Quantitative structure-activity relationship (QSAR) models were developed for the prediction of bovine hoof membrane permeability in an effort to gain insight into the rate of penetration of antimycotics through the nail plate. Numerical descriptors based on chemical structure were calculated for a set of 14 drugs, mainly antimycotics. The descriptors were then placed into one of three classes based on level of complexity and demand for computational resources. Models using the various classes of structural descriptors were developed using ridge regression, principal component regression, and partial least squares. Results indicate that permeability of antimycotics can be modeled based on structural descriptors alone, without the need for experimental data. As such, predictions can be made about the permeability of hypothetical compounds of similar structure not yet synthesized. However, additional data are required to allow for reliable modeling of human nail plate permeability.
