Physics-based, accurate predictions of passive membrane permeability
The Advantage of a Physics-based Model
Unlike QSAR-based modeling, physics-based models offer more robustness across diverse chemistries, due to the models’ ability to address conformation dependent phenomena such as internal hydrogen-bonding, which can have a dramatic effect on permeability but cannot be accurately modeled by QSAR approaches.
