羧苄青霉素 二钠盐

Carbenicillin is a semi-synthetic, broad-spectrum carboxypenicillin antibiotic with bactericidal and β-lactamase resistant activity. It is a broad-spectrum antibiotic, meaning that it is effective against a wide range of bacteria, including both Gram-positive and Gram-negative bacteria. Carbenicillin is particularly useful against Pseudomonas aeruginosa, a Gram-negative bacterium that is often resistant to other antibiotics. Carbenicillin is commonly used in cell biology applications to prevent the growth of bacterial contaminants. It is also used in microbiology to select for bacteria that have been transformed with a vector harboring the gene encoding β-lactamase, which makes them resistant to carbenicillin.

Carbenicillin disodium salt has been used: in the preparation of Luria-Bertani (LB) agar plates and mediacitationx as a selective agent in the culture media to prevent the growth of bacterial contaminantscitation in a study focused on the development of monoclonal antibodiescitation

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。

Antimicrobial spectrum: Carbenicillin acylates the penicillin-sensitive transpeptidase C-terminal domain by opening the lactam ring. This inactivation prevents the cross-linkage of peptidoglycan strands, thereby inhibiting the third and last stage of bacterial cell wall synthesis. This leads to incomplete bacterial cell wall synthesis and eventually causes cell lysis.

Mode of Action: Carboxypenicillin antibiotic that inhibits bacterial cell-wall synthesis (peptidoglycan cross-linking) by inactivating transpeptidases on the inner surface of the bacterial cell membrane.
