Photophysical probes to assess the potential of cholic acid aggregates as drug carriers

The two enantiomers of the nonsteroidal antiinflammatory drug naproxen and of its methyl ester have been selected as representative probes with markedly different hydrophobicity to assess the potential of cholic acid aggregates as drug carriers by means of photophysical techniques. The different distribution of the probes between bulk solution and aggregates has been assessed by quenching of their singlet and triplet excited states by iodide and nitrite anions, respectively. This straightforward photophysical methodology can, in principle, be extended to a variety of drugs containing a photoactive chromophore. © 2012 American Chemical Society.We gratefully acknowledge financial support from the Generalitat Valenciana (GV/2009/104 and Prometeo Program 2008/090), the Spanish Government (Red RETICS de Investigacion de Reacciones Adversas a Alergenos y Farmacos (RIRAAF)), CTQ2009-13699 and Predoctoral FPU fellowship AP2008-03295 for M.
