链霉菌聚酮类次生代谢产物及其生物合成基因簇

Polyketide antibiotics produced by polyketide synthase in streptomyces-A review

聚酮类抗生素在工业、农业和医药方面都具有重要的商业价值,至今通过美国FDA认证的聚酮类药物超过40个。随着分子生物学的发展,人们开展了抗生素合成基因簇的研究,并以此为基础发展了组合生物学,形成天然产物化学与分子生物学相结合的跨学科研究领域。本文以链霉菌为对象,对链霉菌产生的聚酮类抗生素的药物应用、聚酮合成酶(PKS)的研究及聚酮类药物的开发策略与前景作了相关介绍。

Polyketides have played an important role in antibiotic drug discovery with most antibacterial drugs being derived from a natural product or natural product lead. Furthermore, the biosynthetic gene clusters for numerous bioactive polyketides have been intensively studied over the past 15 years. This paper focuses on the polyketide drugs approved by US-FDA and takes a general view in the antibiotics produced by polyketide synthase in streptomyces.
