Abstract:
The present invention relates to a novel indole derivative or a pharmaceutically allowable salt thereof, a preparation method thereof, and a pharmaceutical composition for preventing or treating dyslipidemia containing the same as an active ingredient. The novel indole derivative according to the present invention combines a niacin GPR109A receptor, activates the receptor, and induces less activation of beta-arrestin signal transduction pathway, thereby minimizing a facial blushing side effect and being used as a composition for preventing, alleviating, or treating dyslipidemia such as hyperlipemia, hypercholesterinemia, hypertriglyceridemia, etc.
Abstract:
The present invention relates to a pharmaceutical composition for preventing or treating cancers or Temodal-resistant glioblastoma, containing azathioprine as an active ingredient. The azathioprine according to the present invention effectively suppresses the proliferation of glioblastoma, which is a kind of brain tumor, and exhibits an excellent therapeutic effect even on glioblastoma cancer cells having resistance to Temodal (temozolomide), which is an existing agent for treating glioblastoma. Therefore, the azathioprine according to the present invention can be useful as an active ingredient of a pharmaceutical composition for preventing or treating cancers such as brain tumors (especially, glioblastoma) and Temodal-resistant glioblastoma.

Abstract:
The present invention relates to 4-(benzimidazole-2-ylamino)pyrrolidine derivatives of chemical formula 1 or pharmaceutically acceptable salts thereof; a pharmaceutical composition containing the same as an active ingredient for preventing and treating neurodegenerative diseases; and an inhibitor composition of the activation of beta-secretase (BACE), containing the same as an active ingredient. The 4-(benzimidazole-2-ylamino)pyrrolidine derivatives according to the present invention suppresses the activation of BACE and generation of beta-amyloid proteins which cause damage to nerve cells, thereby effectively preventing or treating neurodegenerative diseases such as Alzheimer’s disease and Down syndrome.
Abstract:
PURPOSE: A pyrazole butyl compound and a pharmaceutical composition containing the same are provided to ensure dopamine D4 receptor affinity and to prevent and treat central nervous system diseases. CONSTITUTION: A pyrazole butyl compound and pharmaceutically acceptable salt thereof are denoted by chemical formula 1. The salt includes inorganic acid salt, organic acid salt, amino acid salt, alkali metal salt, or ammonium salt. A method for preparing the pyrazole butyl compounds comprises: a step of performing reductive amination of pyrazole aldehyde compound of chemical formula 2 with heterocycle compounds of chemical formula 3 under the presence of reducing agent and base. A pharmaceutical composition for treating central nervous system diseases contains 1-(4-chlorophenyl)-4-(4-(1-phenyl-3-propyl-1H-pyrazole-5-yl)butyl)piperazine(compound No. 33) or 1-(4-(1-phenyl-3-propyl-1H-pyrazole-5-yl)butyl)-4-(3-(trifluoromethyl)phenyl)piperazine(compound No. 36).
Abstract:
PURPOSE: A pharmaceutical composition containing a novel 3-(methoxymethyl)pyrazole derivative is provided to ensure dopamine D3 and D4 receptor affinity and to suppress psychotic behavior(cage climbing) in a mouse. CONSTITUTION: A novel 3-(methoxymethyl)pyrazole derivative is denoted by chemical formula 1. The compound of chemical formula 1 is prepared by reductive amination of pyrazole aldehyde derivative of chemical formula 2 with piperazine derivative of chemical formula 3 under the presence of reductant and base. A pharmaceutical composition for treating central nervous system diseases contains the compound of chemical formula 1.
