at pH 5 as compared to pH 7, which is generally considered as a good property for pharmacologicalchaperones. Surprisingly, most of the compounds strongly inhibited GCase in wild type fibroblasts at rather low concentrations, showing an unfavourable chaperone/inhibitor balance on disease-associated GCase mutants in cellulo. A structure–activity relationship analysis points to the need for keeping a contiguous
