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

iminosugar type GCS inhibitors often also inhibit to some extent human acid glucosylceramidase (GBA1) and the nonlysosomal glucosylceramidase (GBA2), the two enzymes known to process glucosylceramide. Of these, GBA1 itself is a potential drug target for the treatment of the lysosomal storage disorder, Gaucherdisease, and selective GBA1 inhibitors are sought after as potential chemical chaperones. The physiological
A highly regioselectivereductivecleavage of the bis-benzylidene acetal of d-mannitol was performed using a BF3·Et2O/Et3SiH reagent system. A chiral intermediate 6 thus obtained was efficiently utilized in the stereoselective synthesis of the anticancer agent OGT2378 (3) and glycosidase inhibitor derivative N-tosyl 1,4-dideoxy-1,4-imino-l-xylitol (22).
