Uses and applications

What the substance is used for, by industry and function

Pharmacology

Propicillin Potassium is the potassium salt form of propicillin, a semisynthetic acid-stable penicillin with antibacterial activity. Propicillin binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This interrupts bacterial cell wall synthesis and results in the weakening of the bacterial cell wall, eventually causing cell lysis.
