AM-1638 is a potent and orally bioavailable GPR40/FFA1 full agonist with an EC50 of 0.16 μM. AM-1638 exhibits moderate cross-species plasma clearance and volume of distribution, resulting in plasma half-lives suitable for evaluation of its antidiabetic properties in mouse, rat, and cynomologus monkey. AM-1638 exhibits antidiabetic activity in BDF/DIO mice. Moreover, oral administration of full agonist AM-1638 demonstrates excellent oral bioavailability (mouse, >100%; rat, 72%; and cyno, 71%).

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.
