| Abstract | Caco‐2 cell monolayers are widely used systems for predicting human intestinal absorption. This study was carried out to develop a quantitative structure–property relationship (QSPR) model of Caco‐2 permeability using a novel genetic algorithm‐based partial least squares (GA‐PLS) method. The Caco‐2 permeability data for 73 compounds were taken from the literature. Molconn‐Z descriptors of these compounds were calculated as molecular descriptors, and the optimal subset of the descriptors was explored by GA‐PLS analysis. A fitness function considering both goodness‐of‐fit to the training data and predictability of the testing data was adopted throughout the genetic algorithm‐driven optimization procedure. The final PLS model consisting of 24 descriptors gave a correlation coefficient (r) of 0.886 for the entire dataset and a predictive correlation coefficient (rpred) of 0.825 that was evaluated by a leave‐some‐out cross‐validation procedure. Thus, the GA‐PLS analysis proved to be a reasonable QSPR modeling approach for predicting Caco‐2 permeability. © 2002 Wiley‐Liss Inc. and the American Pharmaceutical Association J Pharm Sci 91:2230–2239, 2002 |
