4-Hydroxytolbutamide-d₉  (Synonyms: Hydroxytolbutamide-d₉)

4-Hydroxytolbutamide-d₉ is the deuterium labeled 4-Hydroxytolbutamide. 4-Hydroxytolbutamide (Hydroxytolbutamide) is a metabolite of Tolbutamide. 4-Hydroxytolbutamide is metabolized by CYP2C8 and CYP2C9. Tolbutamide is a first generation potassium channel blocker and a sulfonylurea oral antidiabetic[1][2].

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].
