说明

青霉素G是一种源自肺炎链球菌的窄谱抗生素。它是A、B、C和G组链球菌、非肠道菌群D链球菌、病毒群链球菌和非青霉素酶产生葡萄球菌的首选药物。钾盐已用于研究葡萄球菌†的溶酶体和青霉素诱导的变形链球菌†的裂解。

应用

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.
 

生化/生理作用

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。
