Prostaglandin E2
The naturally occurring prostaglandin E2 (PGE2) is known in medicine as dinoprostone, and it is the most common and most biologically active of the mammalian prostaglandins. It has important effects during labour and also stimulates osteoblasts to release factors which stimulate bone resorption by osteoclasts (a type of bone cell that removes bone tissue by removing the bones mineralized matrix). PGE2 is also the prostaglandin that ultimately induces fever. PGE2 has been shown to increase vasodilation and cAMP production, enhance the effects of bradykinin and histamine, and induce uterine contractions and platelet aggregation. PGE2 is also responsible for maintaining the open passageway of the fetal ductus arteriosus, decreasing T-cell proliferation and lymphocyte migration, and activating the secretion of IL-1α and IL-2. PGE2 exhibits both pro- and anti-inflammatory effects, particularly on dendritic cells (DC). Depending on the nature of maturation signals, PGE2 has different and sometimes opposite effects on DC biology. PGE2 exerts an inhibitory action, reducing the maturation of DC and their ability to present antigen. PGE2 has also been shown to stimulate DC and promote IL-12 production when given in combination with TNF-alpha. PGE2 is an environmentally bioactive substance. Its action is prolonged and sustained by other factors especially IL-10. It modulates the activities of professional DC by acting on their differentiation, maturation, and their ability to secrete cytokines. PGE2 is a potent inducer of IL-10 in bone marrow-derived DC (BM-DC). PGE2-induced IL-10 is a key regulator of the BM-DC pro-inflammatory phenotype (PMID:16978535). 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.

Lipoxin A4
Lipoxin A4 (LXA4) was first identified in 1984 by Serhan and colleagues as 5-lipoxygenase interaction product of activated leukocytes. Endogenous transcellular biosynthesis of LXA4 occurs via interaction of leukocytes with epithelium, endothelium or platelets. Lipoxins (LXs) or the lipoxygenase interaction products are generated from arachidonic acid via sequential actions of lipoxygenases and subsequent reactions to give specific trihydroxytetraene-containing eicosanoids. These unique structures are formed during cell-cell interactions and appear to act at both temporal and spatially distinct sites from other eicosanoids produced during the course of inflammatory responses and to stimulate natural resolution. Lipoxin A4 (LXA4) and lipoxin B4 (LXB4) are positional isomers that each possesses potent cellular and in vivo actions. These LX structures are conserved across species. The results of numerous studies reviewed in this work now confirm that they are the first recognized eicosanoid chemical mediators that display both potent anti-inflammatory and pro-resolving actions in vivo in disease models that include rabbit, rat, and mouse systems. LXs act at specific GPCRs as agonists to regulate cellular responses of interest in inflammation and resolution. Aspirin has a direct impact in the LX circuit by triggering the biosynthesis of endogenous epimers of LX, termed the aspirin-triggered 15-epi-LX, that share the potent anti-inflammatory actions of LX.

Prostaglandin D2
Prostaglandin D2 (or PGD2) is a prostaglandin that is actively produced in various organs such as the brain, spleen, thymus, bone marrow, uterus, ovary, oviduct, testis, prostate and epididymis, and is involved in many physiological events. PGD2 binds to the prostaglandin D2 receptor (PTGDR) which is a G-protein-coupled receptor. Its activity is mainly mediated by G-S proteins that stimulate adenylate cyclase resulting in an elevation of intracellular cAMP and Ca2+. PGD2 promotes sleep; regulates body temperature, olfactory function, hormone release, and nociception in the central nervous system; prevents platelet aggregation; and induces vasodilation and bronchoconstriction. PGD2 is also released from mast cells as an allergic and inflammatory mediator. Prostaglandin H2 is an unstable intermediate formed from PGG2 by the action of cyclooxygenase (COX) in the arachidonate cascade. In mammalian systems, it is efficiently converted into more stable arachidonate metabolites, such as PGD2, PGE2, PGF2a by the action of three groups of enzymes, PGD synthases (PGDS), PGE synthases and PGF synthases, respectively. PGDS catalyzes the isomerization of PGH2 to PGD2. Two types of PGD2 synthase are known. Lipocalin-type PGD synthase is present in cerebrospinal fluid, seminal plasma and may play an important role in male reproduction. Another PGD synthase, hematopoietic PGD synthase is present in the spleen, fallopian tube, endometrial gland cells, extravillous trophoblasts and villous trophoblasts, and perhaps plays an important role in female reproduction. Recent studies demonstrate that PGD2 is probably involved in multiple aspects of inflammation through its dual receptor systems, DP and CRTH2. (PMID:12148545)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.

Prostaglandin I2
Prostaglandin I2 or prostacyclin (or PGI2) is a member of the family of lipid molecules known as eicosanoids. It is produced in endothelial cells from prostaglandin H2 (PGH2) by the action of the enzyme prostacyclin synthase. It is a powerful vasodilator and inhibits platelet aggregation. Prostaglandin I2 is the main prostaglandin synthesized by the blood vessel wall. This suggests that it may play an important role in limiting platelet-mediated thrombosis. In particular, prostacyclin (PGI2) chiefly prevents formation of the platelet plug involved in primary hemostasis (a part of blood clot formation). The sodium salt (known as epoprostenol) has been used to treat primary pulmonary hypertension. Prostacyclin (PGI2) is released by healthy endothelial cells and performs its function through a paracrine signaling cascade that involves G protein-coupled receptors on nearby platelets and endothelial cells. The platelet Gs protein-coupled receptor (prostacyclin receptor) is activated when it binds to PGI2. This activation, in turn, signals adenylyl cyclase to produce cAMP. cAMP goes on to inhibit any undue platelet activation (in order to promote circulation) and also counteracts any increase in cytosolic calcium levels which would result from thromboxane A2 (TXA2) binding (leading to platelet activation and subsequent coagulation). PGI2 also binds to endothelial prostacyclin receptors and in the same manner raise cAMP levels in the cytosol. This cAMP then goes on to activate protein kinase A (PKA). PKA then continues the cascade by inhibiting myosin light-chain kinase which leads to smooth muscle relaxation and vasodilation. Notably, PGI2 and TXA2 work as antagonists. PGI2 is stable in basic buffers (pH=8), but it is rapidly hydrolyzed to 6-keto PGF1alpha in neutral or acidic solutions. The half-life is short both in vivo and in vitro, ranging from 30 seconds to a few minutes. PGI2 is administered by continuous infusion in humans for the treatment of idiopathic pulmonary hypertension.Prostaglandins are eicosanoids.

Prostaglandin H2
Prostaglandin H2 (PGH2) is the first intermediate in the biosynthesis of all prostaglandins. Prostaglandins are synthesized from arachidonic acid by the enzyme COX-1 and COX-2, which are also called PGH synthase 1 and 2. These enzymes generate a reactive intermediate PGH2 which has a reasonably long half-life (90-100 s) but is highly lipophilic. PGH2 is converted into the biologically active prostaglandins by prostaglandin isomerases, yielding PGE2, PGD2, and PGF2, or by thromboxane synthase to make TXA2 or by prostacyclin synthase to make PGI2. Most nonsteroidal anti-inflammatory drugs such as aspirin and indomethacin inhibit both PGH synthase 1 and 2. A key feature for eicosanoid transcellular biosynthesis is the export of PGH2 or LTA4 from the donor cell as well as the uptake of these reactive intermediates by the acceptor cell. Very little is known about either process despite the demonstrated importance of both events. In cells, PGH2 rearranges nonenzymatically to LGs even in the presence of enzymes that use PGH2 as a substrate. When platelets form thromboxane A2 (TXA2) from endogenous arachidonic acid (AA), PGH2 reaches concentrations very similar to those of TXA2 and high enough to produce strong platelet activation. Therefore, platelet activation by TXA2 appears to go along with an activation by PGH2. The agonism of PGH2 is limited by the formation of inhibitory prostaglandins, especially PGD2 at higher concentrations. That is why thromboxane synthase inhibitors in PRP and at a physiological HSA concentration do not augment platelet activation (PMID: 2798452, 15650407, 16968946). 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 h2, also known as pgh2 or 9s,11r-epidioxy-15s-hydroxy-5z,13e-prostadienoate, is a member of the class of compounds known as prostaglandins and related compounds. Prostaglandins and related compounds are unsaturated carboxylic acids consisting of a 20 carbon skeleton that also contains a five member ring, and are based upon the fatty acid arachidonic acid. Thus, prostaglandin h2 is considered to be an eicosanoid lipid molecule. Prostaglandin h2 is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Prostaglandin h2 can be found in a number of food items such as gooseberry, evergreen huckleberry, quince, and capers, which makes prostaglandin h2 a potential biomarker for the consumption of these food products. Prostaglandin h2 can be found primarily in human platelet tissue. In humans, prostaglandin h2 is involved in several metabolic pathways, some of which include magnesium salicylate action pathway, ketorolac action pathway, trisalicylate-choline action pathway, and salicylate-sodium action pathway. Prostaglandin h2 is also involved in a couple of metabolic disorders, which include leukotriene C4 synthesis deficiency and tiaprofenic acid action pathway. Prostaglandin h2 is acted upon by: Prostacyclin synthase to create prostacyclin Thromboxane-A synthase to create thromboxane A2 and 12-(S)-hydroxy-5Z,8E,10E-heptadecatrienoic acid (HHT) (see 12-Hydroxyheptadecatrienoic acid) Prostaglandin D2 synthase to create prostaglandin D2 Prostaglandin E synthase to create prostaglandin E2 Prostaglandin h2 rearranges non-enzymatically to: A mixture of 12-(S)-hydroxy-5Z,8E,10E-heptadecatrienoic acid (HHT) and 12-(S)-hydroxy-5Z,8Z,10E-heptadecatrienoic acid (see 12-Hydroxyheptadecatrienoic acid) Use of Prostaglandin H2: regulating the constriction and dilation of blood vessels stimulating platelet aggregation Effects of Aspirin on Prostaglandin H2: Aspirin has been hypothesized to block the conversion of arachidonic acid to Prostaglandin .

15-Keto-prostaglandin F2a

PGF2 is mainly synthesized directly from PGH2 by PGH2 9,11-endoperoxide reductase. A small amount of PGF2 is also produced from PGE2 by PGE2 9-ketoreductase.

Lipoxin B4
Lipoxins (LXs) and aspirin-triggered lipoxin (ATL) are trihydroxytetraene-containing eicosanoids generated from arachidonic acid that are distinct in structure, formation, and function from the many other proinflammatory lipid-derived mediators. These endogenous eicosanoids have now emerged as founding members of the first class of lipid/chemical mediators involved in the resolution of the inflammatory response. Lipoxin A4 (LXA4), ATL, and their metabolic stable analogs elicit cellular responses and regulate leukocyte trafficking in vivo by activating the specific receptor, ALX. Many of the eicosanoids derived from arachidonic acid (AA2), including prostaglandins (PGs) and leukotrienes (LTs), play important roles as local mediators exerting a wide range of actions relevant in immune hypersensitivity and inflammation. However, recent observations indicate that other agents derived from the lipoxygenase (LO) pathways are formed and play a key role in initiating the resolution of acute inflammation. This phenomenon is an active process that is governed by specific lipid mediators and involves a series of well-orchestrated temporal events. Thus, potent locally released mediators serve as checkpoint controllers of inflammation. In addition to the well-appreciated ability of aspirin to inhibit PGs, aspirin also acetylates cyclooxygenase (COX)-2, triggering the formation of a 15-epimeric form of lipoxins, termed aspirin-triggered LXA4 (ATL). These eicosanoids (i.e. LXA4 and ATL) with a unique trihydroxytetraene structure function as stop signals in inflammation and actively participate in dampening host responses to bring the inflammation to a close, namely, resolution. LXA4 and ATL elicit the multicellular responses via a specific G protein-coupled receptor (GPCR) termed ALX that has been identified in human (PMID: 16968948, 11478982).

This phenomenon is an active process that is governed by specific lipid mediators and involves a series of well-orchestrated temporal events. Thus, potent locally released mediators serve as checkpoint controllers of inflammation.

Prostaglandin F3a
Prostaglandin F3alpha (PGF3a) is a prostanoid. Prostanoids is a term that collectively describes prostaglandins, prostacyclines and thromboxanes. 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. (PMID: 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, 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 F3alpha (PGF3a) is a prostanoid.

Levuglandin E2
Levuglandin E2 is a levuglandin generated in the cyclooxygenase (COX) pathway. Levuglandins (LGs) and their stereo and structural isomers are extraordinarily reactive γ-ketoaldehydes that are generated by rearrangements of prostanoid endoperoxide intermediates of polyene cyclooxygenation. Their rapid adduction with biological nucleophiles results, inter alia, in pathological modifications of proteins and DNA. It also complicates their detection. Cyclooxygenase-promoted lipid oxidation is a pivotal step in the biosynthesis of an array of physiologically active metabolites. COX fosters a highly regio and stereoselective cyclooxygenation of arachidonic acid (AA) to deliver a single, enantiomerically pure endoperoxide, PGH2, that is a branch point in the biosynthesis of numerous hormone-like mediators of cellular activities. Spontaneous rearrangements of PGH2 were known to generate prostaglandins (PG) PGD2 and PGE2. (PMID: 15752459) [HMDB] Levuglandin E2 is a levuglandin generated in the cyclooxygenase (COX) pathway.

20-Hydroxy-leukotriene B4
20-hydroxy- Leukotriene B4 (20-OH-LTB4) is an omega-hydroxylated metabolite of leukotriene B4 in human neutrophils. Elevated urinary concentrations of 20-OH-LTB4 and LTB4 are found in patients with Sjogren-Larsson syndrome (SLS, OMIM 270220), an autosomal recessively inherited neurocutaneous disorder caused by a deficiency of the microsomal enzyme fatty aldehyde dehydrogenase (FALDH), which as an essential role in LTB4 metabolism. Preterm birth seems to be one of the features of the syndrome. The reason for the preterm birth is unclear. It is hypothesized that it relates to the defective LTB4 degradation in SLS. The pathological urinary excretion of LTB4 and 20-OH-LTB4 is a biochemical marker for SLS. Surprisingly, 20-OH-LTB4 concentrations are normal in CSF. Leukotriene B4 is the major metabolite in neutrophil polymorphonuclear leukocytes. Leukotrienes are metabolites of arachidonic acid derived from the action of 5-LO (5-lipoxygenase). The immediate product of 5-LO is LTA4 (leukotriene A4), which is enzymatically converted into either LTB4 (leukotriene B4) by LTA4 hydrolase or LTC4 (leukotriene C4) by LTC4 synthase. The regulation of leukotriene production occurs at various levels, including expression of 5-LO, translocation of 5-LO to the perinuclear region and phosphorylation to either enhance or inhibit the activity of 5-LO. Biologically active LTB4 is metabolized by w-oxidation carried out by specific cytochrome P450s (CYP4F) followed by beta-oxidation from the w-carboxy position and after CoA ester formation. Other specific pathways of leukotriene metabolism include the 12-hydroxydehydrogenase/ 15-oxo-prostaglandin-13-reductase that form a series of conjugated diene metabolites that have been observed to be excreted into human urine. Metabolism of LTC4 occurs by sequential peptide cleavage reactions involving a gamma-glutamyl transpeptidase that forms LTD4 (leukotriene D4) and a membrane-bound dipeptidase that converts LTD4 into LTE4 (leukotriene E4) before w-oxidation. These metabolic transformations of the primary leukotrienes are critical for termination of their biological activity, and defects in expression of participating enzymes may be involved in specific genetic disease. (PMID: 12709426, 9799565, 11408337, 17623009). Leukotrienes are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs).

Thromboxane A2
Thromboxane A2 is an unstable intermediate between the prostaglandin endoperoxides and thromboxane B2. The compound has a bicyclic oxaneoxetane structure. It is a potent inducer of platelet aggregation and causes vasoconstriction. It is the principal component of rabbit aorta contracting substance (RCS).Thromboxanes 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.

13,14-Dihydro-15-keto-PGE2
13,14-dihydro-15-keto-PGE2 is one of the prostaglandin E2 metabolites. (PMID 7190512) Human fetal lung in vitro has the competence to self-differentiate, as early as 12 weeks gestation and presence of high levels in fetal lung of the inactive metabolite 13,14-dihydro-15-keto-PGE2 relative to PGE2 suggests that active prostaglandin catabolism may be one of the mechanisms to retard this stage of maturation in vivo by limiting PGE2 availability. (PMID 8835315)Dinoprostone is a naturally occurring prostaglandin E2 (PGE2) and the most common and most biologically active of the mammalian prostaglandins. It has important effects in labour and also stimulates osteoblasts to release factors which stimulate bone resorption by osteoclasts (a type of bone cell that removes bone tissue by removing the bones mineralized matrix). PGE2 has been shown to increase vasodilation and cAMP production, to enhance the effects of bradykinin and histamine, to induce uterine contractions and to activate platelet aggregation. PGE2 is also responsible for maintaining the open passageway of the fetal ductus arteriosus; decreasing T-cell proliferation and lymphocyte migration and activating the secretion of IL-1alpha and IL-2. PGE2 exhibits both pro- and anti-inflammatory effects, particularly on dendritic cells (DC). Depending on the nature of maturation signals, PGE2 has different and sometimes opposite effects on DC biology. PGE2 exerts an inhibitory action, reducing the maturation of DC and their ability to present antigen. PGE2 has also been shown to stimulate DC and promote IL-12 production when given in combination with TNF-alpha. PGE2 is an environmentally bioactive substance. Its action is prolonged and sustained by other factors especially IL-10. It modulates the activities of professional DC by acting on their differentiation, maturation and their ability to secrete cytokines. PGE2 is a potent inducer of IL-10 in bone marrow-derived DC (BM-DC), and PGE2-induced IL-10 is a key regulator of the BM-DC pro-inflammatory phenotype. (PMID: 16978535)Prostaglandins are eicosanoids.

13,14-dihydro-15-keto Prostaglandin D2 (13,14-dihydro-15-keto PGD2), (CAS 59894-07-4), is a metabolite of PGD2 which is formed through the 15-hydroxy PGDH pathway. 13,14-dihydro-15-keto PGD2 was recently identified as a selective agonist for the CRTH2/DP2 receptor. It also inhibits ion flux in a canine colonic mucosa preparation. In humans, 13,14-dihydro-15-keto PGD2 is further metabolized to give 11β-hydroxy compounds which have also undergone β-oxidation of one or both side chains. Virtually no 13,14-dihydro-15-keto PGD2 survives intact in the urine. (http://www.caymanchem.com)
8-iso-PGF3a
8-iso-PGF3alpha is an isoprostane with an antiaggregatory action in human blood. Isoprostanes (IsoPs) are formed in vivo from the free radical-catalyzed peroxidation of arachidonate independent of cyclooxygenase (COX). Although the structures of these compounds are very similar to COX-derived prostaglandins (PGs), an important distinction between IsoPs and PGs is that IsoP bicycloendoperoxide intermediates contain side chains that are predominantly (>90\\%) oriented cis in relation to the prostane ring because the generation of these intermediates is favored kinetically. In contrast to other types of prostanoids, E2/D2-IsoPs are beta-hydroxyketone-containing compounds that can undergo reversible keto-enol tautomerization under both acidic and basic conditions, allowing rearrangement of the side chains that are initially cis to the more stable trans-configuration.

8-iso-15-keto-PGF2a
8-iso-15-keto-PGF2alpha is an isoprostane. Isoprostanes are produced during peroxidation of membrane lipids by free radicals and reactive oxygen species, and are currently used as markers of many disease states and experimental conditions in which oxidative stress is a prominent feature. A small number of reports have described the ability of some isoprostanes to evoke important biological effects in smooth muscle and other cell types. There is a long (and growing) list of disease states and pathophysiological conditions which are associated with marked elevation in the levels of iso- prostanes. For example, measured levels of the plasma, urine, bronchoalveolar lavage fluid, and/or tissues of smokers, patients with asthma chronic obstructive pulmonary disease, interstitial lung disease, cystic fibrosis, or acute chest syndrome, during exposure to allergen, ozone or hyperoxia; and during ventilated ischemia. Likewise, cardiovascular conditions such as renal, myocardial, ischemia-reperfusion injury, atherosclerosis, and pre-eclampsia are also indicated by a marked elevation of plasma/urinary levels of isoprostanes.

13,14-Dihydro-15-oxo-lipoxin A4
13,14-dihydro-15-oxo-lipoxin A4 is a lipoxin derivative. Lipoxins (LXs) and aspirin-triggered Lipoxin (ATL) are trihydroxytetraene-containing eicosanoids generated from arachidonic acid that are distinct in structure, formation, and function from the many other proinflammatory lipid-derived mediators. These endogenous eicosanoids have now emerged as founding members of the first class of lipid/chemical mediators involved in the resolution of the inflammatory response. Lipoxin A4 (LXA4), ATL, and their metabolic stable analogs elicit cellular responses and regulate leukocyte trafficking in vivo by activating the specific receptor, ALX. Many of the eicosanoids derived from arachidonic acid (AA2), including prostaglandins (PGs) and leukotrienes (LTs), play important roles as local mediators exerting a wide range of actions relevant in immune hypersensitivity and inflammation. However, recent observations indicate that other agents derived from the lipoxygenase (LO) pathways are formed and play a key role in initiating the resolution of acute inflammation. This phenomenon is an active process that is governed by specific lipid mediators and involves a series of well-orchestrated temporal events. Thus, potent locally released mediators serve as checkpoint controllers of inflammation. In addition to the well-appreciated ability of aspirin to inhibit PGs, aspirin also acetylates cyclooxygenase (COX)-2, triggering the formation of a 15-epimeric form of lipoxins, termed aspirin-triggered LXA4 (ATL). These eicosanoids (i.e., LXA4 and ATL) with a unique trihydroxytetraene structure function as stop signals in inflammation and actively participate in dampening host responses to bring the inflammation to a close, namely, resolution. LXA4 and ATL elicit the multicellular responses via a specific G protein-coupled receptor (GPCR) termed ALX that has been identified in human.

Lipoxins (LXs) and aspirin-triggered Lipoxin (ATL) are trihydroxytetraene-containing eicosanoids generated from arachidonic acid that are distinct in structure, formation, and function from the many other proinflammatory lipid-derived mediators. These endogenous eicosanoids have now emerged as founding members of the first class of lipid/chemical mediators involved in the resolution of the inflammatory response. Lipoxin A4 (LXA4), ATL, and their metabolic stable analogs elicit cellular responses and regulate leukocyte trafficking in vivo by activating the specific receptor, ALX. Many of the eicosanoids derived from arachidonic acid (AA2), including prostaglandins (PGs) and leukotrienes (LTs), play important roles as local mediators exerting a wide range of actions relevant in immune hypersensitivity and inflammation. However, recent observations indicate that other agents derived from the lipoxygenase (LO) pathways are formed and play a key role in initiating the resolution of acute inflammation. This phenomenon is an active process that is governed by specific lipid mediators and involves a series of well-orchestrated temporal events. Thus, potent locally released mediators serve as checkpoint controllers of inflammation. In addition to the well-appreciated ability of aspirin to inhibit PGs, aspirin also acetylates cyclooxygenase (COX)-2, triggering the formation of a 15-epimeric form of lipoxins, termed aspirin-triggered LXA4 (ATL). These eicosanoids (i.e., LXA4 and ATL) with a unique trihydroxytetraene structure function as stop signals in inflammation and actively participate in dampening host responses to bring the inflammation to a close, namely, resolution. LXA4 and ATL elicit the multicellular responses via a specific G protein-coupled receptor (GPCR) termed ALX that has been identified in human.

11b-PGE2
11b-PGE2 is a prostaglandins. 15-series prostaglandins (PGE2) and isoprostanes (isoPGE2) are robust biomarkers of oxidative stress, possess potent biological activity, and may be derived through cyclooxygenase or free radical pathways. Thus, their quantification is critical in understanding many biological process. Major brain PGE2/PGD2/isoPGE2 includes PGE2, entPGE2, 8-isoPGE2, 11b-PGE2, PGD2, and 15(R)-PGD2. (PMID: 21317107)
