In vitro: GPR120-IN-1 is fully selective for Gpr120 (logEC50=?7.62) with negligible activity towards Gpr40. GPR120-IN-1 produces concentration dependent increases in IP3 production from both human and mouse Gpr120 expressing cells. GPR120-IN-1 leads to a concentration-dependent response to recruit β-arrestin-2 in both human and mouse Gpr120 expressing cells, with EC50s of ~0.35 μM. GPR120-IN-1 strongly and comparably inhibits LPS-induced phosphorylation of Tak1, Ikkβ, and Jnk and blocked IκB degradation. In vivo: GPR120-IN-1 causes improved insulin sensitivity with increased glucose infusion rates, enhanced insulin stimulated-glucose disposal rate, along with a marked increase in the ability of insulin to suppress hepatic glucose production only in WT mice. GPR120-IN-1 treatment has beneficial effects on hepatic lipid metabolism, causing decreased hepatic steatosis, decreased liver triglycerides, and DAGs, along with reduced saturated free fatty acid conten.
|Animal models||Male C57Bl/6 WT or Gpr120 KO rats|
|Dosages||30 mg / kg|
|Body Surface Area (m2)||0.007||0.025||0.15||0.05||0.02||0.5|
|Animal A (mg/kg) = Animal B (mg/kg) multiplied by||Animal B Km|
|Animal A Km|
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.
