Grepafloxacin (OPC-17116; 0-1 mg/L; 14-21 d) has antibiotic activity with a MIC value of ≤ 0.006 mg/L for E. coli strain[1].
Grepafloxacin (0-1 mg/L; 3 h) has antimicrobial activity against mycobacteria in macrophages with a MIC value of 0.5 mg/L for M. avium[1].
Grepafloxacin exhibits potent in vitro antibacterial activity against Gram-positive bacteria such as Streptococcus pneumoniae and high in vivo efficacy on the experimental systemic infections caused by the Gram-positive and -negative bacteria tested[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Grepafloxacin (25-200 mg/kg; p.o.; 5 days/week for 4 weeks; female C57BL6/J-Lyst bg-J/ mice/beige mice) has modest activities in both intranasal (IN) infection and intravenous (IV) Mycobacterium avium infection models[3].
