中药是中华民族的文化瑰宝,也是我国在新药创制领域的重要驱动力.许多中药材来源于稀缺物种,其药效物质的规模化获取困难,是制约中药新药创制研究的重要瓶颈.合成生物学的出现和快速发展为解决这一瓶颈问题提供了新的途径.目前,中药药效物质的合成生物学研究在单个药效分子的生物制备方法上取得了重要进展.中药的药效主要源于多成分作用的叠加和协同,所以药效成分群是中药药效物质的主要形式,然而针对药效成分群的合成生物学研究鲜有报道.建立中药药效成分群合成生物技术的关键是精确调控组成分子的比例,从而产出优质药效成分群.本文首先总结了挥发油、总皂苷、总黄酮、总木脂素、总生物碱等重要类型中药药效成分群形成机制的研究进展.然后,重点以檀香挥发油为例,介绍如何通过酶工程和代谢工程的联合运用实现药效成分群成分比例和产量的双重优化.最后,对中药药效成分群合成生物学领域的未来研究重点进行了展望,包括:(1)加强中药药效成分群生物合成途径解析方面的研究,重点深入阐明复杂药效成分群的形成机制;(2)加强代谢优化手段方面的创新研究,重点揭示未知代谢调控机制并基于此发展创新调控策略;(3)加强酶工程方法学的创新研究,重点发展新型理性设计和定向进化的联用技术以及人工智能辅助的酶工程技术.
Advances in synthetic biology for producing potent pharmaceutical ingredients of traditional Chinese medicine
Traditional Chinese medicine(TCM)is a treasure of Chinese civilization and also a good mine for drug development in China.Many TCM components come from rare biological species including plants,animals,and insects,making the preparation of these TCM pharmaceutical substances at large scales a bottleneck that substantially impedes TCM-based drug development.However,the rapid development of synthetic biology has provided a strategy for addressing this challenge.At present,significant progress has been made in the bio-production of individual TCM components,but the efficacy of TCM is mainly due to the synergistic effect of those ingredients,which are termed as pharmaceutical ingredient groups.Reports on constructing the bio-production platform of pharmaceutical ingredient groups are limited.Herein,we summarize research progress in the biogenic mechanism of important TCM pharmaceutical ingredient groups,such as volatile oils,saponins,flavonoids,lignans and alkaloids.Some individual components of pharmaceutical ingredient groups(e.g.ginsenosides)are synthesized by multiple branching pathways,which can be produced and formatted thereafter.On the other hand,some pharmaceutical ingredients such as sandalwood oil can be synthesized through single pathways/enzymatic reactions by engineering the key enzymes to optimize their ratio.We comment the strategy of combining enzyme engineering and metabolic engineering to optimize both the production of pharmaceutical ingredient groups and their ratio.At the end,we outline the prospect of synthetic biology research for producing pharmaceutical ingredient groups,including:(1)complete clarification of the biogenic mechanism of more complex pharmaceutical ingredient groups,(2)development of novel metabolic engineering approaches for breaking through homogenization of methodology,and(3)optimization of the catalytic characteristics of key synthetic enzymes by combining rational design and directed evolution.
