| Bioactivity | Estetrol-d4 is the deuterium labeled Estetrol. Estetrol, a natural estrogen synthesized exclusively during pregnancy by the human fetal liver, is a selective nuclear estrogen receptor modulator. Estetrol exerts estrogenic actions on the endometrium or the central nervous system but presents antagonistic effects on the breast[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]. |
