Amphidinins C-F, amphidinolide Q analogues from marine dinoflagellate Amphidinium sp.

Four new polyketides, amphidinins C-F (1-4), have been isolated from the culture broth of symbiotic dinoflagellate Amphidinium sp. The analysis of their spectral data revealed that amphidinins C-F (1-4) were 4,5-seco-analogues of amphidinolide Q (5). The absolute configurations of the new compounds were elucidated by the combination of J-based configuration… CONTINUE READING
