  • Publication number: 20240131027
    Abstract: The present invention relates to a pharmaceutical composition comprising a novel compound as an active ingredient for prevention or treatment of transplant rejection. The novel compound SD911 of the present invention was identified to repress the migration of immune cells, increase the engraftment and viability of a grafted tissue, and regulate immune cells. In addition, it was found in a kidney transplantation model that the compound restrained human PBMC from suppressing the engraftment and damaging renal tissues and downregulated the expression of the inflammatory cytokine IL-17, with the consequent effective prevention and treatment of transplant rejection.
