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.

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.

The antimicrobial agent oxolinic acid, injected i.p. in mice, induced a dose dependent increase in locomotor activity. This stimulation culminated at the 32 mg/kg dose and became smaller for higher doses (64-128 mg/kg). When opposed to increasing doses (50-100-200 microg/kg

This study presents the development of an automated on-line solid phase extraction (SPE)-liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the determination of 23 antibiotics in environmental water samples. After optimisation of LC-MS/MS conditions, SPE parameters such as sorbent type, sample
