Abstract: The present invention relates to a crystalline form of (E)-methyl 6-((3S,8S,9S,10R,13S,14S,17R)-3-(((5S,6R)-5-acetoxy-6-(acetoxytnethyl)-5,6-dihydro-2H-pyran-2-yl)oxy)-10,13-dimethyl-2,3,4,7,8,9,10.11,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthrene-17-yl)hept-5-enoate and a blood vessel leak blocker comprising the same. The novel crystalline form has high purity, excellent stability, excellent long-term storage and pharmaceutical stability, and can be used as a vascular leakage blocker, so it is very advantageous in producing high-quality drug substances.

Abstract: The present invention relates to an enteric coating tablet comprising: a core containing, as an active ingredient, dimethyl fumarate or a pharmaceutically acceptable salt thereof; and an enteric coating layer, and provides a tablet, which exhibits an effect equal to that of a capsule dosage form currently on the market, can be prepared through a simple preparation process, and is a dosage form having excellent storage stability and administration convenience, and thus can be applied to various patient groups.

Abstract: The pharmaceutical composition according to the present invention contains the active ingredient dimethyl fumarate or monomethyl fumarate or a pharmaceutically acceptable salt thereof in a specific dose, and exhibits specific pharmacokinetic parameters when administered into the body. In addition, the pharmaceutical composition of the present invention has proven its efficacy and safety in type 2 diabetic nephropathy patients with albuminuria, and thus can be effectively used as a preventive or therapeutic agent for diabetic nephropathy.

Abstract: The present invention relates to a preparation method of a novel vascular leakage blocker with a high yield. The preparation method is easy to react and more productive and economical than the conventional method by using an intermediate that can easily remove impurities generated during the reaction. In addition, the preparation method can produce a novel vascular leakage blocker with a high yield by using a new reagent that has not been previously used in the step of generating an isomer, and is very advantageous in producing a high-quality active pharmaceutical ingredient.

Abstract: The present invention relates to a novel tryptophan hydroxylase inhibitor and a pharmaceutical composition including same, wherein the novel tryptophan hydroxylase inhibitor has an excellent inhibitory effect on TPH1, and thus can be usefully used for the prevention or treatment of disorders, such as metabolic disorders, cancer, digestive or cardiovascular system disorders, related to TPH1 activity. In particular, the novel tryptophan hydroxylase inhibitor has an excellent treatment effect on inflammatory bowel disorders, and thus can be usefully used for the treatment of inflammatory bowel disorder.

Abstract: The present invention relates to an enteric coating tablet comprising: a core containing, as an active ingredient, dimethyl fumarate or a pharmaceutically acceptable salt thereof; and an enteric coating layer, and provides a tablet, which exhibits an effect equal to that of a capsule dosage form currently on the market, can be prepared through a simple preparation process, and is a dosage form having excellent storage stability and administration convenience, and thus can be applied to various patient groups.

Abstract: The present invention provides a decoy peptide or polypeptide capable of inhibiting the binding of AMIGO2 and 3-phosphoinositide-dependent kinase 1 (PDK1), and a pharmaceutical composition, containing the decoy peptide or polypeptide as an active ingredient, for preventing or treating cancer or an angiogenic disease. Furthermore, the present invention provides a method for screening a material for preventing or treating cancer or an angiogenic disease. According to the present invention, it is worth noting that the decoy peptide or polypeptide of the present invention induces apoptosis through the inhibition of the binding of AMIGO2 and 3-phosphoinositide-dependent kinase 1 (PDK1); reduces migration and adhesion of endothelial cells; significantly reduces vascular induction, survival, and growth.
