Naloxegol oxalate (NKTR-118 oxalate; AZ-13337019 oxalate) is a peripherally-selective opioid antagonist for the treatment of opioid-induced constipation. Naloxegol oxalate inhibits opioid binding in μ-opioid receptors in the gastrointestinal tract. Chemically, naloxegol is a pegylated (polyethylene glycol-modified) derivative of α-naloxol. Specifically, the 5-α-hydroxyl group of α-naloxol is connected via an ether linkage to the free hydroxyl group of a monomethoxy-terminated n=7 oligomer of PEG.

|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 ≥ 30 mg/mL|
