| Outline of Final Research Achievements |
For the development of multicolor imaging of fluorine-MRI, the aim of this study was to prepare the ionic liquid nanoparticles (ILNPs) using the ionic liquid (IL) having fluorine atoms, to evaluate their pharmacodynamics in mice and further to synthesize a novel fluorine-MRI probe. The NMR spectroscopic results, 1H-, 19F, 31P- and 1H-1H NOESY, showed that the ILNP formed an IL-in-water type emulsion in which droplets of IL were surrounded by the surfactants. In addition, the ILNP accumulated higher in kidney than in liver, indicating that fluorine-containing anions of IL were immediately released from the ILNP in blood circulation after the administration in mice. Also, a fluorine-MRI probe could be newly synthesized from the glutathione, which is a substrate for γ-glutamyltransferase which exists in high concentration in cancer cells.
