| Outline of Final Research Achievements |
This study aims syntheses of fluorescent probe of antifouling natural products. As lead compounds for antifouling materials, omaezallene (brominated compound) and dolastatin 16 (cyclic peptide) are selected becuase these exhibit strong antifouling activity along with very low toxicity toward cypris larvae of Amphibalanus amphitrite. Elucidation of molecular mechanism of antifouling activity expects the development of ideal antifouling material.
Syntheses of omaezallene derivatives was achieved, which includes fluorescent derivative. A new synthetic pathway to dolastatin 16 and the antifouling activity of synthetic sample were revealed. Functionalization method toward fluorescent compound was also developed.
