Cefoperazone is a third-generation cephalosporin antibiotic, marketed by Pfizer under the name Cefobid. It is one of few cephalosporin antibiotics effective in treating Pseudomonas bacterial infections which are otherwise resistant to these antibiotics.
Cefoperazone is a broad-spectrum cephalosporin antibiotic used for the treatment of bacterial infections in various locations, including the respiratory tract, abdomen, skin, and female genital tracts.
Cefoperazone is a semisynthetic broad-spectrum cephalosporin proposed to be effective against Pseudomonas infections. It is a third-generation antiobiotic agent and it is used in the treatment of various bacterial infections caused by susceptible organisms in the body, including respiratory tract infections, peritonitis, skin infections, endometritis, and bacterial septicemia. While its clinical use has been discontinued in the U.S., cefoperazone is available in several European countries most commonly under the product name, Sulperazon.

Following is one of the synthesis routes:
alpha-(4-Ethyl-2,3-dioxo-1-piperazinocarbonylamino)-p-hydroxyphenylacetic acid (I) is condensed with 7-amino-3-[(1-methyl-1H-tetrazol-5-yl)thiomethyl]-3-cephem-4-carboxylic acid (II) in the presence of ethyl chlorocarbonate and N,O-bis(trimethylsilyl)acetamide in acetonitrile to produce Cefoperazone sodium.

Cefoperazone, (6R,7R)-7-[(R)-2-(4-ethyl-2,3-dioxo-1-piperazincarboxamido)-2-(p-hydroxyphenyl)acetamido]-3-[[(1-methyl-1 H-tetrazol-5-yl)thio]methyl]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-en-2-carboxylic acid (22.214.171.124), is synthesized by acylating 7-amino-3-(1-methyl-1,2,3,4-tetrazol-5-yl)-thiomethyl-3-cefem-4-carboxylic acid (126.96.36.199) with a mixed anhydride synthesized from ethyl chloroformate and α-(4-ethylpiperazin-2, 3-dion-1-carbonylamino)-4-hydroxyphenylacetic acid (188.8.131.52), which in turn is synthesized from 4-ethylpiperazin-2,3-dion-1-carboxylic acid (184.108.40.206) and the sodium salt of 4-hydroxyphenylglycine [163–168].
Cefoperazone also has a broad spectrum of antimicrobial action, including most clinically significant microorganisms: Gram-positive, Gram-negative, aerobic, and anaerobic. It is stable with respect to most beta-lactamases of Gram-positive and Gram-negative bacteria.
Cefoperazone is used for bacterial infections of the lower respiratory tract, urinary and sexual tracts, bones, joints, skin, soft tissues, abdominal, and gynecological infections. Synonyms of this drug are cefazon, cefobid, cefobis, and many others.
Spectrum of bacterial susceptibility
Cefoperazone has a broad spectrum of activity and has been used to target bacteria responsible for causing infections of the respiratory and urinary tract, skin, and the female genital tract. The following represents MIC susceptibility data for a few medically significant microorganisms.
- Haemophilus influenzae: 0.12 – 0.25 µg/ml
- Staphylococcus aureus: 0.125 – 32 µg/ml
- Streptococcus pneumoniae: ≤0.007 – 1 µg/ml
Cefoperazone contains an N-methylthiotetrazole (NMTT or 1-MTT) side chain. As the antibiotic is broken down in the body, it releases free NMTT, which can cause hypoprothrombinemia (likely due to inhibition of the enzyme vitamin K epoxide reductase) and a reaction with ethanol similar to that produced by disulfiram (Antabuse), due to inhibition of aldehyde dehydrogenase.
Mechanism of action
Cefoperazone exerts its bactericidal effect by inhibiting the bacterial cell wall synthesis, and sulbactam acts as a beta-lactamase inhibitor, to increase the antibacterial activity of cefoperazone against beta-lactamase-producing organisms.
