| Research Abstract |
Haterumalides and biselides are cytotoxic macrolide isolated from the Okinawan marine animals. Interestingly, haterumalide NA showed strong toxicity against brine shrimp, while haterumalide NA methyl ester and biselide A are less toxic. I planned to synthesize haterumalide derivatives and to evaluate its biological activity. As a result, I elucidated that chloroolefin part of haterumalides is essential for the strong cytotoxicity of haterumalides. Also, I have achieved the synthesis of core carbon framework of biselide E.
