Adrenorphin (Metorphamide) is a opioid octapeptide, acting as a potent agonist of μ-opioid receptor, with Ki of 12 nM. The binding ratios of Ki for μ-opioid receptor/Ki for δ-opioid receptor is 0.04, and the binding ratios of Ki for μ-opioid receptor/Ki for κ-opioid receptor is 0.46. Adrenorphin potently inhibits catecholamine secretion evoked by 10 μM nicotine in cultured human pheochromocytoma 6 cells, with IC50 of 1.1 μM.

|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.
|Solubility||DMSO 48 mg/mL|
