Caspofungin-d₄  (Synonyms: MK-0991-d₄; L-743872-d₄)

Caspofungin-d₄ (MK-0991-d₄; L-743872-d₄) is a deuterium labeled Caspofungin (HY-17006A). Caspofungin is a potent antifungal agent. Caspofungin inhibits the synthesis of the fungal cell wall component β-(l,3)-D-glucan^[1][2][3].

1. This compound can be used as a tracer.
2. This compound can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.

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].

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