7α-Hydroxy-4-cholesten-3-one-d7 is the deuterium labeled 7α-Hydroxy-4-cholesten-3-one. 7α-Hydroxy-4-cholesten-3-one is an intermediate in synthesis of bile acids from cholesterol. 7α-Hydroxy-4-cholesten-3-one is a pregnane X receptor (PXR) agonist. 7α-Hydroxy-cholest-4-en-3-one is a biomarker for bile acid loss, irritable bowel syndrome, and other diseases associated with defective bile acid biosynthesis. 7α-Hydroxy-cholest-4-en-3-one is the physiological substrate for CYP8B1[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].
