A novel series of 11,12-cyclic carbonate azithromycin-3-O-descladinosyl-3-O-carbamoyl glycosyl derivatives were designed, synthesized, and evaluated for their antibacterial activities in vitro. Most of these compounds had significant antibacterial activity against seven kinds of susceptible strains. In particular, compound G1 exhibited the most potent activity against methicillin-resistant Streptococcus
设计、合成了一系列新的 11,12-环状碳酸酯阿奇霉素-3-O-descladinosyl-3-O-carbamoyl 糖基衍生物,并评估了它们的体外抗菌活性。这些化合物中的大多数对七种敏感菌株具有显着的抗菌活性。特别是,化合物 G1 对耐甲氧西林肺炎链球菌 943(MIC:1 μg/mL)、肺炎葡萄球菌 746(MIC:2 μg/mL)、化脓性链球菌 447(MIC:8 μg/mL)、和大肠杆菌 236(MIC:32 μg/mL),其活性分别是阿奇霉素的两倍、四倍、四倍、四倍和八倍。此外,化合物 G2 对耐甲氧西林金黄色葡萄球菌 MRSA-1(MIC:8 μg/mL)、肺炎链球菌 943(MIC:2 μg/mL)、肺炎葡萄球菌 746(MIC:2 μg/mL)和大肠杆菌236(MIC:32 μg/mL),它们的活性分别比阿奇霉素好 2、2、4 和 8 倍。对于耐甲氧西林金黄色葡萄球菌 MRSA-1,化合物
