描述

General description

Chemical structure: β-lactam

Application

Cefradin was used to study the effect of expression, binding, and inhibition of PBP3 and other penicillin-binding proteins (PBPs) on bacterial cell wall mucopeptide synthesis.

Biochem/physiol Actions

Cefradin is a semi-synthetic cephalosporin that inhibits the last stage of bacterial cell wall synthesis by binding to certain penicillin-binding proteins (PBPs), such as PBP3, which results in cell lysis. Cell lysis is mediated by bacterial cell wall autolytic enzymes. It is effective against Gram-positive and Gram-negative bacteria. Cefradin may also interfere with autolysin inhibitors.

Other Notes

Keep container tightly closed in a dry and well-ventilated place.
