prostaglandin f-1α

Prostaglandin F1α (PGF1α) is the putative metabolite of dihomo-γ-linolenic acid (DGLA) via the cyclooxygenase (COX) pathway. Both PGF1α and PGF2α have been shown to act as priming pheromones for male Atlantic salmon with a threshold concentration of 10-11 M. [1] PGF1α binds to the ovine corpus luteum FP receptor at only 8% of the relative potency of PGF2α. [2] It is only half as active as PGF2α in inducing human respiratory smooth muscle contractions in vitro. [3]

PGF1β, a biochemical compound, functions as a pivotal mediator in inflammatory processes and plays an integral role in uterine contractions. It exhibits significant regulatory effects on platelet aggregation and vasodilation, demonstrating its critical importance in cardiovascular health. Additionally, PGF1β contributes to the regulation of kidney function and electrolyte balance, illustrating its widespread impact across various physiological systems.

11-deoxy PGF1α is a synthetic analog of PGF1α. In whole animal studies, a dose of 32 mg/kg inhibited gastric acid secretion by 35%. 11-deoxy PGF1α is also known to cause rat uterine contractions at a dose 0.3 times that of PGF1α. It also exhibits vasopressor and bronchoconstrictor activities at about half the potency of PGF2α in guinea pigs.

15-keto PGF1α is the initial metabolite of PGF1α via 15-hydroxy PGDH. In mammals, oxidation of C-15 markedly attenuates receptor binding and activity. In fish, the 15-keto compounds serve as post-ovulatory pheromones and are more active than the parent prostaglandins.

8-iso Prostaglandin F1α is an isoprostaglandin produced from arachidonic acid that induces concentration-dependent vasoconstrictor effects in pulmonary arteries (PA), pulmonary veins (PV) and mesenteric arteries (MA) through activation of TXA2R, tyrosine kinases and Rho kinases.

13,14-dihydro-15-keto Prostaglandin F1α (13,14-dihydro-15-keto PGF1α) is a metabolite of PGF1α that has been reported in the rat stomach. The measurement of 13,14-dihydro-15-keto PGF1α can be used as a marker of the in vivo production of PGF1α.

6,15-diketo-13,14-dihydro PGF1α is a metabolite of PGI2. It was shown to enhance intracellular cAMP and cholesterol catabolism in bovine arterial smooth muscle cells.
