General description

Penicillin G is a narrow spectrum antibiotic. It is effective against Streptococcus pneumoniae, groups A, B, C and G streptococci, nonenterococcal group D streptococci, viridans group streptococci, and non-penicillinase producing staphylococcus. Penicillin G contains β-lactam ring in their chemical structure.

Application

Penicillin G sodium salt has been used:
  • to study the diagnostic and therapeutic implications of gentamicin-resistant Enterococcus faecalis sequence type 6 with reduced penicillin susceptibility
  • in cell culture alone as well as in combination with streptomycin and other antibiotics
  • to inhibit the synthesis of bacterial cell walls by inhibition of the cell wall peptidoglycan chain cross-lining

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.

Packaging
