Abstact

Competitive inhibitors of galactocerebrosidase (GALC) could be candidates for pharmacological chaperone therapy of patients with Krabbe disease. The known and selective nortropane-type iminosugar galacto-noeurostegine has been found to competitively inhibit GALC with K i = 7 μM at pH 4.6, which is 330-fold more potent than the analogous deoxynoeurostegine. It was shown through X-ray protein crystallography that galacto-noeurostegine binds to the active site of GALC in its bicyclic form.
