Gaucher disease is caused by inherited deficiency in glucocerebrosidase (GBA, a retaining beta-glucosidase), and deficiency in GBA constitutes the largest known genetic risk factor for Parkinson's disease. In the past, animal models of Gaucher disease have been generated by treatment with the mechanism-based GBA inhibitors, conduritol B epoxide (CBE), and cyclophellitol. Both compounds, however, also target other retaining glycosidases, rendering generation and interpretation of such chemical knockout models complicated. Here we demonstrate that cyclophellitol derivatives carrying a bulky hydrophobic substituent at C8 are potent and selective GBA inhibitors and that an unambiguous Gaucher animal model can be readily generated by treatment of zebrafish with these.

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.

epoxides and aziridines are potent and selective irreversible inhibitors of retaining glycosidases. We have previously reported on our studies on the use of activity-based probes derived from cyclophellitol and from its aziridine analogue for activity-based profiling of retaining -glucosidases in vitro, in situ, and in some examples also in vivo. In this work we disclose full details of the synthesis, purification
