HY-B0390

Mestranol		Alkynes
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. Mestranol is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

HY-B0390S

Mestranol-d2		Alkynes
Mestranol-d2 is the deuterium labeled Mestranol. Mestranol is an inactive proagent and becomes biologically active on conversion to ethinyl estradiol (EE).
