The present invention concerns D-deoxygalactonojirimycin derivatives shown below. These compounds display an increased inhibitory potency towards GCS, and/or an increased inhibitory potency towards GBA2, and/or a decreased inhibitory potency towards GBA1, relative to known deoxynojirimycin derivatives of the same D-galactoconfiguration. Therefore, compounds of the present invention are effective in the treatment of diseases which are associated with an irregular level of cytosolic or lysosomal glucosylceramide and/or higher glycosphingolipids, such as a lysosomal storage disorder, such as Gaucher disease, Fabry disease, Tay-Sachs disease, Sandhoff disease, GM1 gangliosidosis, Sialidosis, Niemann Pick disease type C and AMRF, or a symptom of one of the diseases collectively classed as metabolic syndrome, such as obesity, insulin resistance, hyperlipidemia, hypercholesterolemia, polycystic kidney disease, type II diabetes and chronic inflammation, or a neurodenegerative disorder, such as Parkinson disease or Lewy-body dementia.
本发明涉及如下所示的 D-脱氧半
乳糖苷irimycin衍
生物。与已知的具有相同
D-半乳糖构型的脱氧半乳尻霉素衍
生物相比,这些化合物对 GCS 的抑制效力增强,和/或对 GBA2 的抑制效力增强,和/或对 GBA1 的抑制效力减弱。因此,本发明的化合物可有效治疗与细胞膜或溶酶体
葡萄糖甘油酰胺和/或高级糖
磷脂水平不正常有关的疾病,如溶酶体贮积症,如戈谢病、法布里病、泰-萨克斯病、桑霍夫病、GM1
神经节苷脂病、Sialidosis、Niemann 病等、
胰岛素抵抗、高脂血症、高
胆固醇血症、多囊肾、II 型糖尿病和慢性炎症等疾病的症状,或帕
金森病或路易体痴呆等神经系统疾病的症状。
