Cholic acid 7-sulfate is a selective agonist targeting TGR5 (EC50=0.17 μM) and a ligand for MHC class I-related protein (MR1). It acts as a gut-restricted TGR5 agonist, binding to TGR5 on enteroendocrine L cells, inducing GLP-1 secretion, and improving glucose tolerance in a TGR5-dependent manner. Additionally, it serves as an endogenous ligand for MR1, promoting the survival of mucosal-associated invariant T cells (MAIT) and the expression of homeostatic gene signatures, influencing MAIT cell development and function. It is primarily used in the research of diabetes and MAIT cell-related immune regulation.
