Conduritol B Epoxide

Conduritol B epoxide (CBE) is an irreversible inhibitor of glucocerebrosidase, also known as acid β-glucosidase, glucosylceramidase, GBA, or GBA1 (IC₅₀ = 9 μM). Inhibition of this lysosomal glucosidase results in the accumulation of glucocerebroside without affecting cell viability, lysosomal enzyme release, or the activity of intracellular enzymes. It also does not inhibit non-lysosomal glucosylceramidase or cytosolic β-glucosidase.
