Application

Penicillin G is a narrow spectrum antibiotic derived from Streptococcus pneumoniae. It is the drug of choice for groups A, B, C and G streptococci, nonenterococcal group D streptococci, viridians group streptococci, and non-penicillinase producing staphylococcus. The potassium salt has been used to study murosomes of staphylococci and the penicillin-induced lysis of Streptococcus mutans.

Biochem/physiol Actions

Mode of Action: Penicillin G acts by inhibiting cell wall synthesis through binding to penicillin binding proteins (PBPs), inhibiting peptidoglycan chain cross-linking.

Antimicrobial spectrum: This product is active against gram-positive and gram-negative bacteria.
