NCIt definition : A semisynthetic, broad-spectrum, fourth-generation cephalosporin with antibacterial
activity. Cefozopran 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.;
