Omaezallene derivatives (nor‐bromoallene, nor‐bromodiene, and bromoenynes) were successfully synthesized. Their antifouling activity and toxicity to the cypris larvae of the barnacle Amphibalanus amphitrite and ecotoxicity to the marine crustacean Tigriopus japonicus were studied. It was revealed that the two side chains of omaezallene were essential to its antifouling activity because the activities
成功合成了 Omaezallene 衍生物(去甲溴丙二烯、去甲溴二烯和溴烯炔)。研究了它们对藤壶 Amphibalanus amphitrite 的 cypris 幼虫的防污活性和毒性以及对海洋甲壳动物 Tigriopus japonicus 的生态毒性。结果表明,由于去甲溴丙二烯和去甲溴二烯的活性显着降低,omaezallene的两条侧链对其防污活性至关重要。发现溴烯炔表现出与 omaezallene 相当的有效防污活性,具有低毒性和生态毒性。溴烯骨架的制备比 omaezallene 中溴二烯部分的制备要容易得多。基于溴烯炔的防污活性,还进行了荧光探针的合成及其生物活性的评价。
