Authors: Mane RS, Ghosh S, Singh S, Chopade BA, Dhavale DD.
Abstract: Anomeric 1,5-anhydrosugar 2 was synthesized from d-glucose derived N-Cbz protected aminodiol 8. The key step involves, acid catalyzed hydrolysis of 1,2-acetonide group in 8 to get hemiacetal that concomitantly undergoes formation of the pyranose ring by attack of C-3 hydroxyethyl group on anomeric C-1, leading to the formation of dioxabicyclo[3.2.1]octane skeleton which on hydrogenolyis gave 2. The glycosidase inhibitory activities of hydroxy- and amino-substituted anomeric 1,5-anhydrosugars 1 and 2, respectively, showed selective inhibition of α-mannosidase. These results were substantiated by molecular docking studies using WHAT IF software and AUTODOCK 4.0 program.
