Medchemexpress LLC Cholic acid 7-sulfate | 60320-05-0 | 99.9% | 25 MG
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 functions as a gut-restricted TGR5 agonist, binding to TGR5 on enteroendocrine L cells to induce GLP-1 secretion and improve glucose tolerance in a TGR5-dependent manner. Additionally, it acts as an endogenous ligand for MR1, promoting the survival of mucosal-associated invariant T cells (MAIT) and affecting MAIT cell development and function. This compound is primarily used in the research of diabetes and MAIT cell-related immune regulation.
