Fidaxomicin 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].
体内研究

Administering Fidaxomicin orally (0-5 mg/kg, once daily for five days) effectively protects against death and relapse in a hamster model of pseudomembranous colitis[3].

体外研究

Fidaxomicin selectively eradicates pathogenic Clostridium difficile with minimal disruption to the multiple species of bacteria that make up the normal, healthy intestinal flora[1].

Fidaxomicin demonstrates no inhibitory effect on the common gut commensals, with a MIC90 exceeding 1024 μg/mL[2].
