Abstract: A TOPological Substructural MOlecular DEsign (TOPS-MODE) was used to predict the flux across human skin permeability coefficient for heterogeneous set of compounds. The obtained model explained more than 84 % of data variance and shown the importance of the hydrogen bonding and the hydrophobicity to describe the property under study. Finally, the TOPS-MODE was used to calculate the contribution of different fragments to the human skin coefficient for studied compounds. The present approximation proved to be a good method to studying the permeability skin human coefficient for the heterogeneous compounds, which could be extended to other series of compounds.
