Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC50/Ki
Topoisomerase IV [2]
In vitro

Ciprofloxacin is a fluoroquinolone antibiotic, shows MIC90 (minimal inhibitory concentrations for 90%) of between 0.008 and 2 μg/ml for Enterobacteriaceae, Pseudomonas aeruginosa, Haemophilus influenzae, Neisseria gonorrhoeae, streptococci, Staphylococcus aureus, and Bacteroidesfragilis strains. [1] This compound inhibits topoisomerase IV as a primary topoisomerase target and gyrase as a secondary target. [2] It shows an AUC (area under the curve) of 24 μg×h/ml[3]
