Prostaglandin E1
Prostaglandin E1 (PGE1) is a potent endogenous vasodilator agent that increases peripheral blood flow. It inhibits platelet aggregation and has many other biological effects such as bronchodilation, mediation of inflammation, and various protective functions. The protective action of PGE1 has been shown on both experimental animal models of liver injury and patients with fulminant viral hepatitis. PGE1-treated cirrhotic rats had less hepatosplenomegaly, lower serum alanine aminotransferase levels and portal pressures, and higher arterial pressure than placebo-treated cirrhotic rats. There are several mechanisms of PGE1 hepatic cytoprotection: inhibiting T-cell mediated cytotoxicity, enhancing DNA synthesis of the injured liver after partial hepatectomy by stimulating cyclic AMP production, increasing ATP level in hepatic tissue to accelerate the recovery of mitochondrial respiratory function after reperfusion, and stabilizing membrane microviscosity. PGE1 is a prostanoid. The term prostanoid collectively describes prostaglandins, prostacyclins, and thromboxanes. Prostanoids are a subclass of the lipid mediator group known as eicosanoids. They are derived from C-20 polyunsaturated fatty acids, mainly dihomo-γ-linolenic (20:3n-6), arachidonic (20:4n-6), and eicosapentaenoic (20:5n-3) acids, through the action of cyclooxygenases-1 and -2 (COX-1 and COX-2) (PMID: 11819590, 16986207). Prostaglandins are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent and are able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis through receptor-mediated G-protein linked signalling pathways. Prostaglandin E1 (Alprostadil) is a prostanoid receptor ligand, with Kis of 1.1 nM, 2.1 nM, 10 nM, 33 nM and 36 nM for mouse EP3, EP4, EP2, IP and EP1, respectively. Prostaglandin E1 induces vasodilation and inhibits platelet aggregation. Prostaglandin E1 can be used as a vasodilator for the research of peripheral vascular diseases[1][2][3].
Prostaglandin F1a
Prostaglandin F1a is derived mainly from Prostaglandin E1, and is metabolized to 6-Keto Prostaglandin F1a. Prostaglandin F1a is excreted directly into the urine. Prostaglandin F1a contracts the circular muscle of the gut in opposition to the Prostaglandins of the E series. Prostaglandin F1a is a cytoprotector, protecting mucosal tissue from damage produced by ulcerogenic stimuli.Prostaglandins are eicosanoids.

Prostaglandin D3
Prostaglandin D3 (PGD3) is a prostanoid that has been identified as an inhibitor of human platelet aggregation and as a modulator of autonomic nerve transmission. Prostanoids are a subclass of the lipid mediator group known as eicosanoids. They derive from C-20 polyunsaturated fatty acids, mainly dihomo-gamma-linoleic (20:3n-6), arachidonic (20:4n-6), and eicosapentaenoic (20:5n-3) acids, through the action of cyclooxygenases-1 and -2 (COX-1 and COX-2). The reaction product of COX is the unstable endoperoxide prostaglandin H (PGH) that is further transformed into the individual prostanoids by a series of specific prostanoid synthases. Prostanoids are local-acting mediators formed and inactivated within the same or neighbouring cells prior to their release into circulation as inactive metabolites (15-keto- and 13,14-dihydroketo metabolites). Non-enzymatic peroxidation of arachidonic acid and other fatty acids in vivo can result in prostaglandin-like substances isomeric to the COX-derived prostaglandins that are termed isoprostanes. Prostanoids take part in many physiological and pathophysiological processes in practically every organ, tissue and cell, including the vascular, renal, gastrointestinal and reproductive systems. Their activities are mediated through prostanoid-specific receptors and intracellular signalling pathways, whilst their biosynthesis and action are blocked by nonsteroidal antiinflammatory drugs (NSAID). Isoprostanes are considered to be reliable markers of oxidant stress status and have been linked to inflammation, ischaemia-reperfusion, diabetes, cardiovascular disease, reproductive disorders and diabetes.
