在我们从海洋环境中寻找新的天然产物的过程中,我们从海洋发光杆菌中发现了广泛的环肽,与P. halotolerans密切相关。细菌的化学指纹图谱显示主要是非核糖体肽合成酶(NRPS)样化合物,包括已知的吡咯硫抗生素全霉素和广泛的肽,从二酮哌嗪到500-900 Da的环缩酚酸肽。从沉淀级分的组分纯化导致四个新的环缩酚酸肽的分离和结构鉴定,angercheumicin F,G,H和I。已知由金黄色葡萄球菌的agr群体感应系统控制的毒力基因的表达,尽管在较小程度上比先前描述的来自发光杆菌属的相同菌株的磺胺类药物干扰。
During our search for new natural products from the marine environment, we discovered a wide range of cyclic peptides from a marine Photobacterium, closely related to P. halotolerans. The chemical fingerprint of the bacterium showed primarily non-ribosomal peptide synthetase (NRPS)-like compounds, including the known pyrrothine antibiotic holomycin and a wide range of peptides, from diketopiperazines to cyclodepsipeptides of 500–900 Da. Purification of components from the pellet fraction led to the isolation and structure elucidation of four new cyclodepsipeptides, ngercheumicin F, G, H, and I. The ngercheumicins interfered with expression of virulence genes known to be controlled by the agr quorum sensing system of Staphylococcus aureus, although to a lesser extent than the previously described solonamides from the same strain of Photobacterium.
