Description and Uses

Cefalothin is a β-lactam cephalosporin antibiotic. It inhibits the growth of various Gram-positive and Gram-negative bacteria, including several strains of S. pyogenes, S. aureus, C. tetani, N. gonorrhoeae, Salmonella, and Shigella (MICs = 0.1-0.2, 0.312-0.625, 0.078, 1.25, 1.56-6.25, and 3.12-12.5 μg/ml, respectively). Cefalothin binds to E. coli penicillin-binding proteins (PBPs; IC₅₀s = <0.25, 16, 37, and 1 μg/ml for PBP1a, 1bs, 2, and 3, respectively, in a radioligand binding assay), which interferes with bacterial morphogenesis. It exhibits antibacterial activity in mouse models of infection with S. pyogenes, D. pneumoniae, and S. aureus. Formulations containing cefalothin were previously used in the prophylaxis and treatment of bacterial infections.
