Usage: Estradiol is the major estrogen secreted by the premenopausal ovary. Estradiol benzoate is an estradiol analog which contains a benzyl ester at the C-3 position. Estradiol benzoate is useful in the tr eatment of lesions produced by diminution of bodily production of estrogens.
Estrogens direct the development of the female genotype in embryogenesis and at puberty. Estradiol is the major estrogen secreted by the premenopausal ovary. Estradiol benzoate is an estradiol analog which contains a benzyl ester at the C-3 position and is often used in combination with a progestin to induce estrus in domestic livestock. This compound binds to the human and murine estrogen receptor α (ERα), and chicken ER with IC50 values in the range of 22-28 nM. This reflects a 6-10 fold reduction in binding affinity compared to estradiol.
2.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use and introduced later that year asProgynon-B.Though it is still in widespread use today, it has been mostly superseded by newer forms of estradiol with improved pharmacokinetics in which require less frequent administration such as estradiol cypionate and estradiol valerate.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.
3.Application :
Female reproduction:In the female, estradiol acts as a hormone for tissue of the reproductive organs, supporting the lining of the vagina, the cervical glands, the endometrium, and the lining of the fallopian tubes. It enhances growth of the myometrium. Estradiol appears necessary to maintain oocytes in the ovary. During the menstrual cycle, estradiol produced by the growing follicle triggers, via a positive feedback system, the hypothalamic-pituitary events that lead to the luteinizing hormone surge, inducing ovulation. In the luteal phase, estradiol, in conjunction with progesterone, prepares the endometrium for implantation. During pregnancy, estradiol increases due to placental production. In baboons, blocking of estrogen production leads to pregnancy loss, suggesting estradiol has a role in the maintenance of pregnancy. Research is investigating the role of estrogens in the process of initiation of labor. Actions of estradiol are required before the exposure of progesterone in the luteal phase.
Sexual development:The development of secondary sex characteristics in women is driven by estrogens, to be specific, estradiol. These changes are initiated at the time of puberty, most are enhanced during the reproductive years, and become less pronounced with declining estradiol support after the menopause. Thus, estradiol enhances breast development, and is responsible for changes in the body shape, affecting bones, joints and fat deposition. Fat structure and skin composition are modified by estradiol.
Male reproduction:The effect of estradiol (and estrogens) upon male reproduction is complex. Estradiol is produced by action of aromatase mainly in the Leydig cells of the mammalian testis, but also by some germ cells and the Sertoli cells of immature mammals. It functions (in vitro) to prevent apoptosis of male sperm cells.
Several studies have noted sperm counts have been declining in many parts of the world, and estrogen exposure in the environment has been postulated to be the cause.Suppression of estradiol production in a subpopulation of subfertile men may improve the semen analysis.Males with sex chromosome genetic conditions, such as Klinefelters syndrome, will have a higher level of estradiol.
Bone:Estradiol has a profound effect on bone. Individuals without it (or other estrogens) will become tall and eunuchoid, as epiphyseal closure is delayed or may not take place. Bone structure is affected also, resulting in early osteopenia and osteoporosis. Also, women past menopause experience an accelerated loss of bone mass due to a relative estrogen deficiency.
Liver:Estradiol has complex effects on the liver. It can lead to cholestasis. It affects the production of multiple proteins, including lipoproteins, binding proteins, and proteins responsible for blood clotting.
