Competitive inhibitors of galactocerebrosidase (GALC) could be candidates for pharmacological chaperone therapy of patients with Krabbe disease. The known and selective nortropane-type iminosugar -noeurostegine has been found to competitively inhibit GALC with = 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 -noeurostegine binds to the active site of GALC in its bicyclic form.
半乳糖脑苷脂酶（GALC）的竞争性抑制剂可能是用于克拉伯病患者药理伴侣疗法的候选药物。已发现已知的选择性降托烷型亚氨基糖——神经鞘氨醇在pH 4.6时以Ki = 7 μM的浓度竞争性抑制GALC，其效力比类似的脱氧神经鞘氨醇高330倍。通过X射线蛋白质晶体学表明，神经鞘氨醇以其二环形式结合到GALC的活性位点。
