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, Gaucher disease, and selective GBA1 inhibitors are sought after as potential chemical chaperones. The physiological
葡萄糖基神经酰胺合酶(GCS)是用于临床治疗溶酶体贮积症的重要药物,也是抗击2型糖尿病的有希望的药物。氨基糖是开发GCS抑制剂的有用线索。然而,据报道,有效的亚氨基糖型GCS抑制剂与其他糖加工酶具有不必要的交叉反应性。特别是,亚氨基糖型GCS抑制剂通常还会在一定程度上抑制人酸性葡糖神经酰胺酶(GBA1)和非溶酶体葡糖神经酰胺酶(GBA2),这两种酶均已知可处理葡糖神经酰胺。其中,GBA1本身是用于治疗溶酶体贮积病,高雪氏病的潜在药物靶标,并且选择性的GBA1抑制剂被寻求作为潜在的化学伴侣。关于疾病状态,GBA2在糖基神经酰胺加工中的生理重要性尚不十分清楚,在此,选择性抑制剂可以用作化学敲除实体。在本次交流中,我们报告了对高度有效和选择性的N-烷基化L-氨基构型亚氨基糖的鉴定。特别是,GCS对GBA1的选择性为27。
