'''Lynestrenol''' is a [[progestagen]] hormone. It is a synthetic orally-available progestagen associated with numerous effects of the natural progesterone hormone. Lynestrenol has a strong progestational effect on the uterine endometrium (transforming proliferative endometrium into secretory one), inhibits secretion of gonadotropin, suppresses maturation of follicles in the ovaries and ovulation, reduces menstrual bleeding. |
|||
'''Lynestrenol''', sold under the brand names '''Exluton''' and '''Ministat''' among others, is a [[progestin]] medication which is used in [[birth control pills]] and in the treatment of [[gynecological disorder]]s.<ref name="Elks2014">{{cite book | vauthors = Elks J |title=The Dictionary of Drugs: Chemical Data: Chemical Data, Structures and Bibliographies|url=https://books.google.com/books?id=0vXTBwAAQBAJ&pg=PA747|date=14 November 2014|publisher=Springer|isbn=978-1-4757-2085-3|pages=747–}}</ref><ref name="IndexNominum2000">{{cite book|title=Index Nominum 2000: International Drug Directory|url=https://books.google.com/books?id=5GpcTQD_L2oC&pg=PA624|year=2000|publisher=Taylor & Francis|isbn=978-3-88763-075-1|pages=624–}}</ref><ref name="MortonHall2012">{{cite book | vauthors = Morton IK, Hall JM |title=Concise Dictionary of Pharmacological Agents: Properties and Synonyms|url=https://books.google.com/books?id=tsjrCAAAQBAJ&pg=PA170|date=6 December 2012|publisher=Springer Science & Business Media|isbn=978-94-011-4439-1|pages=170–}}</ref> The medication is available both alone and in combination with an [[estrogen (medication)|estrogen]].<ref name="IndexNominum2000" /><ref name="Muller1998" /><ref name="Drugs.com">{{Cite web|url= https://www.drugs.com/international/lynestrenol.html |title = Lynestreno |work = Drugs.com l}}</ref> It is taken [[oral administration|by mouth]].<ref name="pmid436304" /><ref name="pmid18356043" /> |
|||
This synthetic gestagen is associated with minimal estrogenic, androgenic and anabolic effects. |
|||
Lynestrenol is used in treatment of hormonal disorders and diseases caused by insufficient secretion of the natural progesterone, except in case of risky pregnancies and prevention of miscarriage, since it is not efficient enough in this indication. |
|||
<!-- Side effects and mechanism --> |
|||
== Pharmacology == |
|||
Lynestrenol is a progestin, or a [[synthetic compound|synthetic]] [[progestogen (medication)|progestogen]], and hence is an [[agonist]] of the [[progesterone receptor]], the [[biological target]] of progestogens like [[progesterone]].<ref name="pmid19434889" /> It has weak [[androgen]]ic and [[estrogen (medication)|estrogen]]ic activity and no other important [[hormonal agent|hormonal]] activity.<ref name="pmid19434889" /><ref name="pmid16112947">{{cite journal | vauthors = Kuhl H | title = Pharmacology of estrogens and progestogens: influence of different routes of administration | journal = Climacteric | volume = 8 | pages = 3–63 | date = August 2005 | issue = Suppl 1 | pmid = 16112947 | doi = 10.1080/13697130500148875 | s2cid = 24616324 }}</ref> The medication is a [[prodrug]] of [[norethisterone]] in the body, with [[etynodiol]] occurring as an [[metabolic intermediate|intermediate]].<ref name="pmid16112947" /><ref name="pmid12215716" /><ref name="pmid2256526" /> |
|||
<!-- History, society and culture --> |
|||
After oral administration lynestrenol is quickly resorbed and converted into pharmacologically active norethisterone, through which it demonstrates the main biological effects. The peak blood are reached within 2–4 hours after oral administration, 97% of the administered dose being bound to plasma proteins. |
|||
Lynestrenol was discovered in the late 1950s and was introduced for medical use in 1961.<ref name="Gijswijt-HofstraHeteren2002" /><ref name="GaleResearch1991" /> It has mostly been used in [[Europe]] and elsewhere in the world and was never marketed in the [[United States]].<ref name="Drugs.com" /><ref name="LoboKelsey2000" /><ref name="Gelijns1991" /><ref name="FDA" /> |
|||
Lynestrenol and its metabolites are predominantly excreted in the urine, less through feces, active metabolite norethisterone elimination halftime being 16-17 h. |
|||
==Medical uses== |
|||
Lynestrenol is used as a component of [[oral contraceptive]]s in combination with an [[estrogen]] and is used in the treatment of [[gynecological disorder]]s such as [[menstrual disorder]]s.<ref name="MortonHall2012" /> |

In another approach to analogues, [[nortestosterone]] ('''1''') is first converted to the di[[thioketal]] ('''2''') by treatment with [[1,2-Ethanedithiol|dithioglycol]] in the presence of [[boron trifluoride]]. (The mild conditions of this reaction compared to those usually employed in preparing the oxygen ketals probably accounts for the double bond remaining at 4,5). Treatment of this derivative with sodium in liquid ammonia affords the 3-desoxy analog ('''3'''). Oxidation by means of [[Jones reagent]] followed by [[Alkynylation|ethynylation]] of the [[17-Ketosteroid|17-ketone]] leads to the orally active progestin ('''6'''). |
