Allgemeine Beschreibung

Chemical structure: fluoroquinolone
Norfloxacin is a broad spectrum antibiotic, which is used against a wide variety of gram positive and gram negative bacteria.

Anwendung

Norfloxacin may be used as a standard in the determination of norfloxacin in human serum samples using fluorometric spectrophotometry.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Biochem./physiol. Wirkung

Norfloxacin blockiert die DNA-Replikation durch Wechselwirkung mit einer ATP-induzierten strukturellen Transition der mit DNS-Gyrase (Topoisomerase) komplexierten DNA.
Wirkungsweise: hemmt die bakterielle DNA-Replikation
Antimikrobielles Spektrum: Gram-negative Bakterien, weniger effektiv bei Gram-positiven Bakterien

Fluoroquinolone resistance in members of the Enterobacteriaceae family is mostly due to mutations in the quinolone resistance-determining regions of the topoisomerase genes. However, transferable genes encoding quinolone resistance have recently been described. The current methods for susceptibility testing are not

Intubated patients frequently become colonized by Pseudomonas aeruginosa, which is subsequently responsible for ventilator-associated pneumonia. This pathogen readily acquires resistance against available antimicrobials. Depending on the resistance mechanism selected for, resistance might either be lost or persist after removal of

Inhibition of Nucleic Acid Synthesis by Antibiotics

Quinolones are a key group of antibiotics that interfere with DNA synthesis by inhibiting topoisomerase, most frequently topoisomerase II (DNA gyrase), an enzyme involved in DNA replication.
