Glycine-β-muricholic acid (GβMCA) is an intestine-selective antagonist of the farnesoid X receptor (FXR) and the glycine-conjugated form of the murine-specific primary bile acid β-muricholic acid (Item No. 20287).1,2 It inhibits expression of the FXR target genes Shp and Fgf15 induced by the FXR ligands chenodeoxycholic acid (Item No. 10011286) and GW 4064 (Item No. 10006611) in Caco-2 cells when used at a concentration of 100 μM. GβMCA is resistant to hydrolysis by fecal bile salt hydrolase (BSH) isolated from gut microbiota, indicating gut stability. Dietary administration of GβMCA (10 mg/kg) decreases Shp and Fgf15 mRNA expression in ileum, but not liver, and reduces ceramide levels and expression of the ceramide synthesis-related genes Sptlc2, Sptlc3, Cers2, Cers4, Degs1, Degs2, Smpd3, and Smpd4 in ileum of mice with high-fat diet-induced obesity and db/db mice. It also prevents weight gain, reduces blood glucose levels, and increases insulin sensitivity as well as prevents development of cholestasis and necrotic lesions in liver of mice with high-fat diet-induced obesity.
