Cefotaxime is a third-generation cephalosporin antibiotic with broad-spectrum antibacterial activity. It is most commonly prescribed for the treatment of infectious diseases induced by Gram-positive or Gram-negative bacteria[1].
Cefotaxime (200, 400, 600, or 1000μg/mL; 24h) significantly promotes ROS generation in HT1080 cells[1]. Cefotaxime (0.02-2µg/ml, 5h) combined with Mecillinam could eliminate both cephalosporin-resistant bacteria harbouring CTX-M-15WT and mecillinam-resistant bacteria harbouring the mutant CTX-M-15N135D, thereby constraining resistance evolution of β-lactamase CTX-M-15[2].
Cefotaxime (200 or 400mg/kg/8h, 9 injections, subcutaneous injection) significantly increased bacterial clearance from the pneumonia model in leukopenic mice[3]. Cefotaxime (100mg/kg/4h, 24h, subcutaneous injections) combined with Amoxicillin-Clavulanate significantly reduces bacterial counts and achieves kidney sterilization in in a Murine Urinary Tract Infection Model[4].

| Cell experiment [1]: | |
Cell lines | Human fibrosarcoma HT1080 cells |
Preparation Method | HT1080 cells were seeded on glass plates and treated with the indicated concentrations (200, 400, 600, or 1000μg/mL) of Cefotaxime for 24h. After stimulation, cells were treated with 10µM DCFH-DA for 30min at 37°C. After washing with PBS, the intracellular ROS generation was observed under laser confocal microscope. |
Reaction Conditions | 200, 400, 600, or 1000μg/mL; 24h |
Applications | Cefotaxime significantly promotes ROS generation in HT1080 cells. |
| Animal experiment [2]: | |
Animal models | Pneumonia model in leukopenic mice |
Preparation Method | Amoxicillin (AMO) and Cefotaxime (CTX) were administered at 8-h intervals with a total of nine injections, and Ceftriaxone (CRO) was given at 12-h intervals with a total of six injections. The dose of each antibiotic varied with the infective strain. Mice infected with strain P40422 were treated with AMO or CTX at 200 or 400mg/kg or with CRO at 100mg/kg. Mice infected with P40984 were treated with AMO at 200 or 400mg/kg, CTX at 400mg/kg, or CRO at 100 or 200mg/kg. Each dose was administered subcutaneously (s.c.) in 0.5ml of sterile water. Control animals received the same volume of isotonic saline. |
Dosage form | 200 or 400mg/kg/8h, 9 injections, subcutaneous injection |
Applications | Cefotaxime significantly increased bacterial clearance from the pneumonia model in leukopenic mice. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
