Estrone sulfate-d₅ sodium 

Estrone sulfate-d₅ sodium is the deuterium labeled Estrone sulfate sodium (HY-113293B). Estrone sulfate sodium is an inactive endogenous estrogen that can be converted into Estrone (HY-B0234) and Estradiol (HY-B0141). Estrone sulfate sodium is also a substrate of the OATP1B3 transporter. Estrone sulfate sodium can be converted into Estrone and Estradiol in normal mammary parenchymal cells. Estrone sulfate sodium stimulates the growth of nitrosomethylurea-induced mammary tumors in ovariectomized rats and the colony formation of dispersed nitrosomethylurea mammary cells, with conversion into Estrone and Estradiol occurring both in vivo and in vitro during this process. Estrone sulfate sodium is applicable to breast cancer-related research^[1][2][3][4].

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].
