Description
Prostaglandin F2α (PGF2α) is a widely distributed PG occurring in many species. It causes contraction of vascular, bronchial, intestinal, and myometrial smooth muscle, and also exhibits potent luteolytic activity. PGF2α exerts its receptor mediated physiological activity at 50-100 nM. Maximal ovine myometrial contraction can be achieved at 125 nM PGF2α in vitro.
History
Prostaglandins (PGs) are a class of important endogenous products with a wide range of physiological activities. PGs were first discovered and named by American scholar Von Eluer in 1930. In 1962, Bergstorm extracted two pure PGs (PGF1 and PGF2) and determined their chemical structures. In 1969, Willis first proposed that PGs are an inflammatory mediator in the body. Subsequently, various physiological and pharmacological activities of PGs have been intensively studied.
Uses
Prostaglandin F2α is one of the most biologically studied of the primary prostaglandins. Closely related to Prostaglandin E2 (PGE2) in that both prostaglandins are biosynthesized from the same precursors and that PGF2 is the synthetic reduction product of PGE2.
Definition
ChEBI: Prostaglandin F2α is a prostaglandins Falpha that is prosta-5,13-dien-1-oic acid substituted by hydroxy groups at positions 9, 11 and 15. It is a naturally occurring prostaglandin used to induce labor.
Pharmacokinetics
Dinoprost is a natural prostaglandin F2α (PGF2α), which can directly act on the myometrium, stimulate the pregnant uterus to contract the uterine muscle, and can soften and dilate the cervix, so it can be used for induced abortion and late labor induction. However, due to the instability of dinoprost at room temperature, inconvenient storage and transportation, complex synthesis process and high cost, the application of dinoprost is difficult to popularize.
Safety Profile
Poison by subcutaneous, intravenous, and intramuscular routes. Moderately toxic by ingestion. Human and experimental teratogenic and experimental reproductive effects. Human reproductive effects by subcutaneous, intravenous, intramuscular, intraperitoneal, intravaginal, and intraplacental routes: postpartum depression and other maternal effects, abortion, and changes in measures of ferulity. Human teratogenic effects by intraplacental route: extra embryonic structures. Human systemic effects by intravenous route: hypermoulity, diarrhea, nausea or vomiting. Human mutation data reported. When heated to decomposition it emits acrid smoke and fumes
Check Digit Verification of cas no
The CAS Registry Mumber 551-11-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 551-11:
(5*5)+(4*5)+(3*1)+(2*1)+(1*1)=51
51 % 10 = 1
So 551-11-1 is a valid CAS Registry Number.

Concise, scalable and enantioselective total synthesis of prostaglandins

Prostaglandins are among the most important natural isolates owing to their broad range of bioactivities and unique structures. However, current methods for the synthesis of prostaglandins suffer from low yields and lengthy steps. Here, we report a practicability-oriented synthetic strategy for the enantioselective and divergent synthesis of prostaglandins. In this approach, the multiply substituted five-membered rings in prostaglandins were constructed via the key enyne cycloisomerization with excellent selectivity (>20:1 d.r., 98% e.e.). The crucial chiral centre on the scaffold of the prostaglandins was installed using the asymmetric hydrogenation method (up to 98% yield and 98% e.e.). From our versatile common intermediates, a series of prostaglandins and related drugs could be produced in two steps, and fluprostenol could be prepared on a 20-gram scale.

The asymmetric total synthesis of PGF2α and 6,15-diketo-PGF1α and formal synthesis of 6-keto-PGF1α from a common key intermediate are described. The key intermediate, which has a chiral cyclopentane backbone possessing suitable functional groups with required stereochemistry for both side chains, was prepared from (R)-4-silyloxy-2-cyclopentenone through a three-component coupling reaction. The Wittig reaction, Nozaki-Hiyama-Kishi (NHK) coupling and cross metathesis completed the synthesis of PGF2α, 6,15-diketo-PGF1α and 6-keto-PGF1α.
