Amdigenol D, a long carbon-chain polyol, isolated from the marine dinoflagellate Amphidinium sp

Abstract A novel polyol compound, amdigenol D, produced by the dinoflagellate Amphidinium sp. has been isolated. Its structure was elucidated by NMR spectroscopy and MS/MS analyses. Amdigenol D consists of a C101-linear carbon backbone including two core structures of amphidinol analogs. Amdigenol D is the longest amdigenol analog identified to date.
