1-Cyclopropyl-6-fluoro-4-oxo-7-[(1S,4S)-5-(trideuteriomethyl)-2,5-diazabicyclo[2.2.1]heptan-2-yl]quinoline-3-carboxylic acid

1-Cyclopropyl-6-fluoro-4-oxo-7-[(1S,4S)-5-(trideuteriomethyl)-2,5-diazabicyclo[2.2.1]heptan-2-yl]quinoline-3-carboxylic acid, also known as levofloxacin-d3 carboxylic acid, is an antibiotic that belongs to the fluoroquinolone class. It is used to treat a variety of bacterial infections, such as respiratory tract infections, urinary tract infections, and skin infections. The chemical formula for levofloxacin-d3 carboxylic acid is C22H18D3FN4O3, and it has a molecular weight of 426.48 g/mol. The compound is a yellow crystalline powder that is soluble in water and slightly soluble in ethanol. Levofloxacin-d3 carboxylic acid works by inhibiting the activity of bacterial DNA gyrase and topoisomerase IV, which are enzymes responsible for DNA replication and repair. This leads to the disruption of bacterial DNA synthesis and ultimately results in bacterial death. Like other fluoroquinolones, levofloxacin-d3 carboxylic acid has been associated with several adverse effects, including gastrointestinal disturbances, central nervous system effects, and tendon rupture. It is important to use this medication under the guidance of a healthcare provider and to follow dosing instructions carefully to minimize the risk of adverse effects.
