Abstract

Novel macrocyclic sugar clusters, which are constructed with a macrocyclic skeleton and four carbohydrate branches composed of glucose, maltose, or maltotriose derivatives individually, were prepared. Host-guest interactions between the hosts and a fluorescent guest, 8-anilinonaphthalene-1-sulphonate, were examined in aqueous media. The sugar clusters having maltose, or maltotriose residues strongly bind concanavaline A, but never peanut lectin. Novel macrocyclic sugar clusters having glucose, maltose, and maltotriose derivatives individually were prepared. The guest-binding behavior of the sugar clusters toward hydrophobic guest was examined by fluorescence spectroscopy in aqueous media. [Display omitted]
