A novel series of C(12) ethyl erythromycin derivatives have been discovered which exhibit in vitro and in vivo potency against key respiratory pathogens, including those resistant to erythromycin. The C(12) modification involves replacing the natural C(12) methyl group in the erythromycin core with an ethyl group via chemical synthesis. From the C(12) ethyl macrolide core, a series of C(12) ethyl ketolides
已经发现了一系列新的C(12)乙基红霉素衍生物,它们对关键的呼吸道病原体(包括对红霉素有抗性的病原体)表现出体外和体内效力。C(12)修改涉及通过化学合成用乙基取代红霉素核心中的天然C(12)甲基。从C(12)乙基大环内酯核心制备了一系列C(12)乙基酮缩酮,并测试了其对一组相关临床分离株的抗菌活性。无论是由于核糖体甲基化(erm)还是外排(mef),都发现了几种对大环内酯类敏感和耐药菌有效的化合物。特别是,C(12)乙基酮缩酮4k,4s,4q,4m和4t具有相似的抗菌谱,并且具有与商业酮内酯telithromycin相当的活性。
