为了寻找新的环境友好型抗氧化剂,从中药蛇床子中分离得到4种香豆素类化合物,分别为蛇床子素(1)、欧前胡素(2)、异茴芹素(3)和橙皮烯醇(4)。以蛇床子素为原料,合成了5个香豆素衍生物:8-环氧戊基香豆素(5)、meranzin水合物(6)、2′-deoxymetranzin水合物(7)、8-甲基丁烯醛香豆素(8)和micromarin-F(9)。化合物1、2、4、7对白脊藤壶幼虫定居有较强的抑制活性,EC 50分别为4.64、3.39、3.38、4.67 μg mL−1。化合物8可以显著抑制稻纵卷叶螟的幼虫沉降,EC 50值为3.87 μg mL-1。不同功能基团对AF活性的影响表明,异戊烯链C-5′和C-2′/C-3′上的功能基团对AF活性有影响。
In the search for new environmental friendly antifouling (AF) agents, four coumarins were isolated from the herbal plant Cnidium monnieri, known as osthole (1), imperatorin (2), isopimpinellin (3) and auraptenol (4). Furthermore, five coumarin derivatives, namely 8-epoxypentylcoumarin (5), meranzin hydrate (6), 2′-deoxymetranzin hydrate (7), 8-methylbutenalcoumarin (8), and micromarin-F (9) were synthesized from osthole. Compounds 1, 2, 4, 7 showed high inhibitory activities against larval settlement of Balanus albicostatus with EC50 values of 4.64, 3.39, 3.38, 4.67 μg mL−1. Compound 8 could significantly inhibit larval settlement of Bugula neritina with an EC50 value of 3.87 μg mL−1. The impact of functional groups on anti-larval settlement activities suggested that the groups on C-5′ and C-2′/C-3′ of isoamylene chian could affect the AF activities.
