Cefathiamidine is a first-generation cephalosporin antibacterial agent and is used to treat infections caused by susceptible bacteria. Cefathiamidine exhibits a wide spectrum of antimicrobial activity against bacteria. Cefathiamidine is used for the treatment of respiratory, liver, five senses, urinary tract infections, endocarditis and sepsis[1][2].
The in-vitro activity of Cefathiamidine against Streptococcus faecalis and Streptococcus faecium are studied in comparison with other β-lactams. All the 56 strains of Str. faecalis tested are inhibited by 2 mg/L of Cefathiamidine. The MBCs of Cefathiamidine and Ampicillin for ten strains of Str. faecalis show that the ratios of MBC/MIC are greater than 64. The rates of killing of Str. faecalis are reduced at concentrations of Cefathiamidine and Ampicillin greater than the MIC. The most rapid killing is obtained at 2 mg/L Cefathiamidine or 4 mg/L of Ampicillin. With the addition of 1 mg/L gentamicin this paradoxical bacteriocidal effect is eliminated. Time killing studies show99.9% of the cells are killed within 6 hours by a combination of aminoglycoside and β-lactam[2].
Cefathiamidine is not absorbed orally and is, thus, administered through the parenteral route (intravenously or intramuscularly). Cefathiamidine is widely distributed in most bodily fluids and tissues; however, Cefathiamidine cannot pass through the blood-brain barrier. The protein-binding capacity of Cefathiamidine is 23%, and more than 90% of Cefathiamidine is excreted unchanged by the kidney[1].

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. |

Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid 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 master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
