Moxalactam (sodium salt)

Moxalactam (Latamoxef) sodium salt is a synthetic oxa-β-lactam antibiotic. Moxalactam sodium salt has a broad spectrum of activity against Gram-positive and Gram-negative aerobic and anaerobic bacteria. Moxalactam sodium salt inhibits production of β-lactamases^[1]. IC50 & Target:β-lactamases^[1] In Vitro: Moxalactam (Latamoxef) inhibits 90% of strains of Escherichia coli, Klebsiella species, Proteus species, Morganella morganii, Neisseria gonorrhoeae, Neisseria meningitidis, Haemophilus influenzae and Salmonella species, including strains which are resistant to Cephalothin (HY-B1275A) and Gentamicin (HY-A0276A) at concentrations of less than 1 μg/mL^[1].
Moxalactam exhibits moderate activity against P. aeruginosa and is usually active against other species of Pseudomonas, Acinetobacter species are usually resistant to Moxalactam^[1].
Moxalactam has marked stability in vitro against a variety of β-lactamases, including that produced by B. fragilis, inhibits production of β-lactamases and does not induce class I β-lactamase^[1]. In Vivo: Moxalactam (Latamoxef) (0-7.4 mg/mouse; s.c.; once) is effective against bacterial infections in mice^[2].
