Recently a new series of nitrooxy-acyl derivatives of salicylic acid (SA) was described presenting similar anti-inflammatory activities but reduced or no gastrotoxicity compared to aspirin. In this work, lipophilicity and permeability profiles of SA derivatives were performed to evaluate their ADME properties related to oral or transdermic delivery. All tested compounds showed potential good passive permeation through gastrointestinal track and also through percutaneous barrier which could be a way to avoid the first hepatic pass.
