Ceftiofur-d₃ sodium  (Synonyms: 头孢噻呋钠-d₃)

Ceftiofur-d₃ sodium is deuterium labeled Ceftiofur sodium (HY-B0898). Ceftiofur sodium is a cell wall synthesis inhibitor that targets bacterial penicillin-binding proteins (PBPs) and has anti-inflammatory effects in endotoxemia. Ceftiofur sodium exerts bactericidal effects by inhibiting the synthesis of bacterial cell wall peptidoglycan, leading to bacterial cell lysis. Ceftiofur sodium also inhibits the activation of NF-κB and MAPKs, thereby reducing the secretion of pro-inflammatory cytokines such as TNF-α, IL-1β, and IL-6^[1][2][3][4].

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^[1].

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