pirlimycin and other related compounds. These dual modifications were accomplished by using methyl α-thiolincosaminide as a starting material. As a result of these dual modifications, the antibacterial activities were improved compared with those of compounds with a single modification at the C-7 position. The antibacterial activities of selected compounds in this report against macrolide-resistant
描述了在C-6和C-7位置修饰的
林可霉素衍
生物的设计和合成。C-7位的取代基是5-芳基-1,3,4-
噻二唑-2-基-
硫基,该基团对带有erm
基因的耐大环内酯性肺炎链球菌和化脓性链球菌产生抗菌活性。在应用有关Pirlimycin和其他相关化合物的信息时,还探索了C-6位的其他修饰。这些双重修饰是通过使用甲基α-
硫代林糖胺作为起始原料来完成的。这些双重修饰的结果是,与在C-7位置具有单一修饰的化合物相比,抗菌活性得到了提高。本报告中所选化合物对大环
内酯类耐药肺炎链球菌和肺炎链球菌的抗菌活性。
