Synthesis of 9-Oxononanoic Acid, a precursor for biopolymers
ChemSusChem 2013 Nov;6(11):2149-56.PMID:23934656DOI:10.1002/cssc.201300183.
Polymers based on renewable resources have become increasingly important. The natural functionalization of fats and oils enables an easy access to interesting monomeric building blocks, which in turn transform the derivative biopolymers into high-performance materials. Unfortunately, interesting building blocks of medium-chain length are difficult to obtain by traditional chemical means. Herein, a biotechnological pathway is established that could provide an environmentally suitable and sustainable alternative. A multiple enzyme two-step one-pot process efficiently catalyzed by a coupled 9S-lipoxygenase (St-LOX1, Solanum tuberosum) and 9/13-hydroperoxide lyase (Cm-9/13HPL, Cucumis melo) cascade reaction is proposed as a potential route for the conversion of linoleic acid into 9-Oxononanoic Acid, which is a precursor for biopolymers. Lipoxygenase catalyzes the insertion of oxygen into linoleic acid through a radical mechanism to give 9S-hydroperoxy-octadecadienoic acid (9S-HPODE) as a cascade intermediate, which is subsequently cleaved by the action of Cm-9/13HPL. This one-pot process afforded a yield of 73 % combined with high selectivity. The best reaction performance was achieved when lipoxygenase and hydroperoxide lyase were applied in a successive rather than a simultaneous manner. Green leaf volatiles, which are desired flavor and fragrance products, are formed as by-products in this reaction cascade. Furthermore, we have investigated the enantioselectivity of 9/13-HPLs, which exhibited a strong preference for 9S-HPODE over 9R-HPODE.
A lipid peroxidation product 9-Oxononanoic Acid induces phospholipase A2 activity and thromboxane A2 production in human blood
J Clin Biochem Nutr 2013 May;52(3):228-33.PMID:23704812DOI:10.3164/jcbn.12-110.
Lipid peroxidation products are known to cause toxicity by reacting with biologically significant proteins, but the inducing role of peroxidation products has been not noted to produce degenerative disease-related eicosanoids. Here, 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 arachidonate cascade and eicosanoid production. An exposure of fresh human blood to the atmosphere at 37°C accumulated 9-ONA, increasing peroxide value and thiobarbituric acid reactive substances in the blood. The lipid peroxidation was accompanied by significant increases of PLA2 activity and thromboxane B2 (TxB2) production, which is a stable metabolite of thromboxane A2 (TxA2) and a potent agonist of platelet aggregation. These events were abolished by standing the blood under nitrogen. The addition of organically synthesized 9-ONA resumed the activity of PLA2 and the production of TxB2. Also, 9-ONA induced platelet aggregation dose-dependently. These results indicated that 9-ONA is the primary inducer of PLA2 activity and TxA2 production, and is probably followed by the development of diseases such as thrombus formation. This is the first report to find that a lipid peroxidation product, 9-ONA, stimulates the activity of PLA2.
Effect of orally administered 9-Oxononanoic Acid on lipogenesis in rat liver
Biochim Biophys Acta 1988 Feb 4;958(2):199-204.PMID:2892534DOI:10.1016/0005-2760(88)90177-4.
9-Oxononanoic Acid, which is one of the major products of the autoxidation of linoleic acid, was administered orally to rats and its effect on hepatic lipid metabolism was investigated. The de novo synthesis of fatty acids was strongly reduced 30 h after the administration of 100 mg of 9-Oxononanoic Acid as compared to that in the saline-administered group. Activity of acetyl-CoA carboxylase decreased by 60% and the activity of carnitine palmitoyltransferase increased by 35% in the test group. The level of triacylglycerols in serum was low and the level of free fatty acids remained unchanged. Thus, the administration of 9-Oxononanoic Acid decreased hepatic lipogenesis. It is generally believed that the reduction in lipogenesis is facilitated by a decrease in the NADPH level. The ratio of NADPH/NADP in the test group, however, became high as compared to that in the control group, and the activities of glucose 6-phosphate and isocitrate dehydrogenases increased. On the other hand, the levels of CoA derivatives, especially long-chain acyl-CoA, were higher in the test group than in the control. Therefore, the reduction of hepatic lipogenesis in the 9-Oxononanoic Acid group could be attributed to the inhibition of acetyl-CoA carboxylase by the accumulated long-chain acyl-CoA.
Products and mechanisms of the reaction of oleic acid with ozone and nitrate radical
J Phys Chem A 2005 May 26;109(20):4517-30.PMID:16833788DOI:10.1021/jp0500900.
The heterogeneous reactions of deposited, millimeter-sized oleic acid droplets with ozone and nitrate radicals are studied. Attenuated total reflectance infrared spectroscopy (ATR-IR), gas chromatography-mass spectrometry (GC-MS), and liquid chromatography-mass spectrometry (LC-MS) are used for product identification and quantification. The condensed-phase products of the ozonolysis of oleic acid droplets are 1-nonanal (30 +/- 3% carbon yield), 9-Oxononanoic Acid (14 +/- 2%), nonanoic acid (7 +/- 1%), octanoic acid (1 +/- 0.2%), azelaic acid (6 +/- 3%), and unidentified products. The infrared spectra show that a major fraction of the unidentified products contain an ester group. Additionally, the mass spectra show that at least some of the unidentified products have molecular weights greater than 1000 amu, which implicates a polymerization reaction. The observed steps of 172 amu (9-Oxononanoic Acid) and 188 amu (azelaic acid Criegee intermediate) in the mass spectra suggest that these species are the monomers in the condensed-phase polymerization reactions. 9-Oxononanoic Acid is proposed to lengthen the molecular chain via secondary ozonide formation; the azelaic acid Criegee intermediate links molecules units via ester formation (specifically, alpha-acyloxyalkyl hydroperoxides). For the reaction of oleic acid with nitrate radicals, functional groups including -ONO(2), -O(2)NO(2), and -NO(2) are observed in the infrared spectra, and high molecular weight molecules are formed. Environmental scanning electron microscopy (ESEM) is employed to examine the hygroscopic properties of the oleic acid droplets before and after exposure to ozone or nitrate radical. After reaction, the droplets take up water at lower relative humidities compared to the unreacted droplets. The increased hygroscopic response may indicate that the oxidative aging of atmospheric organic aerosol particles has significant impact on radiative forcing.
Simple and economic syntheses of some (Z)-7- and (Z)-9-alkenyl acetates, and of (E,Z)-7,9-dodecadien-1-yl acetate, the sex pheromone of the European grapevine moth, using aleuritic acid as a common starting material
J Chem Ecol 1985 Jan;11(1):113-24.PMID:24311103DOI:10.1007/BF00987610.
Short syntheses of (Z)-7-dodecen-1-yl acetate, (Z)-7-tetradecen-1-yl acetate, (Z)-9-dodecen-1-yl acetate, and (Z)-9-tetradecen-1-yl acetate from 7-hydroxyheptanal and 9-Oxononanoic Acid precursors obtained by oxidative cleavage of easily available aleuritic acid are reported. The key step in these syntheses is a stereoselective Wittig reaction between aldehyde and alkyl-phosphonium salt. Wittig-Horner type reaction of 7-hydroxyheptanal and diethyl cyanomethylphosphonate gave the α,β-unsaturated nitrile derivative which after protection of the hydroxyl group was reduced to the corresponding aldehyde. Wittig reaction of the latter, followed by acetylation, completed the synthesis of (E,Z)-7,9-dodecadien-1-yl acetate, the sex pheromone of the European grapevine mothLobesia botrana Schiff.
