Mestranol-d₄  (Synonyms: 美雌醇-d₄)

Mestranol-d4 is the deuterium labeled Mestranol. Mestranol is an inactive proagent and becomes biologically active on conversion to ethinyl estradiol (EE). Mestranol acts as an estrogen receptor agonist. Mestranol combines with a progestin in vivo and can be used for the research of menopausal hormone or menstrual disorders[1][2][3]. Mestranol-d4 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
