3α,7α-Dihydroxycoprostanic acid-d3is the deuterium labeled3α,7α-Dihydroxycoprostanic acid. 3α,7α-Dihydroxycoprostanic acid is an endogenous metabolite. 3α,7α-Dihydroxycoprostanic acid, a bile acid, is the precursor to chenodeoxycholic acid.
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].
