Paenibacillus polymyxa, also known as Bacillus polymyxa, is a Gram-positive bacterium capable of fixing nitrogen. It is found in soil, plant tissues, marine sediments and hot springs. It may have a role in forest ecosystems and potential future applications as a biofertilizer and biocontrol agent in agriculture.
Etynodiol diacetate, or ethynodiol diacetate, sold under the brand names Demulen and Femulen among others, is a progestin medication which is used in birth control pills. The medication is available only in combination with an estrogen. It is taken by mouth.
Pipamperone, also known as carpiperone and floropipamide or fluoropipamide, and as floropipamide hydrochloride (JAN), is a typical antipsychotic of the butyrophenone family used in the treatment of schizophrenia and as a sleep aid for depression. It is or has been marketed under brand names including Dipiperon, Dipiperal, Piperonil, Piperonyl, and Propitan. Pipamperone was discovered at Janssen Pharmaceutica in 1961, and entered clinical trials in the United States in 1963.
Mepitiostane, sold under the brand name Thioderon, is an orally active antiestrogen and anabolic–androgenic steroid (AAS) of the dihydrotestosterone (DHT) group which is marketed in Japan as an antineoplastic agent for the treatment of breast cancer. It is a prodrug of epitiostanol. The drug was patented and described in 1968.
Norethisterone enanthate (NETE), also known as norethindrone enanthate, is a form of hormonal birth control which is used to prevent pregnancy in women. It is used both as a form of progestogen-only injectable birth control and in combined injectable birth control formulations. It may be used following childbirth, miscarriage, or abortion. The failure rate per year in preventing pregnancy for the progestogen-only formulation is 2 per 100 women. Each dose of this form lasts two months with only up to two doses typically recommended.
Chloral betaine, also known as cloral betaine (INN), is a sedative-hypnotic drug. It was introduced by Mead Johnson in the United States in 1963. It is a betaine complex with chloral hydrate, which acts as an extended-acting formulation of chloral hydrate which is then metabolized into trichloroethanol, which is responsible for most or all of its effects.
Hydroxyprogesterone acetate (OHPA), sold under the brand name Prodox, is an orally active progestin related to hydroxyprogesterone caproate (OHPC) which has been used in clinical and veterinary medicine. It has reportedly also been used in birth control pills.
Penicillium oxalicum is an anamorph species of the genus Penicillium which was isolated from rhizosphere soil of pearl millet. Penicillium oxalicum produces secalonic acid D, chitinase, oxalic acid, oxaline and β-N-acetylglucosaminidase and occurs widespread in food and tropical commodities. This fungus could be used against soilborne diseases like downy mildew of tomatoes
Anagestone acetate, sold under the brand names Anatropin and Neo-Novum, is a progestin medication which was withdrawn from medical use.
A steroidogenesis inhibitor, also known as a steroid biosynthesis inhibitor, is a type of drug which inhibits one or more of the enzymes that are involved in the process of steroidogenesis, the biosynthesis of endogenous steroids and steroid hormones. They may inhibit the production of cholesterol and other sterols, sex steroids such as androgens, estrogens, and progestogens, corticosteroids such as glucocorticoids and mineralocorticoids, and neurosteroids. They are used in the treatment of a variety of medical conditions that depend on endogenous steroids.
Oxogestone phenpropionate, also known as xinogestone, as well as 20β-hydroxy-19-norprogesterone 20β-(3-phenylpropionate), is a progestin related to the 19-norprogesterone derivatives which was developed as an injectable hormonal contraceptive, specifically a progestogen-only injectable contraceptive, in the 1960s and early 1970s but was never marketed. It was studied at a dose of 50 to 75 mg once a month by intramuscular injection but was associated with a high failure rate with this regimen and was not further developed. OPP is the 20β-(3-phenylpropionate) ester of oxogestone, which, similarly, was never marketed.
Levonorgestrel butanoate (LNG-B), or levonorgestrel 17β-butanoate, is a steroidal progestin of the 19-nortestosterone group which was developed by the World Health Organization (WHO) in collaboration with the Contraceptive Development Branch (CDB) of the National Institute of Child Health and Human Development as a long-acting injectable contraceptive. It is the C17β butanoate ester of levonorgestrel, and acts as a prodrug of levonorgestrel in the body. The drug is at or beyond the phase III stage of clinical development, but has not been marketed at this time. It was first described in the literature, by the WHO, in 1983, and has been under investigation for potential clinical use since then.
Dicirenone is a synthetic, steroidal antimineralocorticoid of the spirolactone group which was developed as a diuretic and antihypertensive agent but was never marketed. It was synthesized and assayed in 1974. Similarly to other spirolactones like spironolactone, dicirenone also possesses antiandrogen activity, albeit with relatively reduced affinity.
Prorenoic acid, or prorenoate, is a synthetic steroidal antimineralocorticoid which was never marketed.
Methenmadinone acetate (MMA), also known as methylenedehydroacetoxyprogesterone (MDAP) and sold under the brand names Superlutin and Antigest, is a progestin medication which was developed in Czechoslovakia in the 1960s. It is the C17α acetate ester of methenmadinone.
Lynestrenol phenylpropionate (LPP), also known as ethynylestrenol phenylpropionate, is a progestin and a progestogen ester which was developed for potential use as a progestogen-only injectable contraceptive by Organon but was never marketed. It was assessed at doses of 25 to 75 mg in an oil solution once a month by intramuscular injection. LPP was associated with high contraceptive failure at the low dose and with poor cycle control. The medication was found to produce estrogenic effects in the endometrium in women due to transformation into estrogenic metabolites.
