用表达VioA基因G231L变体的重组质粒pWLI823在海洋源短杆菌7002-073中异源表达,获得了一个新的14元同源二聚体大二烯内酯brevidiolide(3)和4个已知的芳香化合物(1、2、4和5)。通过液相色谱-质谱和二维核磁共振分析对1 ~ 5个化合物的结构进行了鉴定。在对多药耐药(MDR)菌株的抑菌活性评价中,5对金黄色葡萄球菌CCARM 3090和肺炎克雷伯菌ATCC 13883表现出显著的生长抑制作用,最小抑制浓度(MIC)值为3.12µg/mL。
A new 14-membered homodimeric macrodiolide, brevidiolide (3), along with four known aromatic compounds (1, 2, 4 and 5) were obtained by heterologous expression of the recombinant plasmid pWLI823 expressing the G231L variant of VioA in the marine-derived Brevibacterium sp. 7002-073. The structures of 1–5 were elucidated on the basis of LC-MS and 2D NMR spectroscopic analyses. In the evaluation for the antibacterial activities of the compounds against multi-drug resistant (MDR) strains, 5 showed notable growth inhibition against Staphylococcus aureus CCARM 3090 and Klebsiella pneumoniae ATCC 13883, with a minimum inhibitory concentration (MIC) value of 3.12 µg/mL.
