The tropical green seaweed Caulerpa taxifolia (VAHL) C. AGARDH (Caulerpales) which is invading the Mediterranean is shown to contain trace amounts of two further novel terpenes, 7,7-C-didehydro-6-hydroxy-6,7-dihydrocaulerpenyne (= (4S, 6S,1E)-3-[(Z)-acetoxymethylidene]-6-hydroxy-11-methyl-7-methylidenedodeca-1,10-dien-8-yne-1,4-diyl diacetate; 3a) and taxifolione (= 6-methylhept-5-en-3-yn-2-one; 4)
入侵地中海的热带绿色海藻Caulerpa taxifolia(VAHL)C. AGARDH(Caulerpales)含有痕量的另外两种新颖的萜烯7,7 - C - didehydro -6-hydroxy-6,7-dihydrocaulerpenyne( =(4 S,6 S,1 E)-3-[(Z)-乙酰氧基亚甲基] -6-羟基-11-甲基-7-甲基二烯基十二烷基-1,10-dien-8-yne-1,4-二乙酸二乙酸酯; 3a)和紫杉醇酮(= 6-甲基庚基5-en-3-yn-2-one; 4)。前者是迄今为止从该海藻中分离出的最活跃的毒素,无论体外还是体外海洋细菌生长的抑制剂,以及对海洋纤毛生物的细胞毒性剂。这表明三乙酸酯3a作为该海藻入侵地中海的辅助因子具有重要的生态毒理作用。此外,现在可以通过过氧酸环氧化环氧乙烷(1)以及6,7-环氧环氧丙烷(6b和6a)来获得几乎不具有毒性的10,11
