Sodium metatungstate (Sodium polyoxotungstate) is a potent ecto-nucleoside triphosphate diphosphohydrolase (ENTPDase) inhibitor, with Ki values of 2.58 μM, 3.26 μM, and 28.8 μM for NTPDase 1 (CD39), NTPDase 3 and NTPDase 2 respectively. Sodium metatungstate inhibits ATP breakdown but also blocks central synaptic transmission, an action independent of NTPDase inhibition.

|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.
