      An oxazinoquinoline that is 2,3-dihydro-7H-[1,4]oxazino[2,3,4-ij]quinolin-7-one substituted by methyl, carboxy, fluoro, and 4-methylpiperazin-1-yl groups at positions 3, 6, 9, and 10, respectively. ChEBI CHEBI:194135
      An oxazinoquinolone carrying carboxy, fluoro, methyl and 4-methylpiperazino substituents. A synthetic fluoroquinolone antibacterial agent, it inhibits the supercoiling activity of bacterial DNA gyrase , halting DNA replication.

      Ofloxacin is a fluoroquinolone whose primary mechanism of action is inhibition of bacterial DNA gyrase.;Target: DNA gyrase Ofloxacin is a fluoroquinolone whose primary mechanism of action is inhibition of bacterial DNA gyrase. In vitro it has a broad spectrum of activity against aerobic Gram-negative and Gram-positive bacteria, although it is poorly active against anaerobes [1]. Ofloxacin, like other 4-quinolones, is unusual among front line drugs available to treat bacterial infections since it affects bacterial DNA synthesis, rather than cell wall or protein synthesis [2].Ofloxacin (20 mg/kg), norfloxacin (40 mg/kg), pefloxacin mesylate dihydrate (40 mg/kg)and ciprofloxacin (50 mg/kg) were administered by gavage twice daily for three consecutive weeks. 6 weeks after treatment, the test animals were euthanised and Achilles tendon specimens were collected. A computer monitored tensile testing machine was utilised for biomechanical testing. The mean elastic modulus of the control MedChem Express HY-B0125
