assessed on GBA2 selectivity offset against the other glucosylceramide metabolizing enzymes, glucosylceramide synthase (GCS), lysosomal glucosylceramidase (GBA), and the cytosolic retaining β-glucosidase, GBA3. Our work, yielding potent and selective GBA2 inhibitors, also provides a roadmap for the development of high-throughput assays for identifying retaining glycosidase inhibitors by FluoPol-ABPP

A syntheticroute for the preparation of glucosylceramide synthase inhibitor N-[5-(adamantan-1-yl-methoxy)-pentyl]-1-deoxynojirimycin methanesulfonic acid salt (AMP-DNM) has been developed. Herein we report the development and optimization of this syntheticroute from its initial version in an academic research laboratory at milligram-scale to the final optimized route that was implemented in a cGMP

In this article, we present a straightforward synthesis of adamantan-1-yl-methoxy-functionalized 1-deoxynojirimycin derivatives. The used synthetic routes are flexible and can be used to create a wide variety of lipophilic mono- and difunctionalized 1-deoxynojirimycin derivatives. The compounds reported here are lipophilic iminosugar based on lead compound 4, a potent inhibitor of the three enzymes

This work details the evaluation of a number of N-alkylated deoxynojirimycin derivatives on their merits as dual glucosylceramide synthase/neutral glucosylceramidase inhibitors. Building on our previous work, we synthesized a series of d-gluco and l-ido-configured iminosugars N-modified with a variety of hydrophobic functional groups. We found that iminosugars featuring N-pentyloxymethylaryl substituents are considerably more potent inhibitors of glucosylceramide synthase than their aliphatic counterparts. In a next optimization round, we explored a series of biphenyl-substituted iminosugars of both configurations (d-gluco and l-ido) with the aim to introduce structural features known to confer metabolic stability to drug-like molecules. From these series, two sets of molecules emerge as lead series for further profiling. Biphenyl-substituted l-ido-configured deoxynojirimycin derivatives are selective for glucosylceramidase and the nonlysosomal glucosylceramidase, and we consider these as leads for the treatment of neuropathological lysosomal storage disorders. Their d-gluco-counterparts are also potent inhibitors of intestinal glycosidases, and because of this characteristic, we regard these as the prime candidates for type 2 diabetes therapeutics.

The present invention discloses a therapeutic target for the treatment of cystic fibrosis. It was found that inhibition of non-lysosomal glucosylceramidase (GBA2) sufficiently restores chloride current in cells from CF patients carrying the common delF508-CFTR mutation. With the catalytic centre (4) of the enzyme positioned on top of the membrane bilayer face particularly potent inhibitors are found in deoxynojirimycin derivatives having a group that is capable of inserting in the membrane bilayer.
