Inter-species scaling of PD Models: New expression of in vivo potency

This webinar introduces a redefined model for In Vivo Potency, moving beyond standard in vitro binding to account for physiological variables.

Potency is now characterized by the interaction of three specific rates:

  • Binding Kinetics: The kon and koff rates.

  • Target Turnover kdeg: The natural degradation rate of the physiological target.

Irreversible Complex Loss koff, RC: The rate at which the drug-target complex is permanently removed from the system.
