Nadifloxacin
Based on 1 publication(s) in Google Scholar
Nadifloxacin (OPC7251) is a broad-spectrum quinolone antibiotic. Nadifloxacin inhibits bacterial DNA gyrase and topoisomerase IV, interfering with DNA replication. It also suppresses the production of proinflammatory cytokines (such as IL-1α, IL-6, and IL-8). Nadifloxacin exhibits antibacterial activity against various pathogens, including Propionibacterium acnes and Staphylococcus aureus. Nadifloxacin also exhibits anti-inflammatory activity. Nadifloxacin can be used in the research of skin infections such as acne vulgaris, folliculitis, and impetigo.

IL-1α |
Nadifloxacin shows potent activity against Propionibacterium acnes isolated from acne vulgaris, with MIC90 of 0.39 µg/mL[1].
Nadifloxacin shows activity against clinical isolates of Propionibacterium acnes, Propionibacterium granulosum, Staphylococcus aureus and coagulase-negative staphylococci, with MIC50s of 0.25, 0.125, 0.03, 0.06 mg/L, respectively[3].
Nadifloxacin (3-30 μg/mL; up to 24 h) inhibits the production of IL-12 and IFN-γ by human peripheral blood mononuclear cells stimulated with heat-killed Propionibacterium acnes, and also inhibits the production of IL-1α, IL-6, IL-8 and GM-CSF by human epidermal keratinocytes treated with IFN-γ plus IL-1β[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Nadifloxacin (7.4 mg/kg; topical application) reaches detectable cutaneous concentrations in the dorsal skin of male SD rats, with concentrations of 82.3 μg/g wet tissue at 4 h and 6.7 μg/g wet tissue at 24 h[4].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.94 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
