  • Biochemistry of the Eicosanoids: Cyclooxygenase and Lipoxygenase Products of Polyunsaturated Fatty Acids
    Lipids in Modern Nutrition, edited by M. Horisberger and U. Bracco. Nestle Nutrition, Vevey/Raven Press, New York © 1987. Biochemistry of the Eicosanoids: Cyclooxygenase and Lipoxygenase Products of Polyunsaturated Fatty Acids Elisabeth Granstrom Department of Physiological Chemistry, Karolinska Institutet, Stockholm, Sweden Certain polyunsaturated fatty acids can be metabolized by oxygenation into a large family of biologically active substances, the so-called prostanoids or eicosa- noids. This family includes the prostaglandins, thromboxanes, prostacyclins, leu- kotrienes, lipoxins, and also a number of related mono-, di-, and trihydroxy com- pounds as well as epoxygenated fatty acids. Most of these substances are potent compounds and display a wide variety of effects in many biological systems. Among these are effects on blood pressure, smooth muscle contractility, kidney function, cyclic nucleotide levels, glandular excretion, hormone secretion, platelet aggregation, vessel tone, temperature regu- lation, lipolysis, chemotaxis, immune response, cell growth and differentiation, electrolyte and water balance, etc. In combination with the fact that the eicosa- noids are almost ubiquitous in the mammalian body, it is not surprising that these substances are supposed to be involved in many physiological as well as pathologi- cal conditions in the organism. Thus, altered eicosanoid levels are sometimes found to coincide with the appearance of certain symptoms, and normalization oc- curs upon successful treatment of the condition with drugs

  • Prostanoic Acid
    Prostanoic Acid and Prostaglandins Paul May Bristol University Molecule of the Month January 2007 Also available: JSMol version. What are Prostaglandins? Prostaglandins are important biologically active molecules that resemble hormones in their effects, but are chemically quite different. They received their name because they were first detected in human seminal fluid obtained from the prostate gland. They were not detected for many years because they occur in such low concentrations and have such short half-lives. Prostaglandins are present in almost all cells and tissues, and they are one of the most potent of all biological agents. As little as a nanogram can be biologically active! Prostanoic Acid - the basic building block of the prostaglandins In the body, the prostaglandins are based upon the 20 carbon structure of prostanoic acid, which is a fatty acid containing a 5-membered cyclopentane ring. They are named as PG (for prostaglandin), followed by another letter from A-H depending upon the oxidation state and sidegroups of the cyclopentane ring. A subscript usually indicates the number of double bonds in the structure. For example, PGE2 means a carbonyl group at carbon-9 and an -OH group attached to carbon-11, with 2 double bonds in the tail groups. Prostaglandins actually belong to a larger class of compounds called eicosanoids, and a very slight change in their structure or sidegroups can completely alter their biological function. What do they do? In general, the effects of the prostaglandins are based on certain broad powers: (a) regulation of the activity of certain smooth muscles, causing them to contract or relax, (b) they induce or prevent secretions from glands, especially endocrine glands, and (c) affect blood clotting and flow.

  • The Potential Role of Prostaglandins in Skeletal and Muscular Disorders *
    ANNALS OF CLINICAL AND LABORATORY SCIENCE, Vol. 5, No. 4 Copyright © 1975, Institute for Clinical Science The Potential Role of Prostaglandins in Skeletal and Muscular Disorders * ROBERT B. ZURIER, M.D. Division of Rheumatic Diseases, Department of Medicine, University of Connecticut School of Medicine Farmington, CT 06032 ABSTRACT Musculoskeletal diseases such as rheumatoid arthritis and polymyositis are characterized by chronic inflammation. There is evidence to suggest that prosta­ glandins participate in the production of the inflammatory response. In several tissues, the production of inflammation has been associated with the release of prostaglandins. The inhibitory effect of some anti-inflammatory agents on prosta­ glandin synthesis further suggests a prostaglandin role in inflammation. Reduction by prostaglandins of release from cells of mediators of inflammation has been described. Prostaglandin treatment also suppresses acute and chronic inflam­ mation in several experimental models. Thus, prostaglandins may serve to regu­ late the inflammatory response. Introduction substances in crystalline form and described their chemical structure.3 The first clue to the existence of prosta­ glandins emerged in 1930 when two New York City gynecologists observed that Structure human myometrium exhibited rhythmic The basic structure common to all prosta­ contractions and relaxation when incubated glandins is a prostanoic acid skeleton, a 20 with fresh human semen.19 Goldblatt10 and carbon atom unsaturated hydroxy fatty acid von Euler33 independently confirmed this with a cyclopentane ring at C8-C 12 (figure finding and identified the active principle as 1).

  • Chapter 1 BASICS on LIPID CHEMISTRY
    Chapter 1 BASICS ON LIPID CHEMISTRY This chapter deals with the basics of lipid chemistry. Chemical structures, biosynthetic pathway and some properties of important lipids are explained. 1-1 Saturated fatty acid Saturated fatty acids have no double bond in the carbon chains. Naturally occurring fatty acids usually have carbons of even numbers, but the ones with odd number of carbons also exist. Acids from C2 to C30 (or longer) are known, but the most common and most important fall in the range of C12 to C22. Table 1-1-1 shows some major saturated fatty acids. Systematic Name Trivial name Chemical structure dodecanoic acid lauric acid tetradecanoic acid myristic acid hexadecanoic acid palmitic acid octadecanoic acid stearic acid eicosanoic acid arachidic acid docosanoic acid behenic acid Table 1-1-1: Saturated fatty acid. 1-2 Unsaturated fatty acid Unsaturated fatty acids are the ones with one or more double bonds. Table 1-2-2 summarizes some major unsaturated fatty acids. Usually, the double bonds are in cis or Z configuration, 1 and double bonds in di- or polyunsaturated fatty acids are interrupted by a methylene (- CH2-) group (Figure 1-2-1). Thus, generally, unsaturated fatty acids can be expressed by (i) number of carbons, (ii) number of double bonds and (iii) the position at which the first double bond from the !-position (= methyl group) appears. For example, an expression “18:2 !-6 for linoleic acid” indicates “a fatty acid with 18 carbons, with 2 double bonds starting at the 6th carbon from the methyl end”.

  • Oxylipins Derived from 20 C Fatty Acid Precursor Arachidonic Acid (AA) Is Not Sole Substrate for the Enzymes
    LIPIDS oxylipins Marek Vecka OXYLIPINS OXYLIPINS = oxygenated fatty acids biologically active as lipid mediators eicosanoids - products of transformation of FA with 20 C AA (20:4n-6), EPA (20:5n-3), DHGLA (20:3n-6) docosanoids - products of transformation of FA with 22 C DHA (22:6n-3) octadecanoids - products of transformation of FA with 18 C ALA (18:3n-3) (important to plants) OXYLIPINS OXYLIPINS = oxygenated fatty acids biologically active as lipid mediators I. production by enzymes - FA are transformed via several pathways: Cyclic structures of oxylipins 1. cyclooxygenase pathway Linear structures of oxylipins 2. lipoxygenase pathway oxidative 3. epoxygenase pathway stress II. nonenzymatic production - the reactions are catalysed by free radicals in vivo - reactions usually lack stereospecificity EICOSANOIDS Oxylipins derived from 20 C fatty acid precursor inhibited by glucocorticoids Arachidonate pathway (cascade) ↑lipocortins = inhibitors of PLA2 I. Initiation: AA release from PL by PLA2 II. Further metabolization by enzymes - prostanoids (prostaglandins (PG) + thromboxanes (Tx)) - Leukotrienes (LT) - Lipoxins (Lx) - HETEs, EETs EICOSANOIDS oxylipin pathways (cascades) prostaglandins PGD2 PGI2 PGF2a prostacyclin PGH2 PGE2 thromboxanes prostanoids TxA2 cyclooxygenase TxB2 arachidonic acid lipoxins CYP450 lipoxygenase monoxygenases leukotrienes HTES, EETs LTB4 5HpETE LTA4 LTC4 LTD4 LTE4 EICOSANOIDS mode of action – ligands of receptors prostaglandins IP DP1 EP1 EP2 thromboxanes FPA,B DP2 EP3A-D EP4 TPa TPb prostanoids cyclooxygenase
