Pefloxacin-d3

Pefloxacin-d3 (Pefloxacinium-d3) is the deuterium labeled Pefloxacin. Pefloxacin (Pefloxacinium) is a broad spectrum antibiotic. Pefloxacin blocks DNA replication by inhibiting DNA gyrase. Pefloxacin inhibits DNA relaxation catalyzed by topoisomerase I with an IC50 of 45 μg/mL. Pefloxacin exhibits antibacterial activity against Escherichia coli, Pseudomonas aeruginosa, and Bacteroides fragilis with MIC90s of 0.12, 4, and 16 mg/L, respectively. Pefloxacin has anti-Plasmodium yoelii infection activity. Pefloxacin increase UVA-induced edema and immunesuppression. Pefloxacin can be used for infection studies[1][2][3][4][5][6][7][8][9].
