prostaglandin f1alpha

Prostaglandin F1α(PGF1α)是一种脂质介质和prostacyclin的内源性代谢物，主要由DGLA经过COX途径代谢生成，能够剂量依赖性地调节平滑肌收缩。

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。

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.

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.

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.
