A glucose selective diphenylboronic acid fluorescent sensor (10a) vith a K-a of 1472 M-1 has been synthesized and evaluated. This sensor shoals a 43- and 49-fold selectivity for glucose over fructose and galactose, respectively. The binding affinity improvement is about 300-fold and the selectivity. improvement for glucose over fructose is about 1400-fold compared vith the monoboronic acid compound. phenylboronic acid. H-1 NMR studies indicate that sensor 10a binds with alpha-D-glucofuranose in a bidentate manner (1:1 ratio). (C) 2002 Elsevier Science Ltd. All rights reserved.
