Purity: ≥98%
Ceftazidime hydrate (Fortaz; Fortum; GR20263; LY-139381; GR-20263), the hydrated form of Ceftazidime, is a 3rd generation, broad-spectrum β-lactam antibiotic/cephalosporin antibiotic useful for the treatment of a number of bacterial infections.
| Targets |
β-lactam
|
|---|---|
| ln Vitro |
Antibacterial and anti-biofilm properties against P. aeruginosa strains are demonstrated by ceftazidime (0-8 µg/mL, approx., 24 h) pentahydrate[2].
Ceftazidime pentahydrate (0–40 µg/mL, approximately; 18–20 h) exhibits inhibitory effects on isolates of S. maltophilia[3]. |
| ln Vivo |
In a murine thigh infection model, ceftazidime (2 h infusion of injection, 2 000 mg, every 8 h for 24 h) pentahydrate moderately reduces bacterial density[4].
|
| Cell Assay |
Cell Line: P. aeruginosa strains (PAO1, PA1, PA2)
Concentration: 0-8 µg/mL approximately Incubation Time: 24 h Result: demonstrated MIC values of 2-4 µg/mL for antibacterial and anti-biofilm activities. |
| Animal Protocol |
Animal Model: Murine thigh infection model[4]
Dosage: 2000 mg Administration: 2 h infusion of injection, every 8 h for 24 h. Result: decreased bacterial density when compared to the isogenic strain of NDM (New Delhi metallo-β-lactamase). |

| Solubility (In Vitro) |
DMSO : 2~100 mg/mL (3.65~157.07 mM)
Water : ~25 mg/mL |
|---|---|
| Solubility (In Vivo) |
Solubility in Formulation 1: 2.5 mg/mL (3.93 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 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: ≥ 2.5 mg/mL (3.93 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 25.0 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.) |

| 10 mM | 0.1830 mL | 0.9148 mL | 1.8296 mL |
*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.
