Inhibitory effects of alpha-cyclodextrin and its derivative against sucrose-induced hyperglycemia in an in vivo evaluation system.
Ishii M, Matsumoto Y, Sekimizu K
Cyclodextrins (CyDs) are cyclic oligosaccharides consisting of six to eight glucose residues. Administration of ?-CyD (six glucose residues) inhibits sucrose-induced hyperglycemia in humans. Here we show that oral administration of ?-CyD and dimethyl ?-CyD suppresses sucrose-induced hyperglycemia in an in vivo evaluation system using silkworms. On the other hand, ?-CyD (seven glucose residues), ?-CyD (eight glucose residues), and their derivatives did not show the suppressive effect. These findings suggest that dimethyl ?-CyD is a new inhibitor against sucrose-induced hyperglycemia and the silkworm system is useful for evaluation of suppressive activities of ?-CyD derivatives against postprandial hyperglycemia.
