抗生素耐药性的传播速度快于将新化合物引入临床实践的速度,导致公共卫生危机。大多数抗生素都是通过筛选土壤微生物来生产的,但这种有限的可培养细菌资源在20世纪60年代被过度开采。生产抗生素的合成方法无法取代这一平台。未培养的细菌约占外部环境中所有物种的99%,是新抗生素的未开发来源。我们开发了几种方法,通过使用特定的生长因子原位培养未培养的生物体。在这里,我们报告了一种新的抗生素,我们称之为teixobactin,在未培养的细菌筛选中发现。Teixobactin通过与脂质II(肽聚糖的前体)和脂质III(细胞壁磷壁酸的前体)的高度保守基序结合来抑制细胞壁合成。我们没有获得任何对替沙菌素耐药的金黄色葡萄球菌或结核分枝杆菌突变株。这种化合物的特性表明了开发抗生素的途径,这些抗生素可能会避免耐药性的发展。
Antibiotic resistance is spreading faster than the introduction of new compounds into clinical practice, causing a public health crisis. Most antibiotics were produced by screening soil microorganisms, but this limited resource of cultivable bacteria was overmined by the 1960s. Synthetic approaches to produce antibiotics have been unable to replace this platform. Uncultured bacteria make up approximately 99% of all species in external environments, and are an untapped source of new antibiotics. We developed several methods to grow uncultured organisms by cultivationin situor by using specific growth factors. Here we report a new antibiotic that we term teixobactin, discovered in a screen of uncultured bacteria. Teixobactin inhibits cell wall synthesis by binding to a highly conserved motif of lipid II (precursor of peptidoglycan) and lipid III (precursor of cell wall teichoic acid). We did not obtain any mutants ofStaphylococcus aureusorMycobacterium tuberculosisresistant to teixobactin. The properties of this compound suggest a path towards developing antibiotics that are likely to avoid development of resistance.
