Quinolone |
Temafloxacin (0-64 µg/mL; 18-24 h) shows good antibacterial activity for gram-positive/negative bacteria, with MIC ranges of <0.004-0.5, 0.5-2 and 0.06-0.25 µg/mL for E. coli, P. aeruginosa, and S. aureus, respectively[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:E. coli (16 strains), P. aeruginosa (13 strains), and S. aureus (17 strains).
-
Concentration:0-64 µg/mL
-
Incubation Time:18-24 h
-
Result:Inhibited E. coli (16 strains), P. aeruginosa, and S. aureus with MIC ranges of <0.004-0.5 (MIC 90%=0.06, =0.06), 0.5-2 (MIC 90%=1, MIC 50%=1) and 0.06-0.25 µg/mL (MIC 90%=0.125, MIC 50%=0.125). MIC 90% and 50% means MIC for 90% and 50% of the isolates (unit: µg/mL).

Solvent & Solubility
DMSO : < 1 mg/mL (insoluble or slightly soluble)
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.
