Description

General description

Chemical structure: quinolone

Application

Oxolinic acid is used to study new transmissible resistance mechanisms qnrA, qnrB, qnrS, and aac(6′)Ib-cr, in Escherichia coli and Salmonella enterica. Oxolinic acid is added to culture medium for the isolation of Gardnerella vaginalis[1].

Biochem/physiol Actions

Oxolinic acid is a quinolone antibiotic. It is a DNA-gyrase (topoisomerase II) inhibitor used for studies on DNA winding and coiling and acts as a dopamine reuptake inhibitor for studies on dopaminergic neurotransmission processes.
