Description générale
Chemical structure: ß-lactam
Application
Amoxicillin is used to study the oxygen dependent antimicrobial systems of polymorphonuclear leukocytes (PMNLs), the risk of resistance development in Helicobacter pylori, and various dosing strategies against Streptococcus pneumoniae and Pneumococcal pneumonia [1][2][3][4]. It is also used to study the synthesis of bacterial cell walls at the level of peptidoglycan polymer chain cross-linking involving bacterial transpeptidase.
Actions biochimiques/physiologiques
Amoxicillin is a broad-spectrum, β-lactam antibiotic. It is a 4-hydroxy analog of ampicillin with similar ranges of actions and utility to ampicillin. Amoxicillin inhibits the cross-linkage between linear peptidoglycan polymer chains that are the major component of both Gram-positive and Gram-negative bacteria.
Autres remarques

The characterization of AmpC-type beta-lactamases was performed in a collection of 32 clinical Pseudomonas aeruginosa isolates with intermediate susceptibility or resistance to imipenem and ceftazidime. Twenty-one out of those 32 isolates overexpressed AmpC beta-lactamase, and the MICs of ceftazidime and

Beta-Lactam antimicrobials are dosed intermittently or continuously based on their short half-lives and concentration-independent activity. Based on the relationship between antimicrobial killing and bacterial growth cycle, the pharmacodynamics of a unique pulsatile strategy was investigated. In vitro pharmacodynamic models with

A multidrug-resistant Escherichia coli isolate recovered in Australia produced a carbapenem-hydrolyzing β-lactamase. Molecular investigations revealed the first identification of the bla(NDM-1) metallo-β-lactamase gene in that country. In addition, this E. coli isolate expressed the extended-spectrum β-lactamase CTX-M-15, together with two

Bonjour, je n'ai pas trouvé de fiche pour savoir comment solubiliser à 10 mg/ml de l'amoxicilline A8523 ? Je veux traiter des souris par voie intraperitoneale, et je ne peux pas injecter plus de 100µl. Merci . Catherine
1 answer-
This product is soluble at 50 mg/mL in 1M Ammonium Hydroxide. This stock may then be diluted in a physiologic buffer. This product is not tested for in vivo or in vitro use. Stock solutions would require filter sterilization before use. Also, note that this product tends to have a high moisture content.
It is advised to review the lot-specific Certificate of Analysis to accurately prepare a stock solution.Helpful?
