Celangulin-V (1) and podophyllotoxin (2) are both natural compounds with significant insecticidal activity. The identical and nonidentical dimers of celangulin-V and podophyllotoxin (3, 4, 5) were synthesized using succinic acid as the linker, and their insecticidal activities against 3rd instar larvae of Mythimna separata were tested. Only the identical dimer of celangulin-V (3) show some insecticidal activity.
Celangulin-V(1)和
鬼臼毒素(2)都是具有显著杀虫活性的天然化合物。以
琥珀酸为连接剂合成了celangulin-V和
鬼臼毒素的相同和非相同二聚体(3、4、5),并测试了它们对Mythimna separata三龄幼虫的杀虫活性。只有celangulin-V的相同二聚体(3)显示出一定的杀虫活性。
