General description

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.

Biochem/physiol Actions

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.

Other Notes

Keep container tightly closed in a dry and well-ventilated place.

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

Amoxicillin and clarithromycin have been proven to be effective in the treatment of community-acquired pneumonia. This study investigated the in vivo bactericidal efficacy of a novel, pulsatile dosing strategy for amoxicillin and clarithromycin, when used as monotherapy and combination therapy.

Two carbapenem-resistant isolates, one Escherichia coli isolate and one Klebsiella pneumoniae isolate, recovered from an Algerian patient expressed a novel VIM-type metallo-beta-lactamase (MBL). The identified bla(VIM-19) gene was located on a ca. 160-kb plasmid and located inside a class 1

Questions

1–3 of 3 Questions  
  1. Which method do you use to measure the potency?

    1 answer
    1. Potency is not a quality specification for the product and, for that reason, is not determined.

  2. 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
    1. 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.

  3. Solubility?

    1 answer
    1. As mentioned in the product specification sheet, this product can be solubilized in 1 M ammonium hydroxide (50 mg/ml), yielding a clear, colorless to light yellow solution.
