Membrane Permeability
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.
Macrocycle support:
Automatic detection and sampling of macrocycles via Prime’s advanced macrocycle sampling algorithm.
Partition energy “dG” Insert prediction:
Purely physics-based model, excellent for congeneric datasets.
RRCK cell-based assay Papp prediction:
Physics-based model tuned to predict RRCK (MDCK-LE) assay logPapp values.
