ethinyl estradiol (57-63-6)  
Estinyl  ·  Ethinyloestradiol  ·  Ethynyl Estradiol
Ethinylestriol (EE3), or 17α-ethynylestriol, also known as 17α-ethynylestra-1,3,5(10)-triene-3,16α,17β-triol, is a synthetic, steroidal estrogen that was never marketed. Nilestriol, the 3-cyclopentyl ether of ethinylestriol, is a prodrug of ethinylestriol, and is a more potent estrogen in comparison, but, similarly to ethinylestriol, was never marketed. Ethinylestriol has been found to reduce the risk of 7,12-dimethylbenz(a)anthracene (DMBA)-induced mammary cancer when given as a prophylactic in animal models, while other estrogens like ethinylestradiol and diethylstilbestrol were ineffective.
estradiol (50-28-2, 73459-61-7)  
Oestradiol  ·  Estrace  ·  Vivelle
Estradiol (E2), also spelled oestradiol, is an estrogen steroid hormone and the major female sex hormone. It is involved in the regulation of the estrous and menstrual female reproductive cycles. Estradiol is responsible for the development of female secondary sexual characteristics such as the breasts, widening of the hips, and a feminine pattern of fat distribution in women and is important in the development and maintenance of female reproductive tissues such as the mammary glands, uterus, and vagina during puberty, adulthood, and pregnancy.
diethylstilbestrol (6898-97-1, 56-53-1, 22610-99-7, 64-67-5)  
Stilbestrol  ·  Distilbène  ·  Stilbene Estrogen
Medroxyprogesterone acetate (71-58-9)  
Provera  ·  DepoProvera  ·  Depo Provera
Medroxyprogesterone acetate (MPA), sold under the brand name Depo-Provera among others, is a hormonal medication of the progestin type. It is used as birth control and as part of menopausal hormone therapy. It is also used to treat endometriosis, abnormal uterine bleeding, abnormal sexuality in males, and certain types of cancer.
17alpha-Estradiol (57-91-0)  
Alfatradiol, also known as 17α-estradiol and sold under the brand names Avicis, Avixis, Ell-Cranell Alpha, and Pantostin, is a weak estrogen and a 5α-reductase inhibitor which is used as a topical medication in the treatment of androgenic alopecia (pattern hair loss) in men and women. It is a stereoisomer of the endogenous steroid hormone and estrogen 17β-estradiol (or simply estradiol).
gestonorone caproate (1253-28-7)  
Gestronol Hexanoate  ·  Depostat  ·  Schering Brand of Gestonorone Caproate
Quadrosilan (33204-77-2, 4657-20-9, 33204-76-1)  
2,6-diphenylhexamethylcyclotetrasiloxane  ·  Cisobitan  ·  2,6-diphenylhexamethylcyclotetrasiloxane, (cis)-isomer
Quadrosilan (INN, BAN) (brand name Cisobitan; former developmental code name KABI-1774) is a synthetic nonsteroidal estrogen that was developed in the 1970s and that is or has been used as an antigonadotropic agent in the treatment of prostate cancer. It is an organosilicon compound, and is also known as 2,6-cisdiphenylhexamethylcyclotetrasiloxane. Quadrosilan has estrogenic activity equivalent to that of estradiol, and can produce feminization and gynecomastia as side effects in male patients.
Bifluranol (34633-34-6)  
Bifluranol (INN, BAN; brand name Prostarex; former developmental code name BX-341) is a synthetic nonsteroidal estrogen of the stilbestrol group related to diethylstilbestrol that has been used as an antiandrogen in the United Kingdom in the treatment of benign prostatic hyperplasia. It is a polyfluorinated biphenyl that is related to polybrominated and polychlorinated biphenyls and diethylstilbestrol. The drug is described as a weak estrogen, and possesses about one-eighth the potency of diethylstilbestrol.
Dimepregnen (21208-26-4)  
Dimepregnen (INN, BAN) (developmental code name ST-1411), or 6α,16α-dimethylpregn-4-en-3β-ol-20-one, is a pregnene steroid described as an antiestrogen that was synthesized in 1968 and was never marketed. It is similar in structure to the progestins and progesterone derivatives melengestrol and anagestone.
Estromustine (62899-40-5)  
Estromustine (developmental code name Leo 271 f), also known as estrone 17β-3-N-bis(2-chloroethyl)carbamate or estrone-cytostatic complex, is a major active metabolite of the cystotatic estrogen and nitrogen mustard alkylating antineoplastic agent estramustine phosphate, a drug used in the treatment of prostate cancer.
