[structure: see text] Two novel antiinsectan indole diterpenoids, thiersinines A (1) and B (2), along with seven known paxilline-type compounds, were isolated from organic extracts of a new Penicillium species (P. thiersii NRRL 28147). The structures of 1 and 2 were determined by analysis of 2D NMR data. Thiersinines A and B possess a unique spirocyclic subunit that is unprecedented in previously known compounds of this class. Both compounds exhibit potent activity against the fall armyworm (Spodoptera frugiperda).
[结构:见正文] 从一种新的青霉属物种(蒂尔西青霉NRRL 28147)的有机提取物中分离出两种新型抗昆虫吲哚二萜类化合物,蒂尔西菌素A(1)和B(2),以及七种已知的青霉素型化合物。通过二维核磁共振数据的分析确定了1和2的结构。蒂尔西菌素A和B具有独特的螺环亚基,这在该类先前已知的化合物中是前所未有的。这两种化合物对草地贪夜蛾(Spodoptera frugiperda)均表现出强效活性。
