| Additional Infomation |
Rosoxacin is a quinolone monocarboxylic acid with the structure 1,4-dihydroquinolone-3-carboxylic acid, substituted with an ethyl group at position 1 and a pyridin-4-yl group at position 7. It is an antibacterial drug effective against Neisseria gonorrhoeae and has been used to treat urinary tract infections and certain sexually transmitted diseases. It is both an antibacterial and anti-infective agent. Rosoxacin belongs to the quinolone antibiotic class, quinolone monocarboxylic acid class, and pyridine class of compounds. Rosoxacin is a quinolone derivative antibiotic used to treat bacterial infections of the respiratory tract, urinary tract, gastrointestinal tract, central nervous system, and in immunocompromised patients. Rosoxacin is effective against penicillin-resistant strains and is a single-dose oral medication, avoiding all the complications of parenteral penicillin administration, especially anaphylactic shock.
Drug Indications For the treatment of bacterial infections of the respiratory tract, urinary tract, gastrointestinal tract, central nervous system, and in immunocompromised patients. Mechanism of Action Rosoxacin binds to and inhibits the activity of topoisomerase II (DNA gyrase) and topoisomerase IV, both of which are essential for bacterial DNA replication, transcription, repair, and recombination. Pharmacodynamics Rosoxacin is a non-fluoroquinolone antibiotic. Its mechanism of action is to block bacterial DNA replication by binding to DNA gyrase, thereby preventing the unwinding of the DNA double helix and allowing one DNA double helix to replicate into two. Rosoxacin is a broad-spectrum antibiotic effective against both Gram-positive and Gram-negative bacteria. |

| Solubility (In Vitro) |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (7.07 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (7.07 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution 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 stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
