Biological Activity

AUT1 is a Kv3 potassium channel modulator which increases whole currents mediated by human Kv3.1b and Kv3.2a channels, with a concomitant leftward shift in the voltage-dependence of activation, while having a less potent effect on hKv3.3 currents. AUT1 has pEC50 values of 5.33 and 5.31 for human recombinant Kv3.1b and Kv3.2a, respectively, exhibits 10-fold lower potency at human recombinant Kv3.3 channel (pEC50, 4.5).

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
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.
