GW-1100 Chemical Structure

GW 1100 is a selective antagonist of GPR40-mediated Ca2+ elevations in HEK293 cells stimulated by GW 9508 (an agonist of both GPR40 and GPR120, another GPCR activated by long chain fatty acids) or linoleic acid with a pIC50 value equal to 5.99.

Abstract
1. Long chain fatty acids have recently been identified as agonists for the G protein-coupled receptors GPR40 and GPR120. Here, we present the first description of GW9508, a small-molecule agonist of the fatty acid receptors GPR40 and GPR120. In addition, we also describe the pharmacology of GW1100, a selective GPR40 antagonist. These molecules were used to further investigate the role of GPR40 in glucose-stimulated insulin secretion in the MIN6 mouse pancreatic beta-cell line. 2. GW9508 and linoleic acid both stimulated intracellular Ca2+ mobilization in human embryonic kidney (HEK)293 cells expressing GPR40 (pEC50 values of 7.32+/-0.03 and 5.65+/-0.06, respectively) or GPR120 (pEC50 values of 5.46+/-0.09 and 5.89+/-0.04, respectively), but not in the parent HEK-293 cell line. 3. GW1100 dose dependently inhibited GPR40-mediated Ca2+ elevations stimulated by GW9508 and linoleic acid (pIC50 values of 5.99+/-0.03 and 5.99+/-0.06, respectively). GW1100 had no effect on the GPR120-mediated stimulation of intracellular Ca2+ release produced by either GW9508 or linoleic acid. 4. GW9508 dose dependently potentiated glucose-stimulated insulin secretion in MIN6 cells, but not in primary rat or mouse islets. Furthermore, GW9508 was able to potentiate the KCl-mediated increase in insulin secretion in MIN6 cells. The effects of GW9508 on insulin secretion were reversed by GW1100, while linoleic acid-stimulated insulin secretion was partially attenuated by GW1100. 5. These results add further evidence to a link between GPR40 and the ability of fatty acids to acutely potentiate insulin secretion and demonstrate that small-molecule GPR40 agonists are glucose-sensitive insulin secretagogues.

Abstract
GW1100 is an antagonist of GPR40 identified by high throughput screening recently. The synthesis of GW1100 has been developed. The key step involves cyclization of the 2-thiouracil heterocycle under acidic condition at room temperature.

Abstract
In cells lacking expression of Ca(2+)-mobilizing G proteins, coexpression of human GPR40 and Galpha(q) allowed medium- and long-chain fatty acids to elevate intracellular [Ca(2+)]. This was also observed when human embryonic kidney (HEK) 293 cells were transfected with a GPR40-Galpha(q) fusion protein. The kinetic of elevation of intracellular [Ca(2+)] slowed with increasing fatty acid chain length, suggesting different ligand on-rates, whereas the addition of fatty acid-free bovine serum albumin reduced signals, presumably by binding the fatty acids. To allow effective ligand equilibration, GPR40-Galpha(q) was used in guanosine 5'-O-(3-[(35)S]thio)triphosphate ([(35)S]GTPgammaS) binding assays. After expression of GPR40-Galpha(q) in HEK293 cells and membrane preparation basal binding of [(35)S]GTPgammaSinGalpha(q) immunoprecipitates was high and not elevated substantially by fatty acids. ...
