Levofloxacin sodium is an orally active broad-spectrum antibacterial agent with antioxidant and antibacterial activities. Levofloxacin sodium upregulates TC synthesis-related genes and transport-related genes, reduces plasma PCSK9, inhibits GABA_A receptors and mitochondrial complexes I/III, scavenges hydroxyl radicals and neutrophil-derived ROS, and inhibits NO metabolites and interferon-γ. Levofloxacin sodium improves survival, alleviates lung injury, and reduces oxidative and inflammatory markers in influenza virus-infected mice. Levofloxacin sodium inhibits lung cancer proliferation and xenograft tumor growth, and induces apoptosis and oxidative stress. Levofloxacin sodium can be used in research on bacterial infection, influenza virus infection, atherosclerosis, and lung cancer.

Description

All Topoisomerase Isoforms :

In Vitro

Anti-cancerApoptosisBacterial InfectionInnate ImmunityLipid MetabolismMitochondrial FunctionMitochondrial Oxidative PhosphorylationOxidative Stress

Anti-cancer

Levofloxacin (50-200 mg/mL; 72 h) sodium inhibits the proliferation of A549, H3255, NCL-H69, and H460 lung cancer cells^[4].

Anti-cancer

Apoptosis

Levofloxacin (50-200 mg/mL; 72 h) sodium induces Annexin V-positive apoptosis in A549, H3255, NCL-H69, and H460 cells^[4].

Bacterial Infection

Levofloxacin sodium shows MIC50 values of 1.0, 0.5, and 0.25 μg/mL against the susceptible Mycobacterium tuberculosis strains OFLO, LVFX, and SPFX, respectively^[4].

Innate Immunity

Lipid Metabolism

Levofloxacin (LEV) (0.05-0.2 mg/mL; 24 h) sodium reduces ox-LDL-induced foam cell formation in Raw264.7 macrophages and decreases oleic acid-induced lipid deposition in HepG-2 cells^[2].

Mitochondrial Function

Mitochondrial Oxidative Phosphorylation

Levofloxacin (50-200 µg/mL; 24 h) sodium reduces basal and maximal mitochondrial respiration and decreases ATP levels in A549 and H460 cells; it inhibits mitochondrial ETC complexes I and III, but not complexes II and IV; it increases intracellular ROS, mitochondrial superoxide, and extracellular hydrogen peroxide^[4].

Oxidative Stress

Levofloxacin (20-200 μM; 30 s) sodium scavenges hydroxyl radicals generated by H₂O₂/UV in cell-free DMPO ESR experiments, and 200 μM is sufficient to inhibit the DMPO-OH signal^[1].

Oxidative Stress

Innate Immunity

Levofloxacin (50-1000 μM; 7 min) sodium scavenges PMA-stimulated mouse neutrophil-derived ROS in the DMPO ESR assay, requiring 1000 μM to achieve a significant reduction^[1].

Anti-cancerApoptosisOxidative StressLipid MetabolismViral InfectionCytokines & ChemokinesOthers

Anti-cancer

Apoptosis

Oxidative Stress

Levofloxacin (100 mg/kg; intraperitoneal injection) sodium inhibits H460 lung cancer growth in SCID mice, reduces tumor volume and weight, and simultaneously decreases proliferation and increases apoptosis and oxidative stress markers^[4].

Lipid Metabolism

Levofloxacin sodium reduces aortic lipid deposition and plasma lipids in high-fat diet ApoE^-/- mice and upregulates hepatic lipoprotein receptors and cholesterol transport genes, with minimal effect on DGAT1/MTTP-related TG synthesis and VLDL secretion^[2].

Viral Infection

Oxidative Stress

Cytokines & Chemokines

Levofloxacin (25-100 mg/kg; intraperitoneal injection; once daily; days 2-6) sodium improves the survival rate of PR8 influenza-infected mice, alleviates lung histological injury, oxidative/nitrative stress, and NOx/IFN-γ levels in BALF, without reducing pulmonary viral titers^[1].

Others

Levofloxacin (10-40 mg/kg; intraperitoneal injection; single administration) sodium produces anxiety-like effects in the rat elevated plus maze test; shortens sedative-hypnotic-induced sleep duration without affecting sleep latency; reduces acetic acid-induced writhing responses and prolongs hot plate latency^[3].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
