Background

AS 1269574,(2-[2-(4-bromophenyl)-6-methylpyrimidin-4-yl] amino ethanol), was capable of inducing glucose-stimulated insulin secretion (GSIS) and improved glucose tolerance in normal mice. AS 1269574 is an agonist of GPR119 with EC50 value of 2.5 µM [1] [2].
GPR119 is highly expressed in pancreatic β-cells. This receptor enhances the effect of GSIS via the elevation of intracellular cAMP concentrations [2].
Treated with either 1 or 10 µM AS 1269574 for 20 min, the insulin secretion of mouse pancreatic MIN-6 β-cells pre-exposed to 16.8 mM glucose was significantly increased compared with the DMSO vehicle control. In contrast, AS 1269574 did not affect the insulin release of MIN-6 cells previously treated with low-glucose (2.8 mM) [2].
In normal mice, a single treatment with 100 mg/kg of AS 1269574 significantly reduced the area under the curve (AUC) after 2 h (AUC0-2h) of blood glucose. AS 1269574 significantly increase the plasma insulin AUC0-2h in mice compared with the vehicle control. A single oral administration of 100 mg/kg AS 1269574 did not significantly lower the blood glucose AUC in either fasted or fed mice, indicating AS 1269574 did not have a hypoglycemic effect [2].
