A new tetrapeptide D-Phe-L-Val-D-Val-L-Tyr (1), along with three known diketopiperazines and pseurotin A, were isolated from the culture of Penicillium canescens, collected from pollen from beehives, in a screening for new antimicrobial products from unexplored sources. The structure of the tetrapeptide, which exhibits antifungal activity comparable with that of the commercial product benomyl against
从蜂窝状青霉菌的花粉中收集了一种新的四肽D-Phe-L-Val-D-Val-L-Tyr(1)以及三种已知的二酮哌嗪和假单胞菌素A,用于筛选蜂胶。来自未开发来源的新抗菌产品。通过分光光度法(2D-NMR,MS和MS / MS)确定了四肽的结构,该四肽的结构具有与市售产品苯菌灵相当的抗真菌植物病原镰刀菌的抗真菌活性,并确定了序列与真实的合成异构体肽相比。
