"The data set consists of 85 compounds, for which Wessel and co-workers gathered %HIA values from the literature. Sixteen of these 85 structures have Caco-2 cell permeability data, originating from Artursson and Karlsson that were used in the QSAR models proposed by Van de Waterbeemd et. al. and by Norinder et. al. In addition, Yazdanian et. al. reported Caco-2 cell permeability data for 29 of these 85 structures. Thus, three experimental measures were used to derive our QSAR model".
