| Description | (Rac)-Moxifloxacin ((Rac)-BAY 12-8039 free base) is an isomer of Moxifloxacin Hydrochloride. Moxifloxacin Hydrochloride (BAY 12-8039) is an orally effective 8-methoxyquinolone antibacterial agent used in studies on acute bacterial sinusitis, acute bacterial exacerbations of chronic bronchitis, and infectious pneumonia. |
| In vitro | Moxifloxacin hydrochloride (BAY 12-8039) was evaluated for its in vitro activity against Listeria monocytogenes using a bone marrow-derived mouse macrophage model. Time-kill curves and intracellular growth inhibition assays compared it with amoxicillin. Moxifloxacin acted more rapidly, beginning its effect within the first 3 hours and achieving complete broth sterilization within 24 hours of incubation. It also seemed to protect macrophages from lysis, as many cells survived after 24 hours of incubation. |
| In vivo | Moxifloxacin (BAY 12-8039; 12 mg/kg; intravenous injection; administered once to three times daily over 7 days; in male Wistar rats) extends survival when administered every 8 hours. Tissue cultures taken 30 hours after bacterial challenge reveal significantly reduced bacterial overgrowth in the spleen and lungs of moxifloxacin-treated animals compared to saline-treated ones, with no observed toxicity. |
