  GPBAR-A is a GPBA receptor (TGR5) agonist.

• Biologische Aktivität

  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].
