant contribution from exothermic enthalpy change (ΔH Cited by: In addition, cyclodextrins can for example be used to reduce gastrointestinal drug irritation, convert liquid drugs into microcrystalline or amorphous powder, and prevent drug-drug and drug-excipient interactions.

Actually, cyclodextrins are among the most remarkable macrocyclic molecules with major theoretical and practical interest for chemistry and biology. Cyclodextrins belong to the family of cage molecules due to their structure, which is composed of a hydrophobic cavity that Cited by: 6.

In addition, cyclodextrins can be used to reduce or prevent gastrointestinal and ocular irritation, reduce or eliminate unpleasant smells or tastes, prevent drug-drug or drug-additive interactions, or to convert oils and liquid drugs into microcrystalline or amorphous powders.

The main feature of cyclodextrins is the ability to encapsulate lipophilic compounds, and thus many applications have been developped in various by: 1. In case of cyclodextrin-based supramolecular complexes, the cyclic molecule is natural cyclodextrins and the polymers are PVA, PEG, PTA, PBA, PPG, and so forth; moreover, when the guest moiety (drug) is attached covalently to a host molecule (cyclodextrin) in a suitable way, an intra/intermolecular complex is obtained from supramolecular Cited by: Macromolecular Recognition by Polymer‐Carrying Cyclodextrins: Interaction of a Polymer Bearing Cyclodextrin Moieties with Poly(acrylamide)s Bearing Aromatic Side Chains † Akihito Hashidzume Department of Macromolecular Science, Graduate School of Science, Osaka University, Toyonaka, Osaka ‐, JapanCited by:   In the past 30 years, much attention has been directed to construction of supramolecular structures using some intermolecular interactions, such as hydrogen bonding, electrostatic interactions, and metal-ligand interactions.

In this chapter, construction of supramolecular polymers using cyclodextrins is described. α-,β- and γ-Cyclodextrins have been shown to exist as aggregates in solution bound together by a network of hydrogen bonds.

Removal of this network by ionisation of the hydroxyl groups leads to a greatly increased solubility and removal of aggregation. The presence of aggregates in solution of structure breaking solutes in which the solubility ofβ-cyclodextrin is greatly enhanced, leads to Cited by: The interactions of cyclodextrins (CDs) with poly(N-acryloyl-amino acids) (pAXaa) were investigated by 1H NMR and two dimensional nuclear Overhauser effect spectroscopy (2D NOESY) to elucidate the.

Steroids are abundant in living organisms and are responsible for various biological functions. They are good candidates for inclusion complexes formation with cyclodextrins; therefore, plenty of literature describes these complexes and their application in various fields.
