Background

GPBAR-A is an agonist of bile acid receptor GPBAR1 [1].

The G protein-coupled bile acid receptor 1 (GPBAR1, TGR5) is a plasma membrane-bound receptor for bile acids. TGR5 is involved in gallstone formation and is expressed in the epithelium of human gallbladders [2].

GPBAR-A is an agonist of bile acid receptor GPBAR1. In GLUTag cells, GPBAR-A stimulated glucagon-like peptide (GLP-1) release. In primary colonic cultures, GPBAR-A increased GLP-1 release by 4.2-fold. In upper small intestinal cultures, GPBAR-A increased GLP-1 release by 2.6-fold. In GLUTag cells, GPBAR-A increased cAMP concentration by 57%. Also, GPBAR-A increased calcium in 56/149 cells and caused the mean response by 1.3-fold. In the presence of glucose, GPBAR-A increased calcium in 148/149 cells and caused the mean response by 2.6-fold. In the presence of diazoxide (the KATP channel opener, 340 μM) and 70 mM KCl, GPBAR-A also increased GLP-1 secretion. In colonic and small intestinal cultures, GPBAR-A increased the GLP-1 secretion by 2.4-fold and 1.5-fold. The GLP-1 secretion mediated by GPBAR-A was independent on KATP channel closure [1].
