生物活性:
Fidaxomicin (OPT-80), a macrocyclic antibiotic, is an orally active and potent RNA polymerase inhibitor. Fidaxomicin has a narrow spectrum of antibacterial activity and a good anti-Clostridium difficile activity (MIC90=0.12?μg/mL). Fidaxomicin can be used for Clostridium difficile infection (CDI) research.
体内研究:
Fidaxomicin (0-5 mg/kg, Orally, once a day for 5 days) completely prevents the lethality of the animals and prevents the occurrence of relapses in a hamster model for pseudomembranous colitis.Animal Model:Male Golden Syrian hamsters (80-100 g, Hamster model for pseudomembranous colitis)
Dosage:0.2, 1, and 5 mg/kg
Administration:Orally, once a day for 5 days, beginning 8 h after infection
Result:Completely prevented the lethality of the animals. Completely prevented the development of antibiotic-induced C. difficile colitis in hamsters at doses as low as 0.2 mg/kg.
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.Fidaxomicin is not inhibitory to commonly cultured bowel commensals (MIC90 >1024?μg/mL).
