General description
Chemical structure: β-lactam
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
作用机制：青霉素G通过与青霉素结合蛋白(PBP)结合抑制肽聚糖链交联，从而抑制细胞壁合成。
抗菌谱：本品具有抗革兰氏阳性菌和革兰氏阴性菌活性。
抗菌谱：本品具有抗革兰氏阳性菌和革兰氏阴性菌活性。
