본 발명은 면역질환을 효과적으로 예방 및 치료할 수 있는 바이구아나이드(biguanide) 유도체 화합물에 관한 것이다. 본 발명의 바이구아나이드계 유도체 화합물은 염증성 사이토카인인 IL-17 및 TNF-α의 생성을 억제시키며, 면역조절 기능을 갖는 조절 T 세포의 활성을 증대시킬 뿐만 아니라, 면역질환 동물모델에 대해 우수한 치료 효과를 나타낸다. 따라서 각종 면역반응의 조절 이상으로 유발되는 자가면역질환, 염증성질환 및 이식거부질환과 같은 면역질환을 예방 또는 치료할 수 있는 약학적 조성물 또는 면역 억제제로 유용하게 사용될 수 있다.
Abstract:
The present invention relates to a composition for preventing or treating inflammatory bowel diseases comprising metformin as an active ingredient. A metformin compound or a composite of the metformin and etanercept (product name: Enbrel) have an excellent effect in maintaining the thickness of small intestines and the length of large intestines in a state similar to a normal state, an excellent effect in controlling or reducing the activity of IL-17 and TNF-a, and an excellent effect in promoting or increasing the activity of IFNr, thereby able to be practically used as a pharmaceutical composition for preventing or treating autoimmune diseases including the treatment of inflammatory bowel diseases.
Abstract:
The present invention relates to a composition for preventing or treating immune diseases by suppressing B cell activities which are induced by metformin and, more specifically, to a composition for preventing or treating immune diseases, which includes a metformin compound or pharmaceutically acceptable salts thereof. The composition suppresses or reduces activities of etiological B cells. According to the present invention, the composition for preventing or treating immune diseases can be used as an immune suppressor by suppressing or reducing the etiological B cells in various autoimmune diseases, suppressing or reducing activities of etiological Th17 cells, and promoting or increasing activities of regulatory T cells (Treg).
Abstract:
The present invention relates to a composition for preventing or treating obesity or metabolic diseases which includes Grim19 protein as an active ingredient and, specifically, to a composition for preventing or treating obesity or metabolic diseases including Grim19 protein as an active ingredient which can prevent or treat metabolic diseases caused by immune response disorder or interactions of genetically, metabolically, and environmentally complex factors. The Grim 19 proteins according to the present invention, fat cell reduction effects and total in vivo cholesterol amount are enhanced, suppression of differentiation of cytotoxic Th17 cells which produce and secrete inflammatory cytokine is enhanced, and effects of controlling inflammatory environment related to obesity using STAT3 as a mediator by the Grim19 so that the Grim 19 proteins can be used for manufacturing medicines and functional foods which can effectively treat obesity or lipid related metabolic diseases.
Abstract:
본발명은건선또는피부경화증을포함하는피부질환을효과적으로치료할수 있는조성물에관한것으로, 구체적으로메트포민을유효성분으로포함하는피부질환예방또는치료용약학조성물에관한것이다. 본발명에따른메트포민을포함하는조성물은홍반, 각질, 표피두께를감소시키고, 염증성사이토카인인 IL-17, IL-6 및 STAT3의발현을억제시킴으로써피부표피조직의손상을완화시키고결과적으로건선을효과적으로치료할수 있다. 또한, 상기조성물은섬유증의활성을억제시키고, 염증성사이토카인인 IL-6 및 STAT3의발현과 Th17 세포의발현을억제시키며, 섬유화의대표전사인자인 COLI1a 및 TGF-β유전자의발현을억제함으로써피부경화증을효과적으로치료할수 있다.
