Nafcillin-d5 (sodium) 是 Nafcillin sodium 的氘代物。Nafcillin sodium 是一种抗生素，是可逆的 β-lactamase 抑制剂。Nafcillin sodium 可用于葡萄球菌感染的研究。 Nafcillin-d5 Sodium Salt is labeled synthetic beta-lactamase-resistant penicillin used to treat infections caused by Gram-positive bacteria, in particular, species of staphylococci that are resistant to other penicillins. Biological activity： Nafcillin-d5 (sodium) is the deuterium labeled Nafcillin sodium. Nafcillin sodium, an antibiotic, is a reversible inhibitor of β-lactamase. Nafcillin sodium can be used for the research of staphylococcal infections In vitro research： 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
