This is an explanation of 2 highly specific reductive processes for the interconversion of primary PGs (prostaglandins). The laboratory procedures are described in detail and the chemical structures of substances involved in the process are diagrammed. A stereospecific reduction of PGE to PGFalpha is described.

Roles of Prostaglandin F Synthase
2001Prostaglandin (PG) F2 is widely distributed in various organs, and exhibits various biological actions such as smooth muscle contraction of uterus [1], bronchus [2], and trachea [3], the initiation of parturition [4], and pain transmission [5]. PGF synthase (PGFS) is a dual function enzyme, which catalyzes the reduction of not only PGD2 but also PGH2 ...

Possible role of prostaglandin F in blastocyst implantation
Prostaglandins, 1986The synthesis and release of Prostaglandin F (PGF) by the rabbit blastocyst and endometrium were investigated on Day 6 and Day 7, using radioimmunoassay, autoradiography and conversion experiments. The following results were obtained: The content of PGF in the blastocyst increased significantly (P less than 0.01) from Day 6 to Day 7. The content of PGF

The distribution of prostaglandins A, E, and F in the human kidney
Prostaglandins, 1974Abstract Using recently developed radioimmunoassay techniques, prostaglandin concentrations were measured in two human cadaver kidneys which had been processed for transplantation but for which no recipient patients could be obtained. Portions of cortex, medulla, papilla, and ureter were obtained from each kidney.

Identification of prostaglandin F-producing cells in the liver
Histochemistry and Cell Biology, 1999Prostaglandin (PG) F synthase forms PGF(2alpha) and 9alpha, 11beta-PGF2 from PGH2 and PGD2, respectively. PGH2 is synthesized from arachidonic acid by cyclooxygenase (COX) and then metabolized to various PGs and thromboxane by specific enzymes. PGD2 is synthesized from PGH2 by PGD synthase.

AbstractConcentrations of prostaglandin F and steroids in plasma and in corpus luteum (CL) were studied by radioimmunoassay during the luteal phase of the menstrual cycle in thirteen normal women.The average concentration of PGF in corpus luteum was 4.19 ± 1.59 ng/g (mean ± SE) (ranging from 0.03 to 20.5 ng/g) and in plasma was 208.1 ± 34.7 pg/ml ...

SummaryConcentrations of prostaglandin F (PGF) and its major circulating metabolite 13,14‐dihydro‐15‐keto‐PGF (PGFM) have been measured in amniotic fluid during spontaneous labour at term. Levels of both PGF and PGFM were significantly higher during early spontaneous labour, at a cervical dilatation of less than 4 cm, than before the onset of labour ...

The induction of abortion by prostaglandin F2α
American Journal of Obstetrics and Gynecology, 1971D u R I N G R EC E N T years, prostaglandin F,, and E, have been found to have a potent stimulating effect on the pregnant uterus. We have already reported our experience in using PGF,, for the induction of labor and the comparison of its effect with that of oxytocin in terms of uterine contractions.1 Now the possibility of using prostaglandin Fza (PGF&

Characterization of antibody to prostaglandin F2α
Biochemical and Biophysical Research Communications, 1972Abstract An antibody that reacted with PGF 2α was produced in two species (goat and rabbit) by injection of a Prostaglandin F 2α -Bovine Serum Albumin conjugate. Antibody binding was altered most by structural changes in the cyclopentane ring, and changes at the C-13,15 positions of the prostaglandin molecule.
