RESUMO
Mecicinal plants boast abundant natural compounds with significant pharmacological activity, and such compounds, featuring diversified and complex structures, can be used for research and development of drugs. At present, these natural compounds are directly extracted from herbs which, however, suffer from damaged wild resources and shortage of planting resources attributing to the increasing demand. Moreover, the low content in medicinal plants and complex structures are another challenge to the research and development of drugs. Heterologous synthesis with synthetic biology methods is a solution that has attracted wide attention. Synthetic bio-logy for the production of natural active compounds in Chinese medicinal plants involves the exploration of key enzymes in compound bio-synthetic pathways from plants, analysis of enzyme functions and mechanisms, and reconstruction and optimization of biosynthetic pathways in microorganisms for efficient synthesis of compounds. This study briefed the development process of synthetic biology and the biosynthetic pathways of terpenoids, alkaloids, and flavonoids, and summarized the related strategies of synthetic biology such as the reconstruction and optimization of metabolic pathways, regulation of fermentation process, and strain improvement, and the latest applications of heterogeneous synthetic biology in the production of natural compounds from Chinese medicinals. This study is expected to serve as a reference for the efficient production of terpenoids, alkaloids, flavonoids, and other active compounds from Chinese medicinal plants with strategies of synthetic biology.
