RESUMO
Paeoniflorin, a monoterpene glucoside, is increasingly used in the clinical treatment of many diseases because it has a variety of pharmacological activities. Besides, paeoniflorin has been considered the characteristic chemical constituent of Paeoniaceae plants since it was first reported in 1963. Therefore, how to better develop and utilize paeoniflorin in Paeoniaceae has always been a research hotspot. We reviewed the current knowledge on paeoniflorin in Paeoniaceae, with particular emphasis on its distribution and influencing factors. Moreover, the limited understanding of the biosynthesis pathway has restricted the production of paeoniflorin by synthetic biology. This review provides insights into the post-modification pathway of paeoniflorin biosynthesis and proposes directions for further analysis in the future.
RESUMO
Plant natural products (PNPs) are important sources of innovative drugs. They are mainly obtained by isolation or extraction from plants. Low content and with structural analogues in plants result in high production cost, which restricts the research and application of PNPs. While biopathway construction by synthetic biology provides an alternative for production of PNPs. By biosynthetic pathway analysis of PNPs and reconstructing the biopathway in microorganisms, we can produce PNPs in cell factories efficiently. Recently, several predominantly international reports about biosynthesis of PNPs and its synthetic biology production, triggered the researches of PNPs. Abundant traditional Chinese medicine resources and profound cultural heritage of Chinese medicine make biosynthesis pathway analysis of PNPs to be a research hotspot. And some of the studies have achieved significant progress. Here, recent progress in the biosynthesis of plant natural products and its synthetic biology was reviewed. In particular, the application of new methods and technologies in recent years were summarized and discussed. This will provide reference for the biopathway construction of plant natural products.
