Cefaclor is a second generation cephalosporin antibiotic isolated from the Acremonium fungus. It targets a wide variety of bacteria including Streptococcus pneumoniae and Haemophilus influenzae and a variety of other gram-negative and gram-positive bacteria. In addition, cefaclor has been useful in studying urinary tract and intra-abdominal infections and the mechanisms of renal transporters hOTA1, hPEPT1, and hPEPT2.

Cefadroxil is a first generation cephalosporin antibiotic with a structure similar to that of cephalexin and cephradine. It targets a wide variety of bacterial species including Staphylococcus and Streptococcus species.

Cefamandole nafate is a second generation cephalosporin antibiotic. It is effective against a variety of gram-negative and gram-positive bacteria. It has been used to study the expression and inhibition of the penicillin binding proteins, especially PBP 2A. Cefamandole nafate is freely soluble in aqueous solution and methanol.

Cefamandole sodium salt is a second generation cephalosporin antibiotic. It is effective against a variety of gram-negative and gram-positive bacteria. It has been used to study the expression and inhibition of the penicillin binding proteins, especially PBP 2A. Cefamandole sodium salt is freely soluble in aqueous solution.

Cefdinir is a third generation cephalosporin antibiotic with resistance to many β-lactamase enzymes. It is effective against gram-positive and gram-negative bacteria. Cefdinir has been used to study infections caused by Staphylococcus aureus and Neisseria gonorrhoeae as well as ftsl gene transfer in H. influenzae. It is an inhibitor of neutrophil myeloperoxidases and exhibits structural similarity to cefixime.

Cefditoren pivoxil is a β-lactam, cephalosporin antibiotic that has shown to be effective against an array of gram positive and negative bacteria. In vitro studies have exhibited cefditoren pixovil to have strong activity towards methicillin and penicillin-susceptible pathogens as well as penicillin-resistant Streptococcus pneumoniae.

Cephalosporins are a type of β-lactam antibiotic consisting of a four-membered β-lactam ring bound to a six-membered dihydrothiazine ring. This two-ring system causes distortion of the β-lactam amide bond, resulting in decreased resonance stabilization and increased reactivity. β-lactams inhibit the formation of peptidoglycan cross-links within bacterial cell walls by targeting penicillin-binding proteins or PBPs. Consequently, the bacterial cell wall becomes weak and cytolysis occurs. Cephalosporin compounds are less susceptible to β-lactamases than the penicillin β-lactam antibiotics.

Antibiotics are often used in clinical in vitro tests known as antimicrobial susceptibility tests or ASTs to determine their efficacy against certain bacterial species. They are tested against gram-negative and gram-positive bacteria using panels, discs, and MIC strips by medical microbiologists. ASTs decrease the risk of using an antibiotic against bacteria exhibiting resistance to it, and the results are used in clinical settings to determine which antibiotic(s) to prescribe for various infections.

Cefditoren sodium is sodium salt of a β-lactam cephalosporin antibiotic that disrupts peptidoglycan synthesis of bacterial cell walls. Cefditoren sodium has been used in comparative studies to ascertain effectiveness of newly synthesized antibiotics as well as in vitro testing of antibiotic resistance in bacteria.

Cefepime is a fourth generation cephalosporin antibiotic effective against gram-negative and gram-positive bacteria. It is resistant to a variety of β-lactamases, and is effective against some naturally resistant bacterial species such as Pseudomonas aeruginosa, Staphylococcus aureus, and Streptococcus pneumoniae. Cefepime is slightly soluble in aqueous solution.

Cefepime is a fourth generation cephalosporin antibiotic effective against gram-negative and gram-positive bacteria. It is resistant to a variety of β-lactamases, and is effective against some naturally resistant bacterial species such as Pseudomonas aeruginosa, Staphylococcus aureus, and Streptococcus pneumoniae. Cefepime HCl is more soluble compared to the pure Cefepime. Both forms have similar potencies and both are suitable for microbiology use. However, Cefepime HCl can be easier to work with because of its higher aqueous solubility.

Cefixime trihydrate is a broad-spectrum third generation cephalosporin targeting a wide range of gram-positive and gram-negative organisms. It is also used to detect ytterbium in mineral probes.

Cefmetazole free acid is a second generation cephalosporin antibiotic that has a broad range of activity against gram-negative and gram-positive bacterium. Cefmetazole has exhibited great bactericidal activity against Staphylococcus aureus, which includes some methicillin-resistant strains.
