Polydora websterii, a harmful lugworm that has serious adverse effects on pearl oyster cultivation, was inhibited by a marine diterpene, crenulacetal C, isolated from the brown alga Dictyota dichotoma, Based on consideration of the activity-structure relationship, several synthetic compounds having an aromatic moiety with a hydroxyalkyl chain were prepared. Bioassay using larvae of Polydora websterii as well as pearl oysters (Pinctada fucata martensii) suggested that 1-(2-furyl)-1-nonanol was the most promising inhibitor.
恶性虫 Polydora websterii 是一种对珍珠贝养殖产生严重不良影响的有害泥环虫,它受到从褐藻 Dictyota dichotoma 中分离出的海洋二萜类化合物 crenulacetal C 的抑制。基于对活性-结构关系的考虑,合成了几种具有芳香基团和羟烷基链的化合物。使用 Polydora websterii 幼虫和珍珠贝 (Pinctada fucata martensii) 的生物测定表明,1-(2-furyl)-1-壬醇是最有前景的抑制剂。
