Description

Aztreonam exhibits activity in vitro against gram-negative aerobic pathogens, including P. aeruginosa. Aztreonam binds to penicillin-binding proteins of susceptible bacteria, which leads to inhibition of bacterial cell wall synthesis, followed by filamentation and cell lysis.

Cefaclor is a second-generation cephalosporin antibiotic. Cefaclor has no activity against Pseudomonas species or Acinetobacter species. Methicillin-resistant staphylococci and most strains of enterococci (eg, Str. faecalis) are resistant to cefaclor.

Cefadroxil is a cephalosporin for oral administration which inhibits bacterial wall synthesis of actively dividing cells by binding to one or more penicillin-binding proteins.

Cefalexin is an antibacterial agent of the cephalosporin class. Like other cephalosporins cefalexin exerts antibacterial activity by binding to and inhibiting the action of penicillin-binding proteins involved in the synthesis of bacterial cell walls. This leads to bacterial cell lysis and cell death.

Cefatrizine is a broad-spectrum, semisynthetic, first-generation cephalosporin with antibacterial activity. Cefatrizine binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. PBPs are enzymes involved in the terminal stages of assembling the bacterial cell wall and in reshaping the cell wall during growth and division. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This results in the weakening of the bacterial cell wall and causes cell lysis.

Cefazolin is a bactericidal cephalosporin antibiotic of the first generation for parenteral administration. Cephalosporins inhibit cell wall synthesis (in the growth stage) through blocking the penicillin-binding proteins (PBPs) like transpeptidases. The outcome is a bactericidal action.

Cefditoren is a cephalosporin with antibacterial activity against gram-positive and gram-negative pathogens. The bactericidal activity of cefditoren results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins (PBPs).

Cefepime is a broad-spectrum, bactericidal antibiotic, with activity against a wide range of Gram-positive and Gram-negative bacteria, including many strains resistant to aminoglycosides or third generation cephalosporins. It has a reduced affinity for beta-lactamases.

Cefixime is an oral third generation cephalosporin which has marked in vitro bactericidal activity against a wide variety of Gram-positive and Gram-negative organisms.

Cefotaxime exerts its action by binding to one or more of the penicillin-binding proteins (PBPs) which in turn inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls, thereby inhibiting cell wall synthesis.

Cefotetan is a bactericidal agent that acts by inhibition of bacterial cell wall synthesis. Cefotetan has activity in the presence of some beta-lactamases, both penicillinases and cephalosporinases, of gram-negative and gram-positive bacteria.

Cefoxitin is a beta-lactam antibiotic of the group of the second-generation cephalosporins.

Like other beta-lactam drugs, cefpodoxime exerts antibacterial activity by binding to and inhibiting the action of certain bacterial cell wall synthetic enzymes, namely the penicillin binding proteins.

Cefprozil is a semi synthetic broad-spectrum cephalosporin antibiotic intended for oral administration. The bactericidal action of cefprozil results from inhibition of cell-wall synthesis.

Cefradine is a broad-spectrum, bactericidal first generation cephalosporin antibiotic active against both Gram-positive and Gram-negative bacteria. It is also highly active against most strains of penicillinase producing Staphylococci. The anti-bacterial action of cefradine is through inhibition of bacterial cell wall synthesis.

In vitro studies have shown that ceftaroline is bactericidal and able to inhibit bacterial cell wall synthesis in methicillin-resistant Staphylococcus aureus (MRSA) and penicillin non-susceptible Streptococcus pneumoniae (PNSP) due to its affinity for the altered penicillin-binding proteins (PBPs) found in these organisms. As a result, minimum inhibitory concentrations (MICs) of ceftaroline against a proportion of these organisms tested fall into the susceptible range.

Ceftazidime inhibits bacterial cell wall synthesis following attachment to penicillin binding proteins (PBPs). This results in the interruption of cell wall (peptidoglycan) biosynthesis, which leads to bacterial cell lysis and death.

Ceftibuten is a semisynthetic, beta-lactamase-stable, third-generation cephalosporin with antibacterial activity. Ceftibuten binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. This results in the weakening of the bacterial cell wall and causes cell lysis.

Ceftobiprole exerts bactericidal activity through binding to important penicillin-binding proteins (PBPs) in susceptible species.

Ceftriaxone is an antibacterial for systemic use, a third-generation cephalosporin. It inhibits bacterial cell wall synthesis following attachment to penicillin binding proteins (PBPs) leading to bacterial cell lysis and death.

Cefuroxime inhibits bacterial cell wall synthesis following attachment to penicillin binding proteins (PBPs). This results in the interruption of cell wall (peptidoglycan) biosynthesis, which leads to bacterial cell lysis and death.

Doripenem is a synthetic carbapenem antibacterial agent. Doripenem exerts its bactericidal activity by inhibiting bacterial cell wall biosynthesis. Doripenem inactivates multiple essential penicillin-binding proteins (PBPs) resulting in inhibition of cell wall synthesis with subsequent cell death.

Ertapenem inhibits bacterial cell wall synthesis following attachment to penicillin binding proteins (PBPs). In Escherichia coli, affinity is strongest to PBPs 2 and 3.

Imipenem is a semi-synthetic derivative of thienamycin, the parent compound produced by the filamentous bacterium Streptomyces cattleya. Imipenem exerts its bactericidal activity by inhibiting bacterial cell wall synthesis in Gram-positive and Gram-negative bacteria through binding to penicillin-binding proteins (PBPs).

Meropenem exerts its bactericidal activity by inhibiting bacterial cell wall synthesis in Gram-positive and Gram-negative bacteria through binding to penicillin-binding proteins (PBPs).
