ln Vitro |
Cefotiam hydrochloride (SCE-963; 0-6.25 μg/mL; 8 h) has antibacterial activity against P. mirabilis IFO 3849, with a minimum inhibitory concentration (MIC) of 1.56 μg/mL [1]. Highly effective against Staphylococcus aureus and Staphylococcus aureus is cefotiam (SCE-963; 0-6.25 μg/mL; 8 h) hydrochloride. Both Staphylococcus aureus (27 strains, MIC values 0.5–1 μg/mL) and Staphylococcus aureus. albus (8 strains, MIC 0.25–0.5 μg/mL) are present. All 29 hemolytic streptococcus strains, 9 pneumococci strains, and 6 viridans streptococci strains had minimum inhibitory concentrations (MICs) between 0.06-4 μg/mL [2].

ln Vivo |
Mice with urinary tract infections caused by Proteus mirabilis can be treated with cefotiam hydrochloride (SCE-963; 12.5-800 mg/kg; intravenously; twice daily for 5 days), which reduces or eradicates the bacterium in the kidneys and bladder wall [1].

Additional Infomation |
Cefotiam is a cephalosporin with ({1-[2-(dimethylamino)ethyl]-1H-tetrazol-5-yl}sulfanyl)methyl and (2-amino-1,3-thiazol-4-yl)acetamido substituents at positions 3 and 7, respectively, of the cephem skeleton. A third generation beta-lactam cephalosporin antibiotic, it is active against a broad spectrum of both Gram positive and Gram negative bacteria. It has a role as an antibacterial drug. It is a cephalosporin, a semisynthetic derivative and a beta-lactam antibiotic allergen.
One of the cephalosporins that has a broad spectrum of activity against both gram-positive and gram-negative microorganisms. Cefotiam has been reported in Bos taurus with data available. Cefotiam is a third-generation, semi-synthetic, beta-lactam cephalosporin antibiotic with antibacterial activity. Cefotiam binds to penicillin-binding proteins (PBPs), transpeptidases that are responsible for crosslinking of peptidoglycan. By preventing crosslinking of peptidoglycan, cell wall integrity is lost and cell wall synthesis is halted. One of the CEPHALOSPORINS that has a broad spectrum of activity against both gram-positive and gram-negative microorganisms. Drug Indication For treatment of severe infections caused by susceptible bacteria. Mechanism of Action The bactericidal activity of cefotiam results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins (PBPs). Pharmacodynamics Cefotiam is a third generation beta-lactam cephalosporin antibiotic that works by inhibiting bacterial cell wall biosynthesis. It is a broad spectrum antibiotic that is effective against Gram positive and Gram negative bacteria. |

Solubility in Formulation 1: ≥ 2.5 mg/mL (4.18 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (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 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 (4.18 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (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 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*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.
