GSK137647A is a selective FFAR4 (GRP120) agonist for human, Mouse and Rat FFA4 with pEC50 values of 6.3, 6.2 and 6.1, respectively. GSK137647A is shown to provide at least 100-fold selectivity against the panel which included 41 G-protein-coupled receptors. Under high glucose conditions (25 mM), GSK137647A produces a concentration-dependent increase in glucose stimulated insulin secretion. GSK137647A induces insulin secretion and inhibits epithelial ion transport, GSK137647A is related to regulation of glucose homeostasis and anti-inflammatory response. GSK137647A has anti-inflammatory activity.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 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 Compound A of 10 mg/kg.
