MK 0677 is a high affinity ghrelin receptor agonist (pKi = 8.14). Growth hormone (GH) secretagog; stimulates GH release from rat pituitary cells in vitro (EC50 = 1.3 nM) and enhances GH plasma levels in vivo. Also attenuates isoproterenol-induced lipolysis in rat adipocytes in vitro. Orally bioavailable.

| 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.
