Benzenesulfonamidoquinolino-beta-cyclodextrin as a cell-impermeable fluorescent sensor for Zn2+.

Abstract

A water-soluble benzenesulfonamidoquinolino-beta-cyclodextrin has been successfully synthesized in 30% yield by incorporating a N-(8-quinolyl)-p-aminobenzenesulfonamide (HQAS) group to beta-cyclodextrin through a flexible linker. This compound exhibits a good fluorescence response in the presence of Zn2+ in water but gives poor fluorescence responses with… (More)
