NCIt definition : A beta-lactam, first-generation cephalosporin antibiotic with bactericidal activity.
Cephradine binds to and inactivates penicillin-binding proteins (PBP) located on the
inner membrane of the bacterial cell wall. PBPs participate in the terminal stages
of assembling the bacterial cell wall, and in reshaping the cell wall during cell
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.;
