16α-Hydroxyprednisolone-d3_product_DataBase

Bioactivity	16α-Hydroxyprednisolone-d3 is the deuterium labeled 16α-Hydroxyprednisolone. 16α-Hydroxyprednisolone is a stereoselective metabolite of the 22(R) epimer of the glucocorticoid budesonide via cytochrome P450 3A (CYP3A) enzymes[1][2].
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].
