Herein, we present an alternative and elegant synthetic approach toward powerful β-glucosidase inhibitor isofagomine. Derivatizations of the ring nitrogen provided a selected set of N-modified isofagomine analogues. Biological evaluation of these compounds showed a remarkable change in potency as well as α/β-preference for various glycosidases from different sources when compared to the parent compound isofagomine. Overall, the conducted N-modification improved the potency against α-glucosidase from Saccharomyces cerevisiae (GH13). Coming along, significant diminished activities toward GH1 family β-glucosidases from three different sources have been observed for all tested derivatives. Moreover, and contrary to isofagomine, deactivations of β-galactosidase from Escherichia coli (GH2) as well as α-mannosidase from Canavalia ensiformis (GH38) have not been verified for this series of compounds.
