从一种海洋甲藻Amphidinium sp.(Y-42)中分离得到六个新的大环内酯类化合物,它们分别是Amphidinolides H2(5),H3(6),H4(7),H5(8),G2(9)和G3(10)。除了10种含有两性环内酯H(1)、G(2)、B(3)和D(4)的两性环内酯(1-10)外,还检测了两性环内酯H(1)的5种衍生物(11-15)的细胞毒性,发现烯丙基环氧化物、S-顺式二烯部分、C-20位的酮对两亲性H(1)型大环内酯类化合物的细胞毒性起重要作用。
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.
