Lomefloxacin-d₅ hydrochloride  (Synonyms: 盐酸洛美沙星-d₅)

Lomefloxacin-d₅ (hydrochloride) is the deuterium labeled Lomefloxacin hydrochloride. Lomefloxacin (SC47111A) hydrochloride is a broad-spectrum quinolone antibiotic, with antimicrobial activity. Lomefloxacin hydrochloride is used for the research of respiratory tract infections, genitourinary infections, gastrointestinal infections, ENT infections, etc.[1][2].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
