11-Dehydroprogesterone, also known as pregna-4,11-diene-3,20-dione, is a steroidal progestin that was never marketed. [1] [2] [3] It was found to be 2- to 3-fold as potent as progesterone as a progestogen in animal bioassays, [1] [4] although other studies found them to be equivalent in potency. [2] 11-Dehydroprogesterone has been studied in women. [5] It was discovered in the 1930s or 1940s, and was one of the earliest synthetic progestogens. [3]

<span class="mw-page-title-main">Progestogen</span> Steroid hormone that activates the progesterone receptor

Progestogens, also sometimes written progestagens or gestagens, are a class of natural or synthetic steroid hormones that bind to and activate the progesterone receptors (PR). Progesterone is the major and most important progestogen in the body. The progestogens are named for their function in maintaining pregnancy, although they are also present at other phases of the estrous and menstrual cycles.

<span class="mw-page-title-main">19-Norprogesterone</span> Chemical compound

19-Norprogesterone, also known as 19-norpregn-4-ene-3,20-dione, is a steroidal progestin and close analogue of the sex hormone progesterone, lacking only the C19 methyl group of that molecule. It was first synthesized in 1944 in the form of a mixture that also included unnatural stereoisomers of progesterone, and this mixture was found to be at least equivalent to progesterone in terms of progestogenic activity. Subsequent investigations revealed that 17-isoprogesterone and 14-iso-17-isoprogesterone are devoid of progestogenic activity. 19-Norprogesterone was resynthesized in 1951 with an improved method, and was confirmed to be the component of the mixture synthesized in 1944 that was responsible for its progestogenic activity. In 1953, a paper was published showing that 19-norprogesterone possessed 4- to 8-fold the activity of progesterone in the Clauberg assay in rabbits, and at the time of this discovery, 19-norprogesterone was the most potent progestogen known.

<span class="mw-page-title-main">3β-Dihydroprogesterone</span> Chemical compound

3β-Dihydroprogesterone (3β-DHP), also known as 3β-hydroxyprogesterone, or pregn-4-en-3β-ol-20-one, is an endogenous steroid. It is biosynthesized by 3β-hydroxysteroid dehydrogenase from progesterone. Unlike 3α-dihydroprogesterone (3α-DHP), 3β-DHP does not act as a positive allosteric modulator of the GABAA receptor, which is in accordance with the fact that other 3β-hydroxylated progesterone metabolites such as isopregnanolone and epipregnanolone similarly do not act as potentiators of this receptor and instead inhibit it as well as reverse the effects of potentiators like allopregnanolone. 3β-DHP has been reported to possess about the same potency as progesterone in a bioassay of progestogenic activity, whereas 3α-DHP was not assessed.

<span class="mw-page-title-main">Progestogen ester</span> Drug class

A progestogen ester is an ester of a progestogen or progestin. The prototypical progestogen is progesterone, an endogenous sex hormone. Esterification is frequently employed to improve the pharmacokinetics of steroids, including oral bioavailability, lipophilicity, and elimination half-life. In addition, with intramuscular injection, steroid esters are often absorbed more slowly into the body, allowing for less frequent administration. Many steroid esters function as prodrugs.

<span class="mw-page-title-main">Quingestrone</span> Progestin medication

Quingestrone, also known as progesterone 3-cyclopentyl enol ether (PCPE) and sold under the brand name Enol-Luteovis, is a progestin medication which was previously used in birth control pills in Italy but is now no longer marketed. It is taken by mouth.

<span class="mw-page-title-main">17α-Methylprogesterone</span> Chemical compound

17α-Methylprogesterone (17α-MP), or 17α-methylpregn-4-ene-3,20-dione, is a steroidal progestin related to progesterone that was synthesized and characterized in 1949 but was never marketed. Along with ethisterone (1938) and 19-norprogesterone (1951), 17α-MP was one of the earliest derivatives of progesterone to be identified as possessing progestogenic activity. Similarly to progesterone and derivatives like 17α-hydroxyprogesterone and 19-norprogesterone, 17α-MP was found to possess poor oral bioavailability, but showed improved progestogenic activity relative to progesterone when administered via other routes. In addition to its activity as a progestogen, 17α-MP has also been found to possess some antiglucocorticoid activity.

<span class="mw-page-title-main">Progesterone 3-acetyl enol ether</span> Chemical compound

Progesterone 3-acetyl enol ether, also known as progesterone acetate, as well as 3-acetoxypregna-3,5-dien-20-one, is a progestin which was never marketed. It was reported to possess similar potency to progesterone and hydroxyprogesterone caproate in the rabbit endometrial carbonic anhydrase test, a bioassay of progestogenic activity. In addition, it was able to maintain pregnancy in animals. Progesterone 3-acetyl enol ether is closely related to quingestrone, which is also known as progesterone 3-cyclopentyl enol ether and was formerly marketed as an oral contraceptive.

<span class="mw-page-title-main">18-Methylsegesterone acetate</span> Chemical compound

18-Methylsegesterone acetate is a progestin medication of the 19-norprogesterone group which was never marketed. It was first described in a patent in 1997 and then in a literature paper in 2003. 18-Methyl-SGA is the C18 methyl or C13β ethyl derivative of segesterone acetate, and shows 3 to 10 times the progestogenic potency of SGA in bioassays. This is analogous to the case of the 19-nortestosterone progestin norethisterone and its 18-methyl derivative levonorgestrel, the latter showing substantially increased potency relative to the former similarly. As SGA is already one of the most potent progestins to have been developed, with 100-fold the potency of progesterone and 10-fold the potency of levonorgestrel in bioassays, 18-methyl-SGA is an extremely potent progestogen, among if not the most potent known.

<span class="mw-page-title-main">Ethinylandrostenediol</span> Chemical compound

Ethinylandrostenediol, also known as 17α-ethynyl-5-androstenediol, is a synthetic estrogen, progestogen, and androgen which was never marketed. It is the C17α ethynyl derivative of the androgen precursor and prohormone 5-androstenediol.
