Description


Norfloxacin is only found in individuals that have used or taken this drug. It is a synthetic fluoroquinolone (fluoroquinolones) with broad-spectrum antibacterial activity against most gram-negative and gram-positive bacteria. Norfloxacin inhibits bacterial DNA gyrase. [PubChem]The bactericidal action of Norfloxacin results from inhibition of the enzymes topoisomerase II (DNA gyrase) and topoisomerase IV, which are required for bacterial DNA replication, transcription, repair, and recombination. Norfloxacin is a broad-spectrum antibiotic that is active against both gram-positive and gram-negative bacterias. The fluorine atom at the 6 position increases potency against gram-negative organisms, and the piperazine moiety at the 7 position is responsible for anti-pseudomonal activity J - Antiinfectives for systemic use > J01 - Antibacterials for systemic use > J01M - Quinolone antibacterials > J01MA - Fluoroquinolones D004791 - Enzyme Inhibitors > D065607 - Cytochrome P-450 Enzyme Inhibitors > D065609 - Cytochrome P-450 CYP1A2 Inhibitors D000970 - Antineoplastic Agents > D059003 - Topoisomerase Inhibitors > D059005 - Topoisomerase II Inhibitors S - Sensory organs > S01 - Ophthalmologicals > S01A - Antiinfectives > S01AE - Fluoroquinolones D000890 - Anti-Infective Agents > D000900 - Anti-Bacterial Agents > D024841 - Fluoroquinolones C254 - Anti-Infective Agent > C258 - Antibiotic > C795 - Quinolone Antibiotic CONFIDENCE standard compound; EAWAG_UCHEM_ID 232 CONFIDENCE standard compound; INTERNAL_ID 1032
