Research Abstract |
Bioorganic studies on novel modes of antitumor/cytototic activities of aplyronine A, aurilide, and haterumalides are effected. A hybrid analog between aplyronine A and mycalolide B was synthesized, and its bioactivities were evaluated. Target biomolecule of aurilide was identified to be prohibitin, a mitochondrial protein, which stabilized the tubular structure of mitochondria. Aurilide binds to probititin, which resulted in the fragmentation of mitochondoria. Analogs of haterumalides were synthesized, and their cytotoxicity was evaluated.
