The formation of host-guest complexes between surfactants and cyclodextrins.

Advances in colloid and interface science

Valente AJ, Söderman O.
PMID: 24011696
Adv Colloid Interface Sci. 2014 Mar;205:156-76. doi: 10.1016/j.cis.2013.08.001. Epub 2013 Aug 12.

Cyclodextrins are able to act as host molecules in supramolecular chemistry with applications ranging from pharmaceutics to detergency. Among guest molecules surfactants play an important role with both fundamental and practical applications. The formation of cyclodextrin/surfactant host-guest compounds leads...

Environmental gas sensing needs stringent sensor requirements in terms of sensitivity, selectivity and ruggedness. One of the major issues to be addressed is combining in a single device the conflicting requirements of molecular-level selectivity and low-ppb sensitivity. The exploitation...

Optimized methods for preparation of 6(I)-(ω-sulfanyl-alkylene-sulfanyl)-β-cyclodextrin derivatives.

The understanding of supramolecular recognition in room-temperature ionic liquids (RTILs) is key to develop the full potential of these materials. In this work, we provide insights into the selectivity of the binding of alkali metal cations by standard cyclodextrin...

Inclusion of trans-resveratrol in methylated cyclodextrins: synthesis and solid-state structures.

Beilstein journal of organic chemistry

Trollope L, Cruickshank DL, Noonan T, Bourne SA, Sorrenti M, Catenacci L, Caira MR.
PMID: 25670983
Beilstein J Org Chem. 2014 Dec 29;10:3136-51. doi: 10.3762/bjoc.10.331. eCollection 2014.

The phytoalexin trans-resveratrol, 5-[(1E)-2-(4-hydroxyphenyl)ethenyl]-1,3-benzenediol, is a well-known, potent antioxidant having a variety of possible biomedical applications. However, its adverse physicochemical properties (low stability, poor aqueous solubility) limit such applications and its inclusion in cyclodextrins (CDs) has potential for addressing...
