two series of novel cephalosporins that are bactericidal to Mycobacterium tuberculosis alone of the pathogens tested, which only kill M. tuberculosis when its replication is halted by conditions resembling those believed to pertain in the host, and whose bactericidal activity is not dependent upon or enhanced by clavulanate, a β-lactamase inhibitor. The two classes of cephalosporins bear an ester or
我们报告了两个系列的新型头孢菌素,它们仅对所测试的病原体具有结核分枝杆菌的杀菌作用,仅当其复制因类似于宿主的条件而中止繁殖,且其杀菌活性不依赖于或不依赖于结核分枝杆菌时才杀死结核分枝杆菌可以通过β-内酰胺酶抑制剂克拉维酸增强。这两类头孢菌素在头孢菌素环系统的C-2处带有一个酯或另一种恶二唑异戊二烯,该位置在该类临床使用的药物中几乎完全是羧酸。该系列的代表杀死巨噬细胞内的结核分枝杆菌,而对巨噬细胞或其他哺乳动物细胞无毒性。
