Penicipyrrodiether A, an adduct of GKK1032 analogue and phenol A derivative, was isolated from a culture of marine-associated fungus Penicillium sp. ZZ380 and represents the first example of this type of fungal metabolite. Its structure was elucidated by extensive spectroscopic analyses, including 1D- and 2D-NMR, HRESIMS, MS/MS, and electronic circular dichroism calculation as well as single-crystal X-ray diffraction. Penicipyrrodiether A showed antibacterial activity in inhibiting the growth of methicillin-resistant Staphylococcus aureus with a MIC value of 5.0 μg/mL. Its plausible pathway for biosynthesis has been proposed.
从海洋来源真菌 Penicillium sp. ZZ380 的培养物中分离得到了 Penicipyrrodiether A,这是一种 GKK1032 类似物和酚 A 衍生物的加合物,代表了此类真菌代谢产物的首例。通过广泛的光谱分析,包括 1D 和 2D-NMR、HRESIMS、MS/MS 和电子圆二色性计算以及单晶 X 射线衍射,阐明了其结构。Penicipyrrodiether A 表现出抑制耐甲氧西林金黄色葡萄球菌生长的抗菌活性,其 MIC 值为 5.0 μg/mL。提出了其可能的生物合成途径。
