| Outline of Final Research Achievements |
Dysfunction of ion channels leads to various diseases. Rational development of pharmaceuticals that modulate functions of ion channels is an urgent task in modern science. Ryanodine receptors are calcium ion release channels, and are selectively activated by ryanodine. Our study aimed at unified total synthesis and biological evaluation of ryanodine, natural and artificial ryanoids.
In this study, we developed a new strategy for assembly of the architecturally complex structure of ryanodine, and achieved unified total synthesis of ryanodine and five other natural ryanoids. Our practical syntheses enabled us to prepare the ryanoids for detailed investigation of their various biological functions. Moreover, the fluorescent labeled ryanodine was prepared for investigation of the molecular interaction between the synthetic molecules and ryanodine receptors.
