Chemical Structure
Finafloxacin hydrochloride
- CAS No.: 209342-41-6
- Formula:C20H20ClFN4O4
- Molecular Weight:434.85
IUPAC Name: 8-cyano-1-cyclopropyl-6-fluoro-7-((4aS,7aS)-hexahydropyrrolo[3,4-b][1,4]oxazin-6(2H)-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylic acid hydrochloride
InChIKey: CQMSQUOHWYYEKM-MOGJOVFKSA-N
SMILES: O=C(C1=CN(C2CC2)C3=C(C=C(F)C(N4C[C@]5([H])OCCN[C@@]5([H])C4)=C3C#N)C1=O)O.Cl
Biological Activity: Finafloxacin hydrochloride is an orally active fluoroquinolone antibacterial agent. Finafloxacin hydrochloride exerts broad-spectrum antibacterial activity by promoting DNA cleavage in the gyrase/topoisomerase IV (Topoisomerase IV) complex and inhibiting DNA synthesis. Finafloxacin hydrochloride is a weak substrate of NorA/Lde, can be effluxed by BpeAB-OprB/BpeEF-OprC, and can overcome BpeEF-OprC-mediated fluoroquinolone resistance, while also accumulating in macrophages and exhibiting intracellular bactericidal activity. Finafloxacin hydrochloride can be used for research on intracellular bacterial infections, melioidosis, tularemia, plague, acute otitis externa, complicated urinary tract infections, and pyelonephritis[1][2][3][4][5].
