What is a fluoroquinolone?
Fluoroquinolones are synthetic fluorinated analogues of nalidixic acid, a 1,8-naphthyridine and possess a 4-quinolone nucleus. [ 11] The quinolone structure consists of a bicyclic system with a substituent at position N-1, a carboxyl group at position 3, a keto group at position 4, a fluorine atom at position 6, and a substituent (often nitrogen heterocycle moiety) at the C-7. Normally, in position 2, there are no substituents, various 1-methyl-2-alkenyl-4 (1H). [ 12]
How do fluoroquinolones work?
Fluoroquinolones show their action by inhibiting the replication and transcription of bacterial DNA that is responsible for proper functioning of the cell . [ 15, 16] During DNA replication and transcription, double-stranded DNA goes to uncoil into a single-stranded structure by enzymes called DNA gyrase or DNA topoisomerase. DNA gyrase is an essential adenosine triphosphate-hydrolyzing topoisomerase II enzyme that prevents the detachment of gyrase from DNA. It consists of two A subunits (gyrA) and two B subunits (gyrB). DNA gyrase establishes negative super-helical twists in the bacterial DNA [ Figure 1 ]. [ 17] Quinolones and fluoroquinolones inhibit this enzyme by binding to the A subunit of the enzyme due to which the bacteria are unable to replicate or even synthesize proteins. There is DNA-binding groove between the A and B subunits so that binding of the fluoroquinolones to this groove may conformity change the DNA gyrase molecule. Then, DNA becomes another binding site itself, as a result fluoroquinolones bind with both DNA and DNA gyrase. In many bacteria, DNA gyrase acts as the primary site of fluoroquinolone action, including E. coli. [ 18] Fluoroquinolones have also been found to inhibit the in vitro activities of topoisomerase IV, having structure similar to DNA gyrase. [ 2] The 2 nd target site for the fluoroquinolones is topoisomerase IV, this is made up from two ParC subunits (parC) and two ParE subunits (parE). The protein subunits coded for by parC (ParC) and parE (ParE) are homologous to the A and B subunits of DNA gyrase, respectively. Topoisomerase IV carries out decatenation and relaxation of DNA and assists with the segregation of replicating chromosomes or plasmids in bacteria. [ 19] The bactericidal activity of the fluoroquinolones is enhanced by inhibition of topoisomerase IV.
How does resistance to fluoroquinolones occur?
MECHANISM OF RESISTANCE. Resistance to fluoroquinolones mostly occurs by two mechanisms that are mutations in the both target enzymes DNA gyrase in Gram-negative bacteria and topoisomerase IV in Gram-positive bacteria. The second way that reduced accumulation of the fluoroquinolones can occur is through an efflux system.
Why are quinolones restricted?
The key restriction to the use of quinolones for the treatment of community-acquired pneumonia and bronchitis had been observed because of poor in vitro activity of ciprofloxacin, ofloxacin, and norfloxacin against S. pneumoniae and anaerobic bacteria.
Why are fluoroquinolones not used clinically?
At present, these drugs not use clinically due to bacterial resistance of fluoroquinolones at molecular level by different mechanisms. The future directions of fluoroquinolones are on nucleus that may be valuable target site to increase the potency, efficacy, and decrease side effects of fluoroquinolones.
How are fluoroquinolones classified?
Fluoroquinolones are classified on the basis of their spectrum of activity [ Table 1 ]. [ 9 - 11]
What is the main mechanism of fluoroquinolones?
The main mechanism fluoroquinolones is mutations that alter the accumulation of fluoroquinolones in bacteria. The broad use of the fluoroquinolones is discussed. They are useful in the treatment of urinary tract infections, prostatitis, sexually transmitted diseases, gastrointestinal infections, osteomyelitis, and respiratory tract infections.

What are the effects of quinolones on DNA?
Quinolones and fluoroquinolones detrimentally affect the function of two enzymes produced by bacteria, topoisomerase IV and DNA gyrase, so that they can no longer repair DNA or help in its manufacture.
How do fluoroquinolones differ from quinolones?
Quinolones and fluoroquinolones also differ in the way they are absorbed, metabolized and excreted in the body.
Can you take fluoroquinolone with quinolone?
Quinolones and fluoroquinolones should be avoided in children under the age of 18 years unless they have a serious infection that cannot be treated with any other antibiotic. This is because they can damage the weight-bearing joints in children, and children are also more susceptible to other adverse effects of quinolones and fluoroquinolones, including tendinitis and tendon rupture.
