Biological Activity

N-1-Naphthylthalamic acid is a polar auxin transport inhibitor. N-1-Naphthylthalamic acid destroys leaf initiation, KNOX protein regulation and leaf margin formation in maize.

NPA can be dissolved in sterile water containing 5 % ethanol to make a final concentration at 10 mg/L.

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.
