CAS 100986-89-8: Levofloxacin Q-acid

Description: Levofloxacin Q-acid, with the CAS number 100986-89-8, is a chemical compound that is a derivative of levofloxacin, which is a fluoroquinolone antibiotic. This substance is characterized by its ability to inhibit bacterial DNA gyrase and topoisomerase IV, enzymes critical for bacterial DNA replication and transcription. Levofloxacin Q-acid is typically a white to off-white crystalline powder, soluble in water and various organic solvents, which facilitates its use in pharmaceutical formulations. Its molecular structure includes a bicyclic core with a fluorine atom, contributing to its broad-spectrum antibacterial activity against both Gram-positive and Gram-negative bacteria. The compound is often utilized in the treatment of respiratory tract infections, urinary tract infections, and skin infections. Additionally, it may exhibit some degree of phototoxicity and has specific storage requirements to maintain its stability. As with other fluoroquinolones, it is essential to monitor for potential side effects, including tendonitis and effects on the central nervous system.
