Prostaglandin F2α

This article is about the pharmaceutical agent 'dinoprost'. For the drug 'dinoprostone', see Prostaglandin E2.

Prostaglandin F (PGF in prostanoid nomenclature), pharmaceutically termed dinoprost (INN), is a naturally occurring prostaglandin used in medicine to induce labor and as an abortifacient.

In domestic mammals, it is produced by the uterus when stimulated by oxytocin, in the event that there has been no implantation during the follicular phase. It acts on the corpus luteum to cause luteolysis, forming a corpus albicans and stopping the production of progesterone. Action of PGF is dependent on the number of receptors on the corpus luteum membrane.

The PGF isoform 8-iso-PGF was found in significantly increased amounts in patients with endometriosis, thus being a potential causative link in endometriosis-associated oxidative stress.[1]

Mechanism of action

PGF acts by binding to the prostaglandin F2α receptor.

Synthesis

In 2012 a concise and highly stereoselective total synthesis of PGF has been described.[2] The synthesis requires only seven steps, a huge improvement on the original 17-steps synthesis of Corey and Cheng,[3] and uses 2,5-dimethoxytetrahydrofuran as a starting reagent, with S-proline as an asymmetric catalyst.

Analogs

The following medications are analogs of prostaglandin F:
