Cephalothin
Based on 3 publication(s) in Google Scholar
Cephalothin (Cephalotin) 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 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 shows antibacterial activity against a variety of bacteria. Cephalothin can be used in hematological and nephrotoxicity studies.

Liposome-encapsulated Cephalothin kill bacteria in macrophages infected with Salmonella typhimurium[2].
Cephalothin (1.6-12.5 mM) inhibits ADP-induced shape change, aggregation and release reactions in human citrated platelet-rich plasma[4].
Cephalothin (18 h) 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) 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) 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 (6.31 mM); Clear solution
