A series of novel 9-O-acetyl-4′-substituted 16-membered macrolides derived from josamycin has been designed and synthesized by cleavage of the mycarose of josamycin and subsequent modification of the 4′-hydroxyl group. These derivatives were evaluated for their in vitro antibacterial activities against a panel of Staphylococcus aureus and Staphylococcus epidermidis. 15 (4′-O-(3-Phenylpropanoyl)-9-
已设计和合成了一系列新的衍生自交联霉素的9 - O-乙酰基-4'-取代的16元大环内酯类化合物,方法是通过裂解交联霉素的直链淀粉和随后修饰4'-羟基基团来合成。对这些衍生物的体外抗菌活性进行了评价,对一组金黄色葡萄球菌和表皮葡萄球菌的抗菌活性。15(4'- ø - (3-苯基丙酰基)-9- ø -乙酰基desmycarosyl交沙霉素)和16(4'- ö丁酰基-9- ø -乙酰基desmycarosyl交沙霉素)显示出可比较的活动,以交沙霉素针对金黄色葡萄球菌(MSSA)和表皮葡萄球菌(MSSE)。
