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.

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.

8-iso Prostaglandin F1α（8-异前列腺素 F1α）是一种由花生四烯酸产生的异前列腺素，能引起浓度依赖性的的血管收缩效应，包括肺动脉（PA）、肺静脉（PV）和肠系膜动脉（MA），通过TXA2R、酪氨酸激酶和Rho激酶的激活。

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.

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.

17-TFM-PGF1α (Compound 8) 为一种饱和前列腺素类似物。此化合物对人前列腺素 F 受体 (hFP receptor) 表现出较强的亲和性和受体选择性，其EC50为 85 nM。

8-iso Prostaglandin F1β（8-异前列腺素 F1β）是一种由花生四烯酸产生的异前列腺素，能引起浓度依赖性的的血管收缩效应，包括肺动脉（PA）、肺静脉（PV）和肠系膜动脉（MA），通过TXA2R、酪氨酸激酶和Rho激酶的激活。

11-deoxy PGF1β is a synthetic analog of PGF1β. In contrast to PGF2α and PGF1α, 11-deoxy PGF1β exhibits vasodepressor and bronchodilator activities in guinea pigs at a dose of 500 μg kg.

2,3-dinor-8-iso Prostaglandin F1α（2,3-dinor-8-iso PGF1α）是一种异前列腺素和花生四烯酸的活性代谢物，也是血小板聚集抑制剂8-iso PGF2α的产物。它通过花生四烯酸的非酶促自由基过氧化作用形成。2,3-dinor-8-iso PGF1α在孤立的猪视网膜和大脑微血管中引起血管收缩（EC50s分别为12.8和18.5 nM），但在31 µM的浓度下使用时不会引起孤立的大鼠主动脉环的收缩。在1 µM的浓度下使用时，它能增加孤立的猪大脑切片中的血栓素B2（TXB2）水平，这一效应可以通过血栓素A合成酶抑制剂CGS 12970、电压门控钙通道抑制剂SKF 96365或烟碱型乙酰胆碱受体（nAChR）拮抗剂α-conotoxin来逆转。

Δ17-6-keto Prostaglandin F1α (Δ17-6-keto PGF1α), a cyclooxygenase (COX) metabolite produced from eicosapentaenoic acid (EPA) in a variety of tissues including seminal vesicles, lungs, polymorphonuclear leukocytes, and ocular tissues, alongside other 3-series COX products from EPA such as PGF3α, PGE3, and thromboxane B3, is potentially linked to a lower occurrence of glaucoma in individuals consuming a marine-rich (EPA-rich) diet.
