Six new macrolides, amphidinolides H2 (5), H3 (6), H4 (7), H5 (8), G2 (9), and G3 (10), have been isolated from a marine dinoflagellate Amphidinium sp. (strain Y-42). Cytotoxicity of five derivatives (11-15) of amphidinolide H (1) in addition to 10 amphidinolides (1-10) containing amphidinolides H (1), G (2), B (3), and D (4) was examined, and it was found that the presence of an allyl epoxide, an S-cis-diene moiety, and the ketone at C-20 was important for the cytotoxicity of amphidinolide H (1)-type macrolides.
