A small set of N-bridged 1-deoxynojirimycin dimers has been synthesized and evaluated as potential inhibitors of insect trehalase from midge larvae of Chironomus riparius, porcine trehalase as the mammalian counterpart and α-amylase from human saliva. All the tested compounds (2-4) proved to be active (micromolar range activity) against insect trehalase, showing selectivity toward the insect glycosidase. No activity was observed against α-amylase.
Keywords: Deoxynojirimycin; Enzyme inhibitors; Iminosugars; Trehalase; Trehalose.
