一般描述
羧苄青霉素是一种半合成、广谱羧基青霉素抗生素，具有杀菌和抗β－内酰胺酶活性。它是一种广谱抗生素，即它能够有效对抗各种细菌，包括革兰氏阳性和革兰氏阴性细菌。羧苄青霉素对铜绿假单胞菌特别有效，铜绿假单胞菌是一种可以耐受其它抗生素的革兰氏阴性菌。
羧苄青霉素常用于细胞生物学应用，可防止细菌污染物的生长。在微生物学中，它也用于选择以含有编码β－内酰胺酶基因的载体转化的细菌，这使其耐受羧苄青霉素。

应用
羧苄青霉素二钠盐已用于：
- 制备LB琼脂平板和培养基
- 作为培养基中的选择剂用于防止细菌污染物的生长
- 开发单克隆抗体的研究
生化/生理作用
羧苄青霉素通过打开内酰胺环，酰化青霉素敏感性转肽酶（penicillin-sensitive transpeptidase）的C-末端结构域。这种钝化作用防止了肽聚糖束（peptidoglycan strand）的交联，从而抑制了细菌细胞壁合成的第三和最后阶段。这导致细菌细胞壁的不完全合成，最终导致细胞溶解。
作用机制：羧青霉素抗生素，可通过灭活细菌细胞膜内表面的转肽酶来抑制细菌细胞壁合成（肽聚糖交联）。
抗微生物谱：具有抗革兰氏阳性和革兰氏阴性细菌活性。
抗微生物谱：具有抗革兰氏阳性和革兰氏阴性细菌活性。
特点和优势
- 具有杀菌和抗β－内酰胺酶活性的广谱抗生素
- 有效对抗各种细菌，包括铜绿假单胞菌
- 常用于细胞生物学和生物化学应用
- 提供优于氨苄青霉素的稳定性
