Biological Activity
gsk1292263 is a novel agonist of gpr119 receptor agonist and is used for the treatment of type 2 diabetes.gpr119 is described as a class a (rhodopsin-type) orphan gpcr with no close primary sequence relative in the human genome. the activation of gpr119 increases the intracellular accumulation of camp, resulting in enhanced insulin secretion from pancreatic β-cells and increased release of the gut peptides glp-1 (glucagon-like peptide 1), gip (glucose-dependent insulinotropic peptide) and pyy (polypeptide yy).in vitro, gsk1292263 treatment displayed little inhibition towards cyps (cyp1a2, 2c9, 2c19, 2d6, 3a4), p-gp, oatp1b3, or oct2. however, gsk1292263 inhibited bcrp and oatp1b1, which are transporters involved in statin disposition 1.in the glucose tolerance test in rats, administration of gsk-1292263 significantly increases the peak insulin response and insulin auc (0-15 min) as compared with the values in the vehicle control. the upregulation of insulin was found to correlate with an increase in the glucose disposal rate. in hyperinsulinemic-euglycemic clamps, gsk-1292263 administration on sprague-dawley rats at dose of 10 or 30 mg/kg 2 hours prior to insulin infusion can promote glucagon secretion with no increase of blood glucose levels 2.
