Aminocarbonyloxymethyl esters based on (S)-amino acid carriers were synthesised and evaluated as potential prodrugs of carboxylicacid agents. In addition, the compounds were evaluated as topical prodrugs with the aim of improving the dermal delivery of two non-steroidal anti-inflammatory agents: naproxen and flufenamic acid. The lipophilicities of these compounds were determined and their hydrolyses
pathway was mainly affected by the steric bulk of the nitrogen substituents in the amide moiety, the reactivity being reduced with larger N-substituents. Hydrolysis in human plasma appeared to be mediated by enzymic processes and is dependent upon the steric bulk in the carboxylic acid moiety. Plasma hydrolysis rates were inversely dependent on the lipophilicity of the ester. CONCLUSIONS Derivatives containing
