Descrizione generale

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.

Applicazioni

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

Azioni biochim/fisiol

Modalità d′azione: La penicillina G agisce inibendo la sintesi della parete cellulare attraverso il legame con le proteine leganti la penicillina (PBP) e inibendo il legame crociato con le catene dei peptidoglicani.

Spettro antimicrobico: Il prodotto è attivo nei confronti di batteri gram positivi e gram negativi.
