USE OF NOVEL COMPOUND, FOR PREVENTING, IMPROVING OR TREATING AMYOTROPHIC LATERAL SCLEROSIS
06.05.2021
PCT/KR2020/015014 / PRG S&TECH INC.
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.
