General Description
Ticarcillin disodium salt is the disodium salt form of ticarcillin, a broad-spectrum, semi-synthetic penicillin antibiotic with bactericidal and beta-lactamase resistant activity. Similar to carbenicillin in action, ticarcillin inactivates 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.
Chemical structure: ß-lactam
Application:
Ticarcillin is a semisynthetic antibiotic with a broad spectrum of bactericidal activity against many gram-positive and gram-negative aerobic and anaerobic bacteria. It is commonly used in combination with clavulanate in order to improve it′s efficacy. It is used to study appropriate dosing in pediatric patients who have cystic fibrosis.
Biochem/physiol Actions
Ticarcillin is a β-Lactam antibiotic that prevents bacterial cell wall biosynthesis at the level of peptidogylcan cross-linking by inhibiting peptidoglycan transpeptidases. It is derived from penicillin and is similar to carbenicillin in action. Ticarcillin is susceptible to degradation by ß-lactamases.
