对结构复杂的发酵产物进行化学修饰,这一过程被称为半合成,是发现和生产用于治疗各种感染性疾病的抗生素的重要工具。然而,以这种方式获得的许多治疗剂不再有效,因为细菌对许多这些化合物产生了耐药性。在这篇手稿中,我们描述了一个实用的,完全合成的大环内酯类抗生素的路线,通过简单的化学积木的收敛组装,与不同的结构不可能通过传统的半合成。通过我们的聚合方法合成了300多个新的大环内酯类抗生素候选物以及研究药物索利霉素。针对一组致病菌的新型化合物的评估显示了许多抗生素候选物,对目前使用的大环内酯类耐药菌株具有疗效。我们在此描述的化学为发现新的大环内酯类抗生素提供了一个平台,也可以作为其生产的基础。
The chemical modification of structurally complex fermentation products, a process known as semisynthesis, has been an important tool for the discovery and manufacture of antibiotics for the treatment of various infectious diseases. However, many of the therapeutics obtained in this way are no longer efficacious, as bacterial resistance to many of these compounds has developed. In this manuscript, we describe a practical, fully synthetic route to macrolide antibiotics via the convergent assembly of simple chemical building blocks, with diverse structures not possible by traditional semisynthesis. More than 300 new macrolide antibiotic candidates, as well as the investigational drug solithromycin, were synthesized by our convergent approach. Evaluation of the novel compounds against a panel of pathogenic bacteria revealed many antibiotic candidates, with efficacy against strains resistant to macrolides in current use. The chemistry we describe herein provides a platform for the discovery of new macrolide antibiotics and may also serve as a basis for their manufacture.
