compound introduction
环铁蛋白是从|曲霉|中分离出来的一种不寻常的二酮哌嗪。尚未对环铁蛋白进行广泛研究，但据报道其对鳞翅目作物害虫Helicoverpa zea具有杀虫活性。最近，环赤霉素发现了一种次生代谢物标准品用于曲霉中的多相分类。 Cycloechinulin is an unusual diketopiperazine isolated from|Aspergillus ochraceus|. Cycloechinulin has not been extensively studied but has been reported to exhibit insecticidal activity against the lepidopteran crop pest Helicoverpa zea. Recently,cycloechinulin has found use a secondary metabolite standard for polyphasic taxonomy in Aspergillus.
