Abstract

In this study, we designed and prepared two new β-cyclodextrins (1 and 2) bearing ethylene glycol chains to develop highly water-soluble cyclodextrins. They had excellent water solubility and could successfully dissolve 17-β-estradiol in water, which was considered a poorly soluble drug model. Additionally, the nuclear magnetic resonance structural analysis of a mixed sample of 17-β-estradiol and 1 in D₂O–H₂O suggested two different types of inclusion complexes with different 17-β-estradiol molecule orientations inside the cavity of 1.

期刊介绍： The Journal of Inclusion Phenomena and Macrocyclic Chemistry is the premier interdisciplinary publication reporting on original research into all aspects of host-guest systems. Examples of specific areas of interest are: the preparation and characterization of new hosts and new host-guest systems, especially those involving macrocyclic ligands; crystallographic, spectroscopic, thermodynamic and theoretical studies; applications in chromatography and inclusion polymerization; enzyme modelling; molecular recognition and catalysis by inclusion compounds; intercalates in biological and non-biological systems, cyclodextrin complexes and their applications in the agriculture, flavoring, food and pharmaceutical industries; synthesis, characterization and applications of zeolites. The journal publishes primarily reports of original research and preliminary communications, provided the latter represent a significant advance in the understanding of inclusion science. Critical reviews dealing with recent advances in the field are a periodic feature of the journal.
