Flumequine (R-802) is a quinolone antibiotic, and acts as a topoisomerase II inhibitor, with an IC50 of 15 μM (3.92 μg/mL).
Flumequine (R-802) is a topoisomerase II inhibitor, with an IC50 of 3.92 μg/mL, and less potently inhibits Gyrase, with an IC50 of 1764 μg/mL. Flumequine (0-625 μg/mL) increases migration of nuclear DNA from CHL cells[1]. Flumequine (R-802) inhibits Spanish field isolates of B. hyodysenteriae with MIC50 and MIC90 of 50 and 100 μg/mL, and MBC50 and MBC90 of 50, 200 μg/mL, respectively[2]. Flumequine (R-802) suppresses A. salmonicida isolates with MIC ranging from 0.06 to 32 μg/mL[3].
Flumequine (R-802) (0-500 mg/kg, p.o.) causes dose-related DNA damage in the stomach, colon, and urinary bladder of mice, 1 and 3 h but not 24 h after its administration[1].
