The present invention relates to a novel compound capable of effectively preventing and treating immune diseases and a use thereof. The novel compound of the present invention has effects of inhibiting the production of inflammatory cytokines, increasing the activity of regulatory T cells having immune regulatory functions, inhibiting the production of auto-antibodies to regulate excessive immune responses, and inhibiting the differentiation of osteoclasts, and thus can be used for treating immune diseases, such as autoimmune disease, inflammatory disease, and transplant rejection diseases, which are caused by abnormal regulation of various kinds of immune responses.Linvention concerne un nouveau composé permettant de prévenir et de traiter efficacement des maladies immunitaires, ainsi que lutilisation de ce composé. Le nouveau composé selon linvention présente des effets dinhibition de la production de cytokines inflammatoires, daugmentation de lactivité de lymphocytes T régulateurs dotés de fonctions immunorégulatrices, dinhibition de la production dauto-anticorps pour réguler les réactions immunitaires excessives, et dinhibition de la différenciation dostéoclastes. Ce composé peut ainsi être utilisé dans le traitement des maladies immunitaires, telles quune maladie auto-immune, une maladie inflammatoire et les maladies de rejet du greffon, qui sont provoquées par une régulation anormale de divers types de réactions immunitaires.본 발명은 면역질환을 효과적으로 예방 및 치료할 수 있는 신규 화합물 및 이의 용도에 관한 것이다. 본 발명의 신규 화합물은 염증성 사이토카인의 생성을 억제시키며, 면역조절 기능을 갖는 조절 T 세포의 활성을 증대시킬 뿐만 아니라, 자가 항체 생산을 억제하여 과도한 면역반응을 제어할 수 있으며 파골세포의 분화를 억제할 수 있는 효과가 있어, 각종 면역반응의 조절 이상으로 유발되는 자가면역질환, 염증성질환 및 이식거부질환과 같은 면역질환 치료를 위한 용도로 사용될 수 있는 효과가 있다.
