Quinolone

 

In Vitro

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].

Cell Assay
[1]

The Chinese hamster lung cell line CHL/IU is routinely maintained in monolayer culture in Dulbecco's modified MEM medium supplemented with 10% fetal bovine serum at 37°C under a 5% CO2 atmosphere. Exponentially growing cells are treated with Flumequine (R-802) dissolved in DMSO for 1 h. The dose range is chosen in order to obtain both damaged and highly damaged cells. Following Flumequine (R-802) treatment, cells are embedded in GP42 agarose dissolved in saline at 1%. Cell number and cell viability are determined for each dose[1].

Animal Administration
[1]

Infant and young-adult male ddY mice at 4 and 7 weeks of age, respectively, are used after 1 week of acclimatization. Groups are treated once orally with Flumequine (R-802) at <500 mg/kg. Adult mice are sacrificed at 3 and 24 h after treatment, and 8 organs, the stomach, colon, liver, kidney, urinary bladder, lung, brain, and bone marrow, are removed. Infant mice are sacrificed 3 and 24 h after treatment, and the livers are excised. In another study, the genotoxicity of Flumequine (R-802) is studied in the regenerating liver of adult mice. For this purpose, male mice at 8 weeks-of-age are anesthetized with ether and 3 major lobes of the liver, left lateral lobe, left medial lobe, and right lateral lobe, are removed. Four days after the hepatectomy, mice are subjected to oral administration of Flumequine (R-802) once. They are sacrificed 3 h after FL-treatment and regenerated livers are sampled. Slides for the comet assay are prepared at each set time[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
