摘要:
青蒿素是应用广泛的一线抗疟药。现在市售的青蒿素主要是从植物中提取出来的, 含量稀少和需求广泛导致青蒿素供应不稳定。建立一种环境友好、廉价的生产青蒿素的方法将是未来解决青蒿素来源问题的有效方法。通过合成生物学技术来制备青蒿素, 利用细胞工厂将是未来青蒿素生产的主要方式。本综述简单介绍了青蒿素的生物合成途径, 并对青蒿素生物合成相关基因, 如紫穗槐-4, 11-二烯氧化酶基因、细胞色素P450氧化还原酶基因、青蒿醛双键还原酶和醛脱氢酶基因进行了重点介绍。此外, 本综述针对近年来青蒿素合成生物学发展的特点以及影响底盘细胞制备目的产物的因素进行了详细的论述。
Abstract:The first-line drug artemisinin is widely used against malaria. Commercially available artemisinin is extracted from plants. However, the lack of sufficient raw material, artemisinin and the cost associated with the drug’s manufacture have limited the supply of ACT to most malaria sufferers in the Developing World. As such, it is important to develop a low cost, fine to environment and high-quality method to supply sufficient and reliable quantities of artemisinin in the future. The field of synthetic biology, which utilizes cell factories to manipulate microbial metabolism to enhance the production of artemisinin and its intermediates, has a particularly strong impact by providing new platforms for chemical production. After a brief introduction of the artemisinin biosynthetic pathway, the present review focuses on the introduction of artemisinin biosynthetic genes, such as the genes encoding amorpha-4, 11-diene monooxygenase, NADPH: cytochrome P450 oxidoreductase, artemisinic aldehyde ?11(13) reductase and aldehyde dehydrogenase. The review also addresses general considerations for potential contributions of synthetic biology to artemisinin production, with an emphasis on factors influencing interest compounds production in chassis cells.
