Descrizione generale

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

Applicazioni

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.

Azioni biochim/fisiol

Norfloxacin blocks DNA replication by interfering with an ATP-induced structural transition of DNA complexed with DNA gyrase (topoisomerase).
Mode of action: inhibits bacterial DNA replication
Antimicrobial spectrum: Gram-negative bacteria; less effective against Gram-positive bacteria

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

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.
