Cefonicid monosodium
Cefonicid monosodium is a long-acting cephalosporin antibiotic. Cefonicid monosodium is also a non-competitive type I β-lactamase with a Ki value of 0.8 μM. Cefonicid monosodium exhibits broad-spectrum antibacterial activity and is effective against a variety of Gram-positive and Gram-negative bacteria. Cefonicid monosodium binds PBP1a, PBP1b, and PBP3, inhibiting peptidoglycan synthesis and leading to filamentation and lysis. Cefonicid monosodium can be used for research on infections.

In Vitro
Cefonicid (0-24 h) monosodium exhibits concentration-dependent bactericidal activity against Klebsiella pneumoniae strain 2603 in vitro, with an MIC of 0.25 mg/L[3].
Cefonicid monosodium binds to PBPs of E. coli K-12 KN-126, with the highest affinity for PBP 1a, followed by PBP 3, and does not significantly bind PBP 5 or 6[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
Cefonicid (40 mg/kg; single dose) monosodium exhibits excellent protective efficacy against S. aureus, E. coli, P. mirabilis, and K. pneumoniae infections in mice[4].
Cefonicid monosodium has excellent prophylactic protective efficacy against surgical wound infections in mice, with an ED50 value of ≤2.1 mg/kg against Gram-negative bacilli and an ED50 value of 3.7 to 8.7 mg/kg against S. aureus[4].
