The present invention relates to novel α-keto carbonyl calpain inhibitors for the treatment of neurodegenerative diseases and neuromuscular diseases including Duchenne Muscular Dystrophy, Becker Muscular Dystrophy and other muscular dystrophies. Disuse atrophy and general muscle wasting can also be treated. Generally all conditions where elevated levels of calpains are involved can be treated. The compounds of the invention may also inhibit other thiol proteases such as cathepsin B, cathepsin H, cathepsin L, papain or the like. Multicatalytic Protease (MCP) also known as proteasome may also be inhibited. The compounds of the present invention are also inhibitors of cell damage by oxidative stress through free radicals and can be used to treat mitochondrial disorders and neurodegenerative diseases, where elevated levels of oxidative stress are involved.
本发明涉及用于治疗神经退行性疾病和神经肌肉疾病,包括杜兴氏肌肉萎缩症、贝克氏肌肉萎缩症和其他肌肉萎缩症的新型α-酮羰基卡尔宁
抑制剂。也可以治疗运动不足性萎缩和一般肌肉消耗。通常,所有涉及卡尔宁升高
水平的情况都可以得到治疗。本发明的化合物还可以抑制其他
硫醇
蛋白酶,如卡
特普辛B、卡
特普辛H、卡
特普辛L、
木瓜蛋白酶等。多催化
蛋白酶(MCP),也称为
蛋白酶体,也可以被抑制。本发明的化合物还是通过自由基抑制氧化应激引起的细胞损伤的
抑制剂,并可用于治疗涉及氧化应激升高
水平的线粒体疾病和神经退行性疾病。
