The first antibiotics with low nanomolar activity against the multidrug-resistant Mycobacterium abscessus are achieved by rational redesign of rifamycins. Structure-based modification on the rifamycin ansa-chain, together with microbiological, biochemical, biophysical and in vivo characterizations, provides novel candidates that are 300-fold more active than rifampicin, completely bypass the resistance
通过合理重新设计利福霉素,获得了第一种针对多重耐药脓肿分枝杆菌具有低纳摩尔活性的抗生素。对利福霉素ansa链进行基于结构的修饰,结合微生物学、生物化学、生物物理和体内表征,提供了比利福平活性高 300 倍、完全绕过耐药性并具有有前途的药代动力学特征的新型候选药物。
