Lipophilicity study of salicylamide.

Molecular lipophilicity was studied using salicylamide as a model drug. Log P value for the target compound was experimentally determined by the shake-flask method and calculated using nine different computer programs based on atom/fragment contributions, structural parameters, atom-type electrotopological-state indices and neural network modeling, or topological structure descriptors. Our analysis demonstrates good agreement between the experimentally observed log P value of salicylamide and the value calculated by the CSLogP program, based on topological structure descriptors and electrotopological indices.
