The present invention relates to a use of a novel compound, for preventing, improving or treating amyotrophic lateral sclerosis (ALS). The present inventors have found that SOD1 aggregation is one of the important causes of ALS, and have proposed the possibility that WT-SOD1 aggregation, caused by suppressing the regulation of intracellular stress or TDP-43, may be a cause of sALS. In addition, the present inventors have discovered the novel compound PRG-A-01(SLC-B036) as a SOD1 aggregation and misfolding inhibitor. The compound exhibited a protective effect against muscle weakness and movement disorder in an ALS mouse model. According to the result of a histological analysis, intraspinal nerves were maintained by means of a treatment using PRG-A-01(SLC-B036). In addition, the present inventors have obtained a candidate compound (PRG-A-04) which can be a more optimized drug. Consequently, the compound of the present invention may be usefully employed in developing a therapeutic agent for ALS.
本发明涉及一种新化合物的用途,用于预防、改善或治疗肌萎缩侧索硬化症(ALS)。本发明人发现SOD1聚集是ALS的重要原因之一,并提出通过抑制细胞内应激或TDP-43的调节可能导致WT-SOD1聚集,可能是sALS的原因之一。此外,本发明人发现了新化合物PRG-A-01(SLC-B036)作为SOD1聚集和错误折叠抑制剂。该化合物在ALS小鼠模型中表现出对肌肉无力和运动障碍的保护作用。根据组织学分析的结果,通过使用PRG-A-01(SLC-B036)治疗,脊髓神经得以维持。此外,本发明人还获得了一种候选化合物(PRG-A-04),可作为更优化的药物。因此,本发明的化合物可用于开发治疗ALS的治疗剂。
