PNAS:解偶联剂或可用于对抗超级细菌

伊利诺伊大学化学家组成的研究人员最近得出研究结论:一些用于治疗寄生虫感染和癌症的药物也可以改装用于治疗葡萄球菌和肺结核感染。研究结果发表在《美国国家科学院院刊》。研究人员认为,通过多角度多方面研究靶细菌的特点,它们更不易出现耐药性。 研究负责人Eric Oldfield教授认为,我们现在有超级细菌足以对目前的药物产生完全耐药性,  有一种叫解偶联剂的药物用于治疗寄生虫感染。它主要是通过破

伊利诺伊大学化学家组成的研究人员最近得出研究结论:一些用于治疗寄生虫感染和癌症的药物也可以改装用于治疗葡萄球菌和肺结核感染。研究结果发表在《美国国家科学院院刊》。研究人员认为,通过多角度多方面研究靶细菌的特点,它们更不易出现耐药性。 


研究负责人Eric Oldfield教授认为,我们现在有超级细菌足以对目前的药物产生完全耐药性, 
有一种叫解偶联剂的药物用于治疗寄生虫感染。它主要是通过破坏细胞的能量供应系统,引发细胞死亡。研究人员也致力于研究这些药物是否可以用于治疗其他疾病如糖尿病等。 

由于现在迫切需要研制出新型抗生素,因此研究人员试图探究利用解偶联剂以杀灭细菌。
研究人员发现,许多解偶联剂药物已经得到FDA的批准。不仅如此,研究人员发现许多FDA批准的解偶联剂可杀死细菌。它们可抑制细菌的酶活性,或影响细胞膜和细胞壁功能进而使细菌失去活性。 

Vacquinol是一种正在开发的药物,其主要用途是治疗脑胶质母细胞瘤,研究人员发现,这种药物可作为解偶联剂抑制结核杆菌酶活性,中断其能量供应而导致细菌死亡。进一步探究后,研究人员发现了与vacquinol具有相似结构的化合物都能够抑制结核杆菌和金黄色葡萄球菌。 

研究人员现在探究通过使解偶联剂化合物在细菌细胞内代谢,以达到减少它们对机体细胞的损伤,同时可迅速杀灭细菌的效果。但是研究人员并不知道这些化学物的衍生物是否对机体有害,因此他们需要更多更复杂的实验来进一步探究。
