Uses and applications

What the substance is used for, by industry and function

Pharmacology

Phenethicillin Potassium is the potassium salt form of phenethicillin, a narrow-spectrum, beta-lactamase-sensitive penicillin with antibacterial activity. Phenethicillin binds to and inactivates the penicillin binding proteins (PBPs) located inside 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.

How it is made

Phenethicillin is prepd from 6-aminopenicillanic acid.
