Dapsone-¹⁵N₂  (Synonyms: 4,4′-Diaminodiphenyl sulfone-¹⁵N₂; DDS-¹⁵N₂)

Dapsone-¹⁵N₂ (4,4′-Diaminodiphenyl sulfone-¹⁵N₂) is ¹⁵N labeled Dapsone. Dapsone (4,4′-Diaminodiphenyl sulfone) is an orally active and blood-brain penetrant sulfonamide antibiotic with bacteriostatic, antimycobacterial and antiprotozoal activities^[1]. Dapsone?exerts effective antileprosy activity?and inhibits folate synthesis in cell extracts of?M. leprae. Dapsone is used for dermatologic disorder research, including leprosy, dermatitis herpetiformis, acne vulgaris et al^[2][3].

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.

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