Ceftolozane sulfate
Based on 2 publication(s) in Google Scholar
Ceftolozane (CXA-101) sulfate is an antipseudomonal cephalosporin. Ceftolozane binds to P. aeruginosa essential PBPs (1b, 1c, 2 and 3) with high affinity. Ceftolozane inhibits cell wall synthesis by binding the PBPs. Ceftolozane sulfate inhibits P. aeruginosa and Enterobacteriaceae.

Biological Activity
MIC: 0.5 μg/mL (P. aeruginosa PAO1)[1]
Ceftolozane sulfate shows antibacterial activity against fully AmpC-derepressed P. aeruginosa, with MIC of 4 mg/L[4].
Ceftolozane sulfate (≤0.12->64 μg/mL) shows antipseudomonal activity, including against carbapenem-resistant and MDR isolates, with MICs of >8 μg/mL for 11 carbapenem-resistant P. aeruginosa isolates (4.7%)[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Ceftolozane (180 mg/kg, s.c., every 8 h, 48 h) sulfate reduces bacterial load and improves early pulmonary inflammatory response without impairing 48 h post-infection homeostasis in a mice model of Pseudomonas aeruginosa acute pneumonia[7].

Solvent & Solubility
DMSO : 50 mg/mL (65.38 mM; ultrasonic and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 10 mg/mL (13.08 mM; Need ultrasonic)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

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 (3.27 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.
