Patent number: 11969397Abstract: The present invention relates to a composition for preventing or treating transplantation rejection or a transplantation rejection disease, comprising a novel compound and a calcineurin inhibitor. A co-administration of the present invention 1) reduces the activity of pathogenic Th1 cells or Th17 cells, 2) increases the activity of Treg cells, 3) has an inhibitory effect against side effects, such as tissue damage, occurring in the sole administration thereof, 4) inhibits various pathogenic pathways, 5) inhibits the cell death of inflammatory cells, and 6) increases the activity of mitochondria, in an in vivo or in vitro allogenic model, a transplantation rejection disease model, a skin transplantation model, and a liver-transplanted patient, and thus inhibits transplantation rejection along with mitigating side effects possibly occurring in the administration of a conventional immunosuppressant alone.Type: GrantFiled: November 7, 2019Date of Patent: April 30, 2024Assignee: THE CATHOLIC UNIVERSITY OF KOREA INDUSTRY-ACADEMIC COOPERATION FOUNDATIONInventors: Mi-La Cho, Dong-Yun Shin, Jong-Young Choi, Chul-Woo Yang, Sung-Hwan Park, Seon-Yeong Lee, Min-Jung Park, Joo-Yeon Jhun, Se-Young Kim, Hyeon-Beom Seo, Jae-Yoon Ryu, Keun-Hyung Cho
