  • Publication number: 20250064778
    Abstract: The present invention relates to granules comprising Progerinin, capsules or sachets using same, and a preparation method therefor. More specifically, in order to develop a formulation that is advantageous when applying, to patients, Progerinin, which is a poorly water-soluble drug having a Hutchinson-Gilford progeria treatment effect, Progerinin granules comprising a specific water-soluble polymer, solubility enhancer and excipient at an optimum composition ratio have been developed and oral solid preparations such as capsules or sachets have been developed using the granules, such that dispersion stability and bioavailability of Progerinin can be improved and storage, transport and patient drug compliance can also be improved.

  • Publication number: 20240092741
    Abstract: The present invention relates to a composition for prevention or treatment of neurofibromatosis type 2 syndrome, wherein in contrast to the conventional T?R1 kinase inhibitor TEW7197, the compound represented by chemical formula 1, a pharmaceutically acceptable salt thereof, a solvate thereof, a stereoisomer thereof, or a combination thereof according to the present invention suppresses TGF-? receptor 1 (T?R1)-mediated RKIP reduction while not inhibiting normal TGF-? signaling and thus, can be used as a novel form of a therapeutic agent for neurofibromatosis type 2 syndrome, which can solve the side effect problem caused by the inhibition of normal TGF-? signaling.

  • Publication number: 20230063754
    Abstract: The present invention relates to a novel method for synthesizing a decursin derivative, the method comprising: a step (I) for preparing a solution by mixing cinnamyl bromide and an N-Methyl-2-pyrrolidone [N-Methyl-2-pyrrolidone (NMP)] solvent; a step (II) for preparing a solution by mixing decursinol, a tetrahydrofuran (THF) solvent, and sodium hydride (NaH); and a step (III) for obtaining a decursin derivative by mixing the solutions prepared in step (I) and step (II). The method can increase the yield of the obtained decursin derivative compound and enables mass production.

  • Publication number: 20220402930
    Abstract: 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.
