迫切需要发现新的药物来解决抗生素耐药性的紧迫问题。自1954年以来,大环内酯类抗生素如红霉素(1)是安全的广谱抗生素。本文报道了4,8,10-三去甲基泰利霉素(3)的合成和评价,它是第三代药物泰利霉素(2)的一种新的去甲基类似物,泰利霉素(2)是1的半合成衍生物。抗生素3具有抗菌活性,对耐药菌株的抗菌活性上级优于泰利霉素(2)。在2058位具有A→T突变的金黄色葡萄球菌(E.大肠杆菌编号)。
There is an urgent need to discover new drugs to address the pressing problem of antibiotic-resistance. Macrolide antibiotics such as erythromycin (1) are safe, broad-spectrum antibiotics used in the clinic since 1954. Herein we report the synthesis and evaluation of 4,8,10-tridesmethyl telithromycin (3), a novel desmethyl analogue of the 3rd-generation drug telithromycin (2), which is a semisynthetic derivative of 1. Analogue 3 was found to possess antibiotic activity and was superior to telithromycin (2) when tested against resistant strains of S. aureus possessing an A→T mutation at position 2058 (E. coli numbering).
