| Outline of Final Research Achievements |
Disease-specific changes of microenvironment could be utilized for diagnosis and drug delivery system. In this research, we have developed various fluorescent sensors for such change. For example, sensors for a specific range of pH, which show “OFF-ON-OFF” type of change and enable detailed analysis of physiological functions. And fluorescent sensors for viscosity change have also been developed. We focused on natural compounds as the source of such molecules, and fluorescent natural compounds, Amarastelline A and Nigakinone, were identified. Based on them, fluorescent compounds with unique and useful functions were also obtained. In addition, the function as a sensor was converted to that as a photoremovable protecting group. By using similar scaffold, we have developed protecting group, which could be photo-removed under a specific range of pH.
