从红树植物Ceriop Tagal的根中分离得到新的二萜甲氧基-8(14)-胡萝卜烯-15-酮(1)和3个已知的代谢产物:Et-8(14)-胡萝卜烯-15R,16-二醇(2),豆甾醇(3)和β-谷甾醇(4)。通过广泛的核磁共振、IR和MS分析,确定了它们的结构和相应的立体化学结构。化合物1、2、3和4对白背水蚤幼虫有明显的抑制作用,其EC50值分别为0.32±0.01、0.04±0.00、4.05±0.15和18.47±0.40µg/cm2,而对鲤鱼的毒性很低,LC_(50)均在10µg/cm2以上。
The new diterpene methoxy-ent-8(14)-pimarenely-15-one (1) and three known metabolites: ent-8(14)-pimarene-15R,16-diol (2), stigmasterol (3) and β-sitosterol (4), were isolated from the roots of the mangrove plant Ceriops tagal. Their structures and relative stereochemistry were elucidated by means of extensive NMR, IR and MS analysis. Compounds 1, 2, 3 and 4 exhibited significant antifouling activities against cyprid larvae of the barnacle Balanus albicostatus Pilsbry, with EC50 values of 0.32 ± 0.01, 0.04 ± 0.00, 4.05 ± 0.15 and 18.47 ± 0.40 µg/cm2, respectively, whereas their toxicities towards cyprids were very low, with LC50 values all above 10 µg/cm2.
