| In Vitro | In vitro activity: GSK1292263 is a novel, potent GPR119 agonist, which showed potential for the treatment of type 2 diabetes. It is currently undergoing phase 2 clinical trial for type 2 diabetes. GSK1292263 improves glucose regulation in animal models of diabetes, but has no effect on plasma glucose in type 2 diabetics. 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.
Kinase Assay: GSK-1292263 is selected from 1538 compounds by using Hypo1, the Fit-Value and Estimate of GSK-1292263 that is aligned in Hypo1 are 8.8 and 7.7 (nM), respectively
Cell Assay: 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 Vivo | GSK-1292263 administrated at a single dose of 3-30 mg/kg in the absence of nutrients correlates with increased levels of circulating gastrointestinal peptides, including glucagon-like peptide 1 (GLP-1), gastric inhibitory polypeptide (GIP), peptide YY (PYY) and glucagon in male Sprague-Dawley rats, the increase is enhanced following administration of glucose in the oral glucose tolerance test (OGTT). GSK-129226 significant increases in the peak insulin response and insulin AUC(0-15 min) of 30-60% compared with values in the vehicle control cohort in the intravenous glucose tolerance test in rats, this insulin upregulation correlated with a significant increase in the glucose disposal rate. GSK-1292263 is associated with a statistically significant increase in insulin immunoreactivity in pancreatic sections in a 6-week study performed in Zucker diabetic fatty rats, compared with insulin immunoreactivity in samples obtained from rats receiving vehicle control. GSK-1292263 administrated at dose of 10 or 30 mg/kg or vehicle control at 2 hours prior to insulin infusion in hyperinsulinemic-euglycemic clamps stimulates glucagon secretion without increasing blood glucose levels Sprague-Dawley rats. |
