Pyrazinoic acid, the active form of the first-line antituberculosis drug pyrazinamide, decreased the proton motive force and respiratory ATP synthesis rates in subcellular mycobacterial membrane assays. Pyrazinoic acid also significantly lowered cellular ATP levels in Mycobacterium bovis BCG. These results indicate that the predominant mechanism of killing by this drug may operate by depletion of cellular ATP reserves.
吡嗪酸是一线抗结核药物吡嗪酰胺的活性形式,它降低了亚细胞分枝杆菌膜测定中的质子动力势和呼吸 ATP 合成率。吡嗪酸还显著降低了牛分枝杆菌卡介苗中的细胞 ATP 水平。这些结果表明,这种药物的主要杀菌机制可能是通过耗尽细胞 ATP 储备来实现的。
