General description
β-Estradiol 17-valerate is a synthetic estrogen.
Application
β-Estradiol 17-valerate has been used:
- in an in-vivo assay, to synchronize the estrus cycle in athymic nude mice, to study the effect of recombinant pigment epithelium-derived factor (rPEDF) on induced ectopic fibroid lesions
- to study the influence of ovarian hormones on type II cGMP-dependent protein kinase (Prkg2) expression in mice
- to induce growth of estrogen-dependent tumor cells in athymic nude mice to establish a breast cancer mouse model
Biochem/physiol Actions
Estradiol valerate is observed to be useful for treating menopausal climacteric symptoms. β-Estradiol 17-valerate is used as a source of 17β-estradiol (E2) in in vitro fertilization, hormone replacement therapy, contraceptive drugs, to study reproductive disorders in animal models. It serves as growth promoter in animal farming. β-Estradiol 17-valerate is also used to culture single-sex population among fish. Studies in rats show that β-Estradiol 17-valerate has negative effects on the estrus cycle pattern.
