我们报告的生产,分离和结构鉴定的倍半萜异terocarpolone从阿巴拉契亚分离链霉菌种RM-14-6。虽然isopterocarpolone以前被提出作为一种假定的植物代谢产物,但目前的研究突出了isopterocarpolone的第一个天然细菌生产和使用1D和2D NMR光谱和HR-ESI质谱的isopterocarpolone的第一个完整表征。考虑到密切相关的代谢产物(土臭素或5-表马兜铃烯)的生物合成,异蝶罗酚酮的结构也表明一种或多种独特的酶促转化的潜在参与。在这种情况下,这项工作也为阐明潜在的新型细菌生物合成机制奠定了基础。
We report the production, isolation and structure elucidation of the sesquiterpene isopterocarpolone from an Appalachian isolate Streptomyces species RM-14-6. While isopterocarpolone was previously put forth as a putative plant metabolite, the current study highlights the first native bacterial production of isopterocarpolone and the first full characterization of isopterocarpolone using 1D and 2D NMR spectroscopy and HR-ESI mass spectrometry. Considering the biosynthesis of closely related metabolites (geosmin or 5-epiaristolochene), the structure of isopterocarpolone also suggests the potential participation of one or more unique enzymatic transformations. In this context, this work also sets the stage for the elucidation of potentially novel bacterial biosynthetic machinery.
