10-membered microbial macrolides proposed to be generated from their precursors presaccharothriolides X–Z. Previously, we isolated presaccharothriolide X, and its unique natural prodrug-like properties have intrigued us. However, the other congeners were not detected. Herein, we detected presaccharothriolide Z using our highly sensitive labeling reagent. Moreover, chemical synthesis of presaccharothriolide
Saccharothriolides A-F 是 10 元微生物大环内酯类,建议由其前体 presaccharothriolides X-Z 产生。此前,我们分离出前糖三内酯 X,其独特的天然前药样特性引起了我们的兴趣。然而,没有检测到其他同系物。在这里,我们使用我们的高灵敏度标记试剂检测到 presaccharothriolide Z。此外,还实现了糖三内酯类大环内酯类首个全合成的前糖三内酯Z的化学合成,并确定了前糖三内酯Z的结构和生物活性。
