已从三种海绵中分离出六种萜类化合物和两种甾类化合物作为防污剂,即来自Smenospongia sp.的海松内酯(1)、裂叶海松内酯(2)、海松内酯25-乙酸酯(3)、(4 E,6 E)-脱氢海松内酯(4),来自Myrmekioderma dendyi的(+)-姜黄酚(5)和(+)-姜黄二醇(6),以及来自Topsentia sp.的三-2-氨基咪唑盐烷醇硫酸盐(7)和盐烷醇硫酸盐(8)。这些化合物对藤壶Balamis amphitrite的塞浦路斯幼虫表现出防污活性,但没有毒性,ECS 0值分别为0.24、0.80、0.53、2.7、2.5、2.8、4.0,和2.9 μgml-1。
Six terpenoids and two steroids have been isolated from three marine sponges as antifoulants, viz. manoalide (1), seco‐manoalide (2), manoalide 25‐acetate (3), (4E,6E)‐dehydromanoalide (4) from Smenospongia sp., (+)‐curcuphenol (5) and (+)‐curcudiol (6) from Myrmekioderma dendyi, and tri‐2‐aminoimidazolium halistanol sulfate (7) and halistanol sulfate (8) from Topsentia sp. These compounds showed antifouling activity but not toxicity against cypris larvae of the barnacle Balamis amphitrite, with ECS0 values of 0.24, 0.80, 0.53, 2.7, 2.5, 2.8, 4.0, and 2.9 μgml‐1 respectively.
