12-lactoketolides, with activity against macrolide-resistant streptococci, are described. Structurally, these macrolide antibiotics are characterized by a heteroaryl side chain attached to the macrolactone core through a carbamate linkage at the C6 position, as well as 11,12-gamma-lactone and 3-keto functionalities. The synthesis and antibacterial activity of this new series of ketolides are discussed.
描述了一系列新的红霉素A衍生物,即6-O-杂芳基氨基甲酰基-11,12-乳酮醇内酯,对大环内酯类耐药链球菌具有活性。从结构上讲,这些大环内酯类抗生素的特征是杂芳基侧链通过C6位置的氨基甲酸酯键连接到大内酯核心上,以及11,12-γ-内酯和3-酮官能团。讨论了该新系列酮醇化物的合成和抗菌活性。
