生物活性
描述 Fidaxomicin (OPT-80), identified as a macrocyclic antibiotic, acts as a potent inhibitor of RNA polymerase when taken orally. It exhibits a narrow antibacterial spectrum, notably showing strong activity against Clostridium difficile (MIC90=0.12 μg/mL), making it valuable for research into Clostridium difficile infections (CDI)[1].[2].[3].
