Tetrahydrouridine-d3_product_DataBase

Bioactivity	Tetrahydrouridine-d3 is the deuterium labeled Tetrahydrouridine[1]. Tetrahydrouridine dihydrate is potent inhibitor of cytidine deaminase (CDA), which competitively blocks the enzyme's active site more effectively than intrinsic cytidine[2][3].
Invitro	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].
