Andrographolide is a labdane diterpenoid that is produced by the Andrographis paniculata plant, which has a broad range of therapeutic applications including anti-inflammatory and anti-platelet aggregation activities and potential antineoplastic properties. Since andrographolide has multiple therapeutic activities there are several proposed mechanisms of action for this agent. The anti-inflammatory effects of this agent appear to be related to the inhibition of nitric oxide (NO) production by macrophages. This agent may activate the NO/cyclic GMP pathway and inhibit both the phospholipase C gamma 2 (PLC gamma2)/protein kinase C (PKC) and PI3K/AKT-MAPK signaling pathways in activated platelets to inhibit platelet aggregation. In activated platelets, these three signaling pathways are downstream of integrin activation mediated by collagen binding and influence the association of fibrinogen with its receptors. Additionally, andrographolide may exert its anti-cancer activity through the induction of cell cycle arrest at G0/G1 phase and the stimulation of lymphocyte proliferation and activation. These processes could result in decreased proliferation of and increased immunocytotoxicity against tumor cells.

The enzyme that catalyzes the conversion of alcohols to aldehydes is a zinc-containing dimeric enzyme responsible for the oxidation of long-chain alcohols and omega-hydroxy fatty acids. (OMIM) 12-Hydroxydodecanoic acid is an endogenous metabolite.
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.

8-HETE
8(S)-HETE is a naturally occurring hydroxyeicosatetraenoic acid eicosanoid. 8(S)-HETE is a strong activator of peroxisome proliferator-activated receptors (PPARs) alpha and a weak activator of PPAR gamma. PPARs are nuclear hormone receptors that regulate gene transcription in response to peroxisome proliferators and fatty acids. PPARs also play an important role in the regulation of adipocyte differentiation. It is unclear however what naturally occurring compounds activate each of the PPAR subtypes. Additionally, 8(S)-HETE is able to induce differentiation of preadipocytes.

20-Hydroxyeicosatetraenoic acid
20-Hydroxyeicosatetraenoic acid (20-HETE) is a metabolite of arachidonic acid. Cytochrome P450 enzymes of the 4A and 4F families catalyze the omega-hydroxylation of arachidonic acid and produce 20-HETE. 20-HETE is a potent constrictor of renal, cerebral, and mesenteric arteries. The vasoconstrictor response to 20-HETE is associated with activation of protein kinase, Rho kinase, and the mitogen-activated protein (MAP) kinase pathway C. 20-HETE also increases intracellular Ca2+ by causing the depolarization of vascular smooth muscle membrane secondary to blocking the large-conductance Ca2+-activated K+-channels and by a direct effect on L-type Ca channels. Elevations in the production of 20-HETE mediate the myogenic response of skeletal, renal, and cerebral arteries to elevations in transmural pressure. There is an important interaction between nitric oxide (NO) and the formation of 20-HETE production. NO inhibits the formation of 20-HETE formation in renal and cerebral arteries. A fall in levels of 20-HETE contributes to the cyclic GMP-independent dilator effect of NO to activate the large-conductance Ca2+-activated K+-channels and to dilate the cerebral arteries (PMID: 16258232). Metabolite produced during NADPH dependent enzymatic oxidation of arachidonic acid. Potent vasoconstrictor [CCD]
Terfenadine
Terfenadine is only found in individuals that have used or taken this drug. In the U.S., Terfenadine was superseded by fexofenadine in the 1990s due to the risk of cardiac arrhythmia caused by QT interval prolongation.Terfenadine competes with histamine for binding at H1-receptor sites in the GI tract, uterus, large blood vessels, and bronchial muscle. This reversible binding of terfenadine to H1-receptors suppresses the formation of edema, flare, and pruritus resulting from histaminic activity. As the drug does not readily cross the blood-brain barrier, CNS depression is minimal.

Terfenadine, an H1 histamine receptor antagonist, acts as a potent apoptosis inducer in melanoma cells through modulation of Ca2+ homeostasis. Terfenadine induces ROS-dependent apoptosis, simultaneously activates Caspase-4, -2, -9[2].
Salmeterol
Salmeterol is only found in individuals that have used or taken this drug. It is a long-acting beta2-adrenergic receptor agonist drug that is currently prescribed for the treatment of asthma and chronic obstructive pulmonary disease COPD. Salmeterols long, lipophilic side chain binds to exosites near beta(2)-receptors in the lungs and on bronchiolar smooth muscle, allowing the active portion of the molecule to remain at the receptor site, continually binding and releasing. Beta(2)-receptor stimulation in the lung causes relaxation of bronchial smooth muscle, bronchodilation, and increased bronchial airflow.

Arachidonic acid
Arachidonic acid is a polyunsaturated, essential fatty acid that has a 20-carbon chain as a backbone and four cis-double bonds at the C5, C8, C11, and C14 positions. It is found in animal and human fat as well as in the liver, brain, and glandular organs, and is a constituent of animal phosphatides. It is synthesized from dietary linoleic acid. Arachidonic acid mediates inflammation and the functioning of several organs and systems either directly or upon its conversion into eicosanoids. Arachidonic acid in cell membrane phospholipids is the substrate for the synthesis of a range of biologically active compounds (eicosanoids) including prostaglandins, thromboxanes, and leukotrienes. These compounds can act as mediators in their own right and can also act as regulators of other processes, such as platelet aggregation, blood clotting, smooth muscle contraction, leukocyte chemotaxis, inflammatory cytokine production, and immune function. Arachidonic acid can be metabolized by cytochrome p450 (CYP450) enzymes into 5,6-, 8,9-, 11,12-, and 14,15-epoxyeicosatrienoic acids (EETs), their corresponding dihydroxyeicosatrienoic acids (DHETs), and 20-hydroxyeicosatetraenoic acid (20-HETE). The production of kidney CYP450 arachidonic acid metabolites is altered in diabetes, pregnancy, hepatorenal syndrome, and in various models of hypertension, and it is likely that changes in this system contribute to the abnormalities in renal function that are associated with many of these conditions. Phospholipase A2 (PLA2) catalyzes the hydrolysis of the sn-2 position of membrane glycerophospholipids to liberate arachidonic acid (PMID: 12736897, 12736897, 12700820, 12570747, 12432908). The beneficial effects of omega-3 fatty acids are believed to be due in part to selective alteration of arachidonate metabolism that involves cyclooxygenase (COX) enzymes (PMID: 23371504). 9-Oxononanoic acid (9-ONA), one of the major products of peroxidized fatty acids, was found to stimulate the activity of phospholipase A2 (PLA2), the key enzyme to initiate the arachidonate cascade and eicosanoid production (PMID: 23704812). Arachidonate lipoxygenase (ALOX) enzymes metabolize arachidonic acid to generate potent inflammatory mediators and play an important role in inflammation-associated diseases (PMID: 23404351).

Montelukast
Montelukast is a leukotriene receptor antagonist (LTRA) used for the maintenance treatment of asthma and to relieve symptoms of seasonal allergies. It is usually administered orally. Montelukast blocks the action of leukotriene D4 on the cysteinyl leukotriene receptor CysLT1 in the lungs and bronchial tubes by binding to it. This reduces the bronchoconstriction otherwise caused by the leukotriene, and results in less inflammation. Because of its method of operation, it is not useful for the treatment of acute asthma attacks. Again because of its very specific locus of operation, it does not interact with other allergy medications such as theophylline. Montelukast is marketed in United States and many other countries by Merck & Co. with the brand name Singulair. It is available as oral tablets, chewable tablets, and oral granules. In India and other countries, it is also marketed under the brand name Montair®, produced by Indian company Cipla.

Dihomo-alpha-linolenic acid
Dihomolinolenic acid, also known as 11,14,17-eicosatrienoic acid or (11z,14z,17z)-eicosa-11,14,17-trienoic acid, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, dihomolinolenic acid is considered to be a fatty acid lipid molecule. Dihomolinolenic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Dihomolinolenic acid can be found in evening primrose, which makes dihomolinolenic acid a potential biomarker for the consumption of this food product. Dihomolinolenic acid can be found primarily in blood and feces. Dihomo-alpha-linolenic acid, also known as 11,14,17-eicosatrienoic acid, is a rare polyunsaturated fatty acid of the omega-3 series. In normal humans, it represents less than 0.25\\% of serum phospholipid fatty acids. However, it is one of the most active essential fatty acids when assayed for the inhibition of fatty acid elongation/desaturation reactions which convert dietary C-18 fatty acids to C-20 eicosanoid precursors.

12-Hydroxyeicosatetraenoic acid (CAS: 71030-37-0), also known as 12-HETE, is an eicosanoid, a 5-lipoxygenase metabolite of arachidonic acid. 5-Lipoxygenase (LO)-derived leukotrienes are involved in inflammatory glomerular injury. LO product 12-HETE is associated with the pathogenesis of hypertension and may mediate angiotensin II and TGFbeta induced mesangial cell abnormality in diabetic nephropathy. 12-HETE is markedly elevated in the psoriatic lesions. 12-HETE is a vasoconstrictor eicosanoid that contributes to high blood pressure in (renovascular) hypertension and pregnancy-induced hypertension. A significant percentage of patients suffering from a selective increase in plasma LDL cholesterol (type IIa hyperlipoproteinemia) exhibits increased platelet reactivity. This includes enhanced platelet responsiveness against a variety of platelet-stimulating agents ex vivo and enhanced arachidonic acid metabolism associated with increased generation of arachidonic acid metabolites such as 12-HETE, and secretion of platelet-storage products (PMID: 7562532, 12480795, 17361113, 8498970, 1333255, 2119633). 12-HETE is a highly selective ligand used to label mu-opioid receptors in both membranes and tissue sections. The 12-S-HETE analog has been reported to augment tumour cell metastatic potential through activation of protein kinase C. 12-HETE has a diversity of biological actions and is generated by a number of tissues including the renal glomerulus and the vasculature. 12-HETE is one of the six monohydroxy fatty acids produced by the non-enzymatic oxidation of arachidonic acid. 12-HETE is a neuromodulator that is synthesized during ischemia. Its neuronal effects include attenuation of calcium influx and glutamate release as well as inhibition of AMPA receptor (AMPA-R) activation. 12-HETE is found to be associated with peroxisomal biogenesis defect and Zellweger syndrome, which are inborn errors of metabolism.

13-Hydroxyoctadecadienoic acid (13-HODE) (CAS: 18104-45-5), also known as 13(S)-hydroxy-9Z,11E-octadecadienoic acid or 13(S)-HODE, is the major lipoxygenation product synthesized in the body from linoleic acid. 13-HODE prevents cell adhesion to endothelial cells and can inhibit cancer metastasis. 13-HODE synthesis is enhanced by cyclic AMP. gamma-Linolenic acid, a desaturated metabolite of linoleic acid, causes substantial stimulation of 13-HODE synthesis. A fall in gamma-linolenic acid synthesis with age may be related to the age-related fall in 13-HODE formation (PMID: 9561154). 13-HODE is considered an intermediate in linoleic acid metabolism. It is generated from 13(S)-HPODE via the enzyme lipoxygenase (EC 1.13.11.12). 13-HODE has been shown to be involved in cell proliferation and differentiation in a number of systems. 13-HODE is found to be produced by prostate tumours and cell lines and researchers believe that there is a link between linoleic acid metabolism and the development or progression of prostate cancer (PMID: 9367845).
15-HETE
15-HETE is a hydroxyeicosatetraenoic acid. Hydroxyeicosatetraenoic acids (HETEs) are formed by the 5-, 12-, and 15-lipoxygenase (LO) pathways. The 5- and 12-LO products are mainly proinflammatory in the skin whereas the main 15-LO product 15-HETE has antiinflammatory capacities. In vitro, 15-HETE has been shown to inhibit LTB4 formation, 12-HETE formation, and specifically inhibits the neutrophil chemotactic effect of LTB4. The inhibition of LTB4 formation is probably due to modulation of the 5-LO because no changes in PGE2 formation have been determined. In vivo, 15-HETE inhibits LTB4-induced erythema and edema, and reduces LTB4 in the synovial fluid of carragheenan-induced experimental arthritis in dogs. 15-HETE also has some immunomodulatory effects. It inhibits the mixed lymphocyte reaction, induces generation of murine cytotoxic suppressor T cells, and it decreases interferon production by murine lymphoma cells. Furthermore, IL-4 and IL-13 have recently been shown to be potent activators of the 15-LO in mononuclear cells (PMID: 11104340). 15(S)-HETE is found to be associated with Zellweger syndrome, which is an inborn error of metabolism. 15(S)-HETE is a hydroxyeicosatetraenoic acid.

Leukotriene C4
Leukotriene C4 (LTC4) is a cysteinyl leukotriene (CysLT), a family of potent inflammatory mediators. Eosinophils, one of the principal cell types recruited to and activated at sites of allergic inflammation, is capable of elaborating lipid mediators, including leukotrienes derived from the oxidative metabolism of arachidonic acid (AA). Potentially activated eosinophils may elaborate greater quantities of LTC4, than normal eosinophils. These activated eosinophils thus are primed for enhanced LTC4 generation in response to subsequent stimuli. Some recognized priming stimuli are chemoattractants (e.g. eotaxin, PAF) that may participate in the recruitment of eosinophils to sites of allergic inflammation. The mechanisms by which chemoattractants and other activating cytokines (e.g. interleukin (IL)-5) or extracellular matrix components (e.g. fibronectin) enhance eosinophil eicosanoid formation are pertinent to the functions of these eicosanoids as paracrine mediators of allergic inflammation. Some eosinophil-derived eicosanoids may be active in down-regulating inflammation. It is increasingly likely that eicosanoids synthesized within cells, including eosinophils, may have intracellular (e.g. intracrine) roles in regulating cell functions, in addition to the more recognized activities of eicosanoids as paracrine mediators of inflammation. Acting extracellularly, the cysteinyl leukotrienes (CysLTs) LTC4 and its extracellular derivatives, LTD4 and LTE4 are key paracrine mediators pertinent to asthma and allergic diseases. Based on their receptor-mediated capabilities, they can elicit bronchoconstriction, mucus hypersecretion, bronchial hyperresponsiveness, increased microvascular permeability, and additional eosinophil infiltration. Eosinophils are a major source of CysLTs and have been identified as the principal LTC4 synthase expressing cells in bronchial mucosal biopsies of asthmatic subjects (PMID: 12895596). Leukotrienes 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. Leukotriene c4, also known as ltc4 or 5s,6r-ltc(sub 4), is a member of the class of compounds known as oligopeptides. Oligopeptides are organic compounds containing a sequence of between three and ten alpha-amino acids joined by peptide bonds. Thus, leukotriene c4 is considered to be an eicosanoid lipid molecule. Leukotriene c4 is practically insoluble (in water) and a moderately acidic compound (based on its pKa). Leukotriene c4 can be synthesized from icosa-7,9,11,14-tetraenoic acid. Leukotriene c4 is also a parent compound for other transformation products, including but not limited to, leukotriene C4 methyl ester, 11,12-dihydro-(12R)-hydroxyleukotriene C4, and 11,12-dihydro-12-oxoleukotriene C4. Leukotriene c4 can be found in a number of food items such as gram bean, maitake, caraway, and burbot, which makes leukotriene c4 a potential biomarker for the consumption of these food products. Leukotriene c4 can be found primarily in blood and cerebrospinal fluid (CSF), as well as throughout most human tissues. In humans, leukotriene c4 is involved in several metabolic pathways, some of which include trisalicylate-choline action pathway, antipyrine action pathway, nepafenac action pathway, and fenoprofen action pathway. Leukotriene c4 is also involved in a couple of metabolic disorders, which include leukotriene C4 synthesis deficiency and tiaprofenic acid action pathway. Moreover, leukotriene c4 is found to be associated with eczema. Leukotriene C4 (LTC4) is a leukotriene. LTC4 has been extensively studied in the context of allergy and asthma. In cells of myeloid origin such as mast cells, its biosynthesis is orchestrated by translocation to the nuclear envelope along with co-localization of cytosolic phospholipase A2 (cPLA2), Arachidonate 5-lipoxygenase (5-LO), 5-lipoxygenase-activating protein (FLAP) and LTC4 synthase (LTC4S), which couples glutathione to an LTA4 intermediate.The MRP1 transporter then secretes cytosolic LTC4 and cell surface proteases further metabolize it by sequential cleavage of the γ-glutamyl and glycine residues off its glutathione segment, generating the more stable products LTD4 and LTE4. All three leukotrienes then bind at different affinities to two G-protein coupled receptors: CYSLTR1 and CYSLTR2, triggering pulmonary vasoconstriction and bronchoconstriction .
Leukotriene D4
Leukotriene D4 (LTD4) is a cysteinyl leukotriene. Cysteinyl leukotrienes (CysLTs) are a family of potent inflammatory mediators that appear to contribute to the pathophysiologic features of allergic rhinitis. LTD4 is a pro-inflammatory mediator known to mediate its effects through specific cell-surface receptors belonging to the G-protein-coupled receptor family, namely the high-affinity CysLT1 (cysteinyl leukotriene 1) receptor. LTD4 is present at high levels in many inflammatory conditions, and areas of chronic inflammation have an increased risk for subsequent cancer development. LTD4 is associated with the pathogenesis of several inflammatory disorders, such as asthma and inflammatory bowel disease. Exposure to LTD4 increases survival and proliferation in intestinal epithelial cells. CysLT1 regulator is up-regulated in colon cancer tissue and LTD4 signalling facilitates the survival of cancer cells. LTD4 could reduce apoptosis in non-transformed epithelial cells. LTD4 causes up-regulation of beta-catenin through the CysLT1 receptor, PI3K (phosphoinositide 3-kinase), and GSK-3β (glycogen synthase kinase 3β). LTD4 induces beta-catenin translocation to the nucleus and activation of TCF/LEF family of transcription factors. LTD4 causes accumulation of free beta-catenin in non-transformed intestinal epithelial cells through the CysLT1 receptor, and this accumulation is dependent upon the activation of PI3K as well as GSK-3β inactivation (PMID: 16042577, 12607939). Leukotrienes 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.

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. (PMID: 16005201, 16613568). Lipoxin A4 (LXA4) was first identified in 1984 by Serhan and colleagues as 5-lipoxygenase interaction product of activated leukocytes.

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.

Aloin
Aloin is a constituent of various Aloe species Aloin extracted from natural sources is a mixture of two diastereomers, termed aloin A (also called barbaloin) and aloin B (or isobarbaloin), which have similar chemical properties. Aloin is an anthraquinone glycoside, meaning that its anthraquinone skeleton has been modified by the addition of a sugar molecule. Anthraquinones are a common family of naturally occurring yellow, orange, and red pigments of which many have cathartic properties, attributes shared by aloin. Aloin is related to aloe emodin, which lacks a sugar group but shares aloins biological properties. Aloin, also known as Barbaloin [Reynolds, Aloes - The genus Aloe, 2004], is a bitter, yellow-brown colored compound noted in the exudate of at least 68 Aloe species at levels from 0.1 to 6.6\\\\\% of leaf dry weight (making between 3\\\\\% and 35\\\\\% of the toal exudate) (Groom & Reynolds, 1987), and in another 17 species at indeterminate levels [Reynolds, 1995b]. It is used as a stimulant-laxative, treating constipation by inducing bowel movements. The compound is present in what is commonly referred to as the aloe latex that exudes from cells adjacent to the vascular bundles, found under the rind of the leaf and in between it and the gel. When dried, it has been used as a bittering agent in commerce (alcoholic beverages) [21 CFR 172.510. Scientific names given include Aloe perryi, A. barbadensis (= A. vera), A. ferox, and hybrids of A. ferox with A. africana and A. spicata.]. Aloe is listed in federal regulations as a natural substance that may be safely used in food when used in the minimum quantity required to produce their intended physical or technical effect and in accordance with all the principles of good manufacturing practice. This food application is generally limited to use in quite small quantities as a flavoring in alcoholic beverages and may usually be identified only as a natural flavor. ; In May 2002, the U.S. Aloin is a food and Drug Administration (FDA) issued a ruling that aloe laxatives are no longer generally recognized as safe (GRAS) and effective, meaning that aloin-containing products are no longer available in over-the-counter drug products in the United States. Aloe vera leaf latex is a concentrate of an herb or other botanical, and so meets the statutory description of an ingredient that may be used in dietary supplements Aloin A is a natural product found in Aloe arborescens with data available.

Masoprocol
Masoprocol is the meso-form of nordihydroguaiaretic acid. An antioxidant found in the creosote bush, Larrea divaricata, it is a potent lipoxygenase inhibitor that interferes with arachidonic acid metabolism. It also inhibits (though to a lesser extent) formyltetrahydrofolate synthetase, carboxylesterase, and cyclooxygenase. It has a role as an antineoplastic agent, a lipoxygenase inhibitor, a hypoglycemic agent and a metabolite. Masoprocol is a natural product found in Larrea divaricata, Schisandra chinensis, and Larrea tridentata with data available. Masoprocol is a naturally occurring antioxidant dicatechol originally derived from the creosote bush Larrea divaricatta with antipromoter, anti-inflammatory, and antineoplastic activities. Masoprocol directly inhibits activation of two receptor tyrosine kinases (RTKs), the insulin-like growth factor receptor (IGF-1R) and the c-erbB2/HER2/neu receptor, resulting in decreased proliferation of susceptible tumor cell populations. This agent may induce apoptosis in susceptible tumor cell populations as a result of disruption of the actin cytoskeleton in association with the activation of stress activated protein kinases (SAPKs). In addition, masoprocol inhibits arachidonic acid 5-lipoxygenase (5LOX), resulting in diminished synthesis of inflammatory mediators such as prostaglandins and leukotrienes. It may prevent leukocyte infiltration into tissues and the release of reactive oxygen species. A potent lipoxygenase inhibitor that interferes with arachidonic acid metabolism. The compound also inhibits formyltetrahydrofolate synthetase, carboxylesterase, and cyclooxygenase to a lesser extent. It also serves as an antioxidant in fats and oils.

Resolvin D1
Resolvin D1 (RvD1) is an autacoid resolvin. Autacoids are chemical mediators including the families of resolvins and protectins, defined by their potent bioactions and novel chemical structures. The bioactive local mediators, or autacoids, that require enzymatic generation from the omega-3 essential fatty acid EPA were first identified in resolving inflammatory exudates in vivo and carry potent stereoselective biological actions. Resolvins of the E (RvE) series are derived from eicosapentaenoic acid (EPA). Those derived from docosahexaenoic acid (DHA) were termed resolvins of the D series, for example resolvin D1 (RvD1).Resolvins and protectins have specific stereoselective actions which evoke biological actions in the nanogram range in vivo and are natural exudate products. Resolvins and protectins as distinct chemical families join the lipoxins as potent agonists of endogenous anti-inflammation and are proresolving chemical mediators of interest in human disease as potential new approaches to treatment. The term resolvins (resolution-phase interaction products) was first introduced to signify that these new structures were endogenous mediators, biosynthesized in the resolution phase of inflammatory exudates, possessing very potent anti-inflammatory and immunoregulatory actions. These actions include reducing neutrophil traffic, regulating cytokine and reactive oxygen species, and lowering the magnitude of the response. In recent years, investigators have recognized inflammation as playing a key role in many prevalent diseases not previously considered to be of inflammatory etiology. These include Alzheimers disease, cardiovascular disease, and cancer, which now join those well-appreciated inflammatory disorders such as arthritis and periodontal disease. Identifying the molecular mechanism(s) that underlie the many reports of the benefits of dietary omega-3 PUFAs remains an important challenge for nutrition and medicine. Thus, that these new mediator families, resolvins and protectins, are biosynthesized from EPA and DHA, act locally, and possess potent, novel bioactions is of interest to researchers.

11,12-DiHETrE
11,12-DiHETrE is a Cytochrome P450 (P450) eicosanoid. Arachidonic acid may be oxygenated by cytochrome P450 in several ways. Epoxidation of the double bonds leads to the regio- and enantioselective formation of four epoxyeicosatrienoic acids (EETs), which are hydrolyzed by epoxide hydrolase to vicinal diols (DHETs). 11,12-DiHETrE excretion is increased in healthy pregnant women compared with nonpregnant female volunteers, and increased even further in patients with pregnancy-induced hypertension (PIH). The physiological significance of arachidonic acid epoxides has been debated and it is unknown whether they play a role in pregnancy and parturition. Vasodilative effects, inhibition of cyclooxygenase, or inhibition of platelet aggregation by EETs have been observed only at micromolar concentrations. On the other hand, effects on the stimulus-secretion coupling during hormone release have been found in the nanomolar and picomolar range.

8,9-Epoxyeicosatrienoic acid
8,9-Epoxyeicosatrienoic acid is an epoxyeicosatrienoic acid eicosanoid, a metabolite of arachidonic acid. The P450 epoxyeicosatrienoic acids (EETs) are endogenous lipid mediators produced by P450 epoxygenases and metabolized through multiple pathways including soluble epoxide hydrolase (sEH). The cytochrome P-450 (P450) monooxygenase pathway includes enzymes of the CYP1A, CYP2B, CYP2C, CYP2E, and CYP2J subfamilies that catalyze the formation of four regioisomeric products, 5,6-, 8,9-, 11,12-, and 14,15-epoxyeicosatrienoic acid. EETs are produced in brain and perform important biological functions, including protection from ischemic injury. Both light flashes and direct glial stimulation produce vasodilatation mediated by EETs. EETs may be involved in the development of hypertension and endothelial dysfunction in DOCA-salt rats, but not in excessive collagen deposition or electrophysiological abnormalities. EETs have vasodilator and natriuretic effect. Blockade of EET formation is associated with salt-sensitive hypertension. Four regioisomeric cis-EET are primary products of arachidonic acid metabolism by cytochrome P450 epoxygenases. Upon hydration by soluble epoxide hydrolase (sEH), EET are metabolized to dihydroxyeicosatrienoic acids (DHET). These hydration products are more stable and less biologically active than EETs.

14,15-DiHETrE
14,15-DiHETrE is a Cytochrome P450 (P450) eicosanoid. Eicosanoids generated from arachidonic acid metabolism by cytochrome P450 (P450) enzymes are important autocrine and paracrine factors that have diverse biological functions. P450 eicosanoids are involved in the regulation of vascular tone, renal tubular transport, cardiac contractility, cellular proliferation, and inflammation. Regulation of P450 eicosanoid levels is determined by many factors, including the induction or repression of the P450 enzymes responsible for their formation. Fibrate drugs are part of a diverse group of compounds known as peroxisome proliferators, which also include herbicides and phthalate ester plasticizers. Peroxisome proliferators act via peroxisome proliferator-activated receptor (PPAR ). This receptor is a member of the PPAR nuclear receptor family that also consists of the PPAR and PPAR isoforms.

Leukotriene A4
Leukotriene A4 (LTA4) is the first metabolite in the series of reactions leading to the synthesis of all leukotrienes. 5-Lipoxygenase (5-LO) catalyzes the two-step conversion of arachidonic acid to LTA4.The first step consists of the oxidation of arachidonic acid to the unstable intermediate 5-hydroperoxyeicosatetraenoic acid (5-HPETE), and the second step is the dehydration of 5-HPETE to form LTA4. Leukotriene A4, an unstable epoxide, is hydrolyzed to leukotriene B4 or conjugated with glutathione to yield leukotriene C4 and its metabolites, leukotriene D4 and leukotriene E4. The leukotrienes participate in host defense reactions and pathophysiological conditions such as immediate hypersensitivity and inflammation. Recent studies also suggest a neuroendocrine role for leukotriene C4 in luteinizing hormone secretion. (PMID: 10591081, 2820055). Leukotrienes 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.

Presqualene diphosphate
Presqualene diphosphate is an intermediate in the biosynthesis of Terpenoid. It is a substrate for Farnesyl-diphosphate farnesyltransferase. [HMDB]. Presqualene diphosphate is found in many foods, some of which are soft-necked garlic, pomes, roman camomile, and white cabbage. Presqualene diphosphate is an intermediate in the biosynthesis of Terpenoid. It is a substrate for Farnesyl-diphosphate farnesyltransferase.
20-Carboxy-leukotriene B4
20-Carboxyleukotriene B4 is an omega-oxidized metabolite of leukotriene B4 (LTB4). Neutrophil microsomes are known to oxidize 20-hydroxy-LTB4 (20-OH-LTB4) to its 20-oxo and 20-carboxy derivatives in the presence of NADPH. This activity has been ascribed to LTB4 omega-hydroxylase (cytochrome P-450LTB omega). Leukotriene B4 release from polymorphonuclear granulocytes of severely burned patients was reduced as compared to healthy donor cells. This decrease is due to an enhanced conversion of LTB4 into the 20-hydroxy- and 20-carboxy-metabolites and further to a decreased LTB4-synthesis. LTB4 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.

Leukotriene E4
Leukotriene E4 (LTE4) is a cysteinyl leukotriene. Cysteinyl leukotrienes (CysLTs) are a family of potent inflammatory mediators that appear to contribute to the pathophysiologic features of allergic rhinitis. Nasal blockage induced by CysLTs is mainly due to dilatation of nasal blood vessels, which can be induced by the nitric oxide produced through CysLT1 receptor activation. LTE4 activates contractile and inflammatory processes via specific interaction with putative seven transmembrane-spanning receptors that couple to G proteins and subsequent intracellular signaling pathways. LTE4 is metabolized from leukotriene C4 in a reaction catalyzed by gamma-glutamyl transpeptidase and a particulate dipeptidase from kidney (PMID: 12607939, 12432945, 6311078).

Leukotriene B4
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 omega-oxidation carried out by specific cytochrome P450s (CYP4F) followed by beta-oxidation from the omega-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 in 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 omega-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. The term leukotriene was coined to indicate the presence of three conjugated double bonds within the 20-carbon structure of arachidonic acid as well as the fact that these compounds were derived from leucocytes such as PMNNs or transformed mast cells. Interestingly, most of the cells known to express 5-LO are of myeloid origin, which includes neutrophils, eosinophils, mast cells, macrophages, basophils, and monocytes. Leukotriene biosynthesis begins with the specific oxidation of arachidonic acid by a free radical mechanism as a consequence of interaction with 5-LO. The first enzymatic step involves the abstraction of a hydrogen atom from C-7 of arachidonate followed by the addition of molecular oxygen to form 5-HpETE (5-hydroperoxyeicosatetraenoic acid). A second enzymatic step is also catalyzed by 5-LO and involves removal of a hydrogen atom from C-10, resulting in the formation of the conjugated triene epoxide LTA4. LTA4 must then be released by 5-LO and encounter either LTA4-H (LTA4 hydrolase) or LTC4-S [LTC4 (leukotriene C4) synthase]. LTA4-H can stereospecifically add water to C-12 while retaining a specific double-bond geometry, leading to LTB4 [leukotriene B4, 5(S),12(R)-dihydroxy-6,8,10,14-(Z,E,E,Z)-eicosatetraenoic acid]. If LTA4 encounters LTC4-S, then the reactive epoxide is opened at C-6 by the thiol anion of glutathione to form the product LTC4 [5(S)-hydroxy-6(R)-S-glutathyionyl-7,9,11,14- (E,E,Z,Z)-eicosatetraenoic acid], essentially a glutathionyl adduct of oxidized arachidonic acid. Both of these terminal leukotrienes are biologically active in that specific GPCRs recognize these chemical structures and receptor recognition initiates complex intracellular signalling cascades. In order for these molecules to serve as lipid mediators, however, they must be released from the biosynthetic cell into the extracellular milieu so that they can encounter the corresponding GPCRs. Surprising features of this cascade include the recognition of the assembly of critical enzymes at the perinuclear region of the cell and even localization of 5-LO within the nucleus of some cells. Under some situations, the budding phagosome has been found to assemble these proteins. Non-enzymatic proteins such as FLAP are now known as critical partners of this protein-machine assembly. An unexpected pathway of leukotriene biosynthesis involves the transfer of the chemically reactive intermediate, LTA4, from the biosynthetic cell followed by conversion into LTB4 or LTC4 by other cells that do not express ...
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.

(PMID: 12709426, 9799565, 11408337, 17623009). Leukotrienes 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. 20-hydroxy- Leukotriene B4 (20-OH-LTB4) is an omega-hydroxylated metabolite of leukotriene B4 in human neutrophils.
