Description:
Estradiol benzoate (INN; brand names Agofollin, Diffolisterol, Progynon-B, many others), or oestradiol benzoate (BAN), is a synthetic ester, specifically the 3-benzoyl ester, of the naturalestrogen, estradiol. It was the first form of estrogen to be marketed, patented by Schering-Kahlbaun in 1936 in an oil preparation for injectable use and introduced later that year asProgynon-B.Though it is still in widespread use today, it has been mostly superseded by newer forms of estradiol with improved pharmacokinetics in which require less frequent administration such as estradiol cypionate and estradiol valerate.
Estradiol, or more precisely, 17β-estradiol, is a human sex hormone and steroid, and the primary female sex hormone. It is named for and is important in the regulation of the estrous and menstrual female reproductive cycles. Estradiol is essential for the development and maintenance of female reproductive tissues but it also has important effects in many other tissues including bone. While estrogen levels in men are lower compared to women, estrogens have essential functions in men as well. Estradiol is found in most vertebrates as well as many crustaceans, insects, fish, and other animal species.
Estradiol or oestradiol (American or British English usages), derives from estra-, Gk. οστρο (oistros, literally meaning "verve or inspiration") and -diol, a chemical name and suffix indicating that this form of steroid and sex hormone is a type of alcohol bearing two hydroxyl groups.
Estradiol is produced especially within the follicles of female ovaries, but also in other endocrine (i.e., hormone-producing) and non-endocrine tissues (e.g., including fat, liver, adrenal, breast, and neural tissues). Estradiol is biosynthesized from progesterone (arrived at in two steps from cholesterol, via intermediate pregnenolone).One principle pathway then converts progesterone to its 17-hydroxy-derivative, and then to androstenedione via sequential cytochrome P450-catalyzed oxidations. Action of aromatase on this dione generates estrone, and action of a dehydrogenase on this gives the title compound, 17β-estradiol.
