abstract = {Predicting the permeability coefficient (P) of drugs
permeating through the cell membrane is of paramount
importance in drug discovery. We here propose an approach
for calculating P based on bias-exchange metadynamics. The
approach allows constructing from atomistic simulations a
model of permeation taking explicitly into account not only
the “trivial” reaction coordinate, the position of the
drug along the direction normal to the lipid membrane plane,
but also other degrees of freedom, for example, the
torsional angles of the permeating molecule, or variables
describing its solvation/desolvation. This allows deriving
an accurate picture of the permeation process, and
constructing a detailed molecular model of the transition
state, making a rational control of permeation properties
possible. We benchmarked this approach on the permeation of
ethanol molecules through a POPC membrane, showing that the
value of P calculated with our model agrees with the one
calculated by a long unbiased molecular dynamics of the same
system.},
