GPR40, one of the G protein-coupled receptors predominantly expressed in pancreatic β-cells, mediates enhancement of glucose-stimulated insulin secretion by free fatty acids. A potent and selective GPR40 agonist is theorized to be a safe and effective antidiabetic drug with little or no risk of hypoglycemia. Cyclization of the phenylpropanoic acid moiety of(More)
G protein-coupled receptor 40 (GPR40)/free fatty acid receptor 1 (FFA1) is a free fatty acid (FFA) receptor that mediates FFA-amplified glucose-stimulated insulin secretion in pancreatic β-cells. We previously identified (2,3-dihydro-1-benzofuran-3-yl)acetic acid derivative 2 as a candidate, but it had relatively high lipophilicity. Adding a polar(More)
Object tracking is a highly difficult process to implement on a single sensor chip especially for complex real-world targets. This paper shows that the advanced BMA (Block Matching Algorithm), which can track vehicles in the real world, has been implemented on a single chip using CMOS sensor technology. The device incorporates 64 APS (Active Pixel Sensor),(More)
The discovery of a novel series of β-methyltryptophan (β MeTrp) derivatives as selective and orally active non-peptide somatostatin receptor 2 (SSTR2) agonists for the treatment of Type 2 diabetes is described. In our previous research, Compound A, β-MeTrp derivative with highly potent and selective SSTR2 agonistic activity IC50 (SSTR2/SSTR5)=0.3/>100 (nM),(More)
