Biological Activity

Pralatrexate (Folotyn) is an antifolate, and structurally a folate analog. It acts as an inhibitor of dihydrofolate reductase. It is selective for the reduced folate carrier type 1. Its IC50 is < 300 nM in some cell lines.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 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 resveratrol of 11.2 mg/kg.
