in Gaucher disease. We demonstrate that established β-glucoside-configured cyclophellitol-type activity-basedprobes (ABPs) for GBA also are effective, mechanism-based, and irreversible inhibitors of EGCII. The stability of EGCII is markedly enhanced by formation of covalent complexes with cyclophellitol ABPs substituted with hydrophobic moieties, as evidenced by an increased melting temperature, resistance

The natural product, cyclophellitol and its aziridine analogue are potent mechanism-based retaining β-glucosidase inhibitors. In this paper we explore the inhibitory potency of a number of cyclophellitol analogues against the three human retaining β-glucosidases, GBA, GBA2 and GBA3. We demonstrate that N-alkyl cyclophellitolaziridine is at least equally potent in inhibiting the enzymes evaluated as

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

An activity based probe (ABP) comprising a glycosidase inhibitor, and a detection-group. The ABPs of the inventions are used for diagnosing storage disorder for screening of compounds suitable for preventing and/or treating a storage disorder, for monitoring of therapeutic enzymes for lysosomal storage disorders, and for ultra-sensitive visualization of glycosidase-fusion proteins in molecular imaging.

configurational and functional isomers are powerful covalent inhibitors of retaining glycosidases, and find application in fundamental studies on glycosidases, amongst others in relation to inherited lysosomal storage disorders caused by glycosidase malfunctioning. Few direct and stereoselective aziridination methodologies are known for the synthesis of cyclophellitol aziridines. Herein, we present our studies
