Cephalothin sodium
Based on 3 publication(s) in Google Scholar
Cephalothin (Cephalotin) sodium is a semi-synthetic cephalosporin antibiotic and beta-lactam antibiotic. Cephalothin inhibits class C β-lactamase AmpC, with an Ki of 0.32 µM. Cephalothin sodium binds to penicillin-binding proteins, interfering with the cross-linking of peptidoglycan in the cell wall and thus hindering the normal synthesis of the bacterial cell wall. Cephalothin sodium shows antibacterial activity against a variety of bacteria. Cephalothin sodium can be used in hematological and nephrotoxicity studies.

β-lactam |
Liposome-encapsulated Cephalothin sodium kill bacteria in macrophages infected with Salmonella typhimurium[2].
Cephalothin (1.6-12.5 mM) sodium inhibits ADP-induced shape change, aggregation and release reactions in human citrated platelet-rich plasma[4].
Cephalothin (18 h) sodium is less active than Cefamandole (HY-B1128) against Staphylococcus aureus and less active than Cefamandole or Cefoxitin (HY-B1825) against Haemophilus influenzae[7].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Cephalothin (200-800 mg/kg per day; s.c.; per day; 10 days) sodium has a significant protective effect against Gentamicin (HY-A0276A)-related nephrotoxicity in rats when given simultaneously with Gentamicin (HY-A0276A)[6].
Cephalothin (i.m.; 1.0 and 3.5 h post-infection) sodium is less effective than BL-S786 and Cefamandole in protecting mice from lethality in experimental infections caused by Enterobacteriaceae[7].

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 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.97 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 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (5.97 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.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
