Trovafloxacin is a broad-spectrum fluoroquinolone antibiotic that inhibits the activity of DNA gyrase and topoisomerase IV, enzymes involved in DNA replication. It also acts as an effective and specific inhibitor of the pannexin 1 channel (PANX1, IC50 = 4 μM).

Fleroxacin (RO 23-6240) is a broad-spectrum antimicrobial fluoroquinolone that strongly inhibits the DNA-supercoiling activity of DNA gyrase.

DNA gyrase Topo IV-IN-1 (Compound 27) is an inhibitor of DNA gyrase and topoisomerase IV with antibacterial properties. It exhibits IC50 values of 11 and 17 nM against the DNA gyrase of Escherichia coli and methicillin-resistant Staphylococcus aureus, respectively, and IC50 values of 83 and 21 nM against topoisomerase IV of the same organisms. DNA gyrase Topo IV-IN-1 is applicable in anti-infective research.

Marbofloxacin (Zeniquin) is an effective, broad-spectrum antibiotic of bacterial, which inhibits DNA replication.

Levofloxacin is a broad-spectrum, third-generation fluoroquinolone antibiotic and optically active L-isomer of ofloxacin with antibacterial activity. Levofloxacin diffuses through the bacterial cell wall and acts by inhibiting DNA gyrase (bacterial topoisomerase II), an enzyme required for DNA replication, RNA transcription, and repair of bacterial DNA. Inhibition of DNA gyrase activity leads to blockage of bacterial cell growth.

Enoxacin (NSC-629661) is a broad-spectrum 6-fluoronaphthyridinone antibacterial agent (fluoroquinolones) structurally related to nalidixic acid.

Ciprofloxacin monohydrochloride (Bay-09867 hydrochloride) is a broad-spectrum antimicrobial carboxyfluoroquinoline.

Prulifloxacin (NM441) is a broad-spectrum fluoroquinolone antibiotic. It Inhibits bacterial DNA synthesis by inhibiting the activity of bacterial DNA topoisomerase II and IV.

Pefloxacin Mesylate (Pefloxacinium mesylate) is a synthetic broad-spectrum fluoroquinolone antibacterial agent active against most gram-negative and gram-positive bacteria.

Sparfloxacin (CI-978) is a fluoroquinolone antibiotic that inhibits bacterial DNA gyrase, thus preventing DNA replication and transcription.

Enoxacin hydrate (AT-2266 hydrate) is a broad-spectrum 6-fluoronaphthyridinone antibacterial agent.

Moxifloxacin hydrochloride (BAY12-8039 HCl) is a fourth generation fluoroquinolone with expanded activity against gram-positive bacteria as well as atypical pathogens. Moxifloxacin has been linked to mild ALT elevations during therapy and to rare instances of idiosyncratic acute liver injury with symptoms and jaundice.

Levofloxacin hydrate (Cravit hydrate) is a broad-spectrum, third-generation fluoroquinolone antibiotic and optically active L-isomer of ofloxacin with antibacterial activity. Levofloxacin diffuses through the bacterial cell wall and acts by inhibiting DNA gyrase (bacterial topoisomerase II), an enzyme required for DNA replication, RNA transcription, and repair of bacterial DNA. Inhibition of DNA gyrase activity leads to blockage of bacterial cell growth.

Antibacterial agent 169 (Compound 28), a pyrrolamide-type GyrB ParE inhibitor, exhibits antibacterial properties by inhibiting Gyrase and Topo IV in Staphylococcus aureus. It has IC 50 values of 49 nmol L and 1.513 μmol L, respectively [1].

Anti-MRSA agent 7 (Compound 12) is a potent antibacterial compound that effectively inhibits S. aureus and E. coli DNA gyrases, as well as topo IV enzymes from the same organisms, with IC50 values of 0.185 μM, 0.365 μM, 0.341 μM, and 0.059 μM, respectively [1].

Garenoxacin mesylate hydrate (Garenoxacin mesylate [USAN]) with potent antimicrobial activity, against common respiratory pathogens, including resistant strains.

Lomefloxacin (SC47111A) is a synthetic broad-spectrum fluoroquinolone with antibacterial activity.

Topoisomerase IV inhibitor 2 (compound 5d) is a potent inhibitor of DNA topoisomerase IV (TOPO IV), exhibiting IC50 values of 0.35 μM for TOPO IV and 0.55 μM for DNA gyrase. It demonstrates antibacterial properties with minimum inhibitory concentrations (MICs) of 1.985 μM against Staphylococcus aureus Newman and 0.744 μM against Escherichia coli ATCC8739 [1].

Garenoxacin (BMS284756) is a novel oral des-fluoro(6) quinolone for the treatment of Gram-positive and Gram-negative bacterial infections.
