| Outline of Final Research Achievements |
In this research, we have attempted to develop new hyperpolarized chemical probes toward the redox analysis in vivo. To this end, we have utilized the magnetic resonance analysis and the hyperpolarization technique. The hyperpolarization is a highly potential method to enhance magnetic resonance signals dramatically. However, the hyperpolarization method has a shortcoming, which is the short lifetime of the polarized spin state in solution. To resolve this problem, first we have explored the structure having long hyperpolarization lifetime. We have successfully explored the potent structures. Then we have found the mechanisms to induce the large chemical shift change for sensing of redox balance. We expect these findings would be valuable to develop redox-responsible hyperpolarized sensors.
