Biological Activity

GW9508 is a selective FFA1/GPR40 agonist (pEC50 values are 7.32, < 4.3 and < 4.3 for FFA1, FFA2 and FFA3 receptors respectively). GPR40 was formerly an orphan G protein-coupled receptor whose endogenous ligands have now been identified as free fatty acids (FFAs). GW9508 showed greater than 500-fold selectivity for GPR40 over GPR41 and GPR43 and possessed a good in vitro and in vivo profile with excellent bioavailability. GW9508 inhibited CCL17 and CCL5 expression in a pertussis toxin-sensitive manner. GW9508 also inhibited CCL5 and CXCL10 production by normal human epidermal keratinocytes. Administration of GW9508 topically to the skin in the challenging phase suppressed ear swelling in a repeated hapten application model and contact hypersensitivity with downregulation of CCL5 and CXCL10, respectively. 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.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
