The 34 potently pig pheromonal odorants (1-32, 5755 & 7113) through structure-based virtual screening and ligand-based virtual screening method were selected and their ADMET and pharmacokinetics characters were evaluated and discussed quantitatively. The pheromonal odorants were projected on the following pre-calculated models, Caco-2 cell permeability, blood-brain barrier permeation, hERG inhibition and volume-distribution. From the results of in silico study, it is found that an optimal compound (31) either penetrating or have a little (Pcaco2=－8.143) for Caco-2 cell permeability, moderate penetrating ability (PBBB=0.082) for blood-brain barrier permeation, the low QT prolongation (PhERG=1.137) for the hERG K+ channel inhibition, and low distribution into tissues (PVD=－5.468) for volume-distribution. Therefore, it is predicted that the compound (31) a topical application may be preferable from these based foundings.
