    Synthesis of Fatty Acid Amides of Catechol Metabolites that Exhibit Antiobesity Properties

    CHEMMEDCHEM, Issue 10 2010
    Bruno Almeida
    Abstract A series of fatty acid amides of 3,4-methylenedioxymethamphetamine (MDMA) catechol metabolites were synthesized in order to evaluate their biological activities. Upon administration, all synthesized compounds resulted in negative modulation of food intake in rats. The most active compounds have affinity for the CB1 receptor and/or PPAR- ,; part of their biological activity may be caused by these double interactions. [source]


    Identification of an unusual naturally occurring apolar fatty acid amide in mammalian brain and a method for its quantitative determination

    RAPID COMMUNICATIONS IN MASS SPECTROMETRY, Issue 3 2006
    Maurizio Dalle Carbonare
    Fatty acid amides (FAAs), such as the N -acylamides, N -acylethanolamides, N -acyldopamines and N -acylamino acids, are now emerging as an important new class of lipid-signalling molecules. This paper provides evidence, based on high-performance liquid chromatography/electrospray ionisation mass spectrometry (HPLC/ESI-MS/MS), gas chromatography/mass spectrometry (GC/MS) and 1H-NMR, of the occurrence in mouse and bovine brain extracts of a compound characterised by a mass spectrum attributable to a FAA not previously described, namely, the isopropyl-amide of stearic acid (SIPA). A highly sensitive GC/MS method was developed for quantification of naturally occurring SIPA and, also, for purposes of comparison, that of palmitoylethanolamide (PEA), a structurally related compound commonly determined in animal tissues. The results obtained show that SIPA levels in mouse brain are 8,10-fold higher than those of PEA. Moreover, SIPA was found in human neuroblastoma cell (SHSY-5Y) extracts, at significantly higher levels following exposure of the cells to the mitochondrial inhibitor rotenone. All this evidence not only shows surprisingly that SIPA may be found naturally in mammalian biological extracts despite the unusual functional group (i.e. isopropylamide) implicated, but also raises many important questions concerning its biological origin.

    Oleamide is a selective endogenous agonist of rat and human CB1 cannabinoid receptors

    BRITISH JOURNAL OF PHARMACOLOGY, Issue 2 2004
    James D Leggett
    The ability of the endogenous fatty acid amide, cis -oleamide (ODA), to bind to and activate cannabinoid CB1 and CB2 receptors was investigated. ODA competitively inhibited binding of the nonselective cannabinoid agonist [3H]CP55,940 and the selective CB1 antagonist [3H]SR141716A to rat whole-brain membranes with Ki values of 1.14 ,M (0.52,2.53 ,M, Hill slope=0.80, n=6) and 2.63 ,M (0.62,11.20 ,M, Hill slope=0.92, n=4), respectively. AEA inhibited [3H]CP55,940 binding in rat whole-brain membranes with a Ki of 428 nM (346,510 nM, Hill slope=,1.33, n=3). ODA competitively inhibited [3H]CP55,940 binding in human CB1 (hCB1) cell membranes with a Ki value of 8.13 ,M (4.97,13.32 ,M, n=2). In human CB2 transfected (hCB2) HEK-293T cell membranes, 100 ,M ODA produced only a partial (42.5±7%) inhibition of [3H]CP55,940 binding. ODA stimulated [35S]GTP,S binding in a concentration-dependent manner (EC50=1.64 ,M (0.29,9.32 ,M), R2=0.99, n=4,9), with maximal stimulation of 188±9% of basal at 100 ,M. AEA stimulated [35S]GTP,S binding with an EC50 of 10.43 ,M (4.45,24.42 ,M, R2=1.00, n=3, 195±4% of basal at 300 ,M). Trans -oleamide (trans- ODA) failed to significantly stimulate [35S]GTP,S binding at concentrations up to 100 ,M. ODA (10 ,M)-stimulated [35S]GTP,S binding was reversed by the selective CB1 antagonist SR141716A (IC50=2.11 nM (0.32,13.77 nM), R2=1.00, n=6). The anatomical distribution of ODA-stimulated [35S]GTP,S binding in rat brain sections was indistinguishable from that of HU210. Increases of similar magnitude were observed due to both agonists in the striatum, cortex, hippocampus and cerebellum. ODA (10 ,M) significantly inhibited forskolin-stimulated cyclic AMP (cAMP) accumulation in mouse neuroblastoma N1E 115 cells (P=0.02, n=11). ODA-mediated inhibition was completely reversed by 1 ,M SR141716A (P<0.001, n=11) and was also reversed by pretreatment with 300 ng ml,1 pertussis toxin (P<0.001, n=6). These data demonstrate that ODA is a full cannabinoid CB1 receptor agonist. Therefore, in addition to allosteric modulation of other receptors and possible entourage effects due to fatty acid amide hydrolase inhibition, the effects of ODA may be mediated directly via the CB1 receptor.

    Biosynthesis of fatty acid amide elicitors of plant volatiles by insect herbivores ,

    ARCHIVES OF INSECT BIOCHEMISTRY AND PHYSIOLOGY (ELECTRONIC), Issue 2 2005
    James H. Tumlinson
    Larvae of several species of Lepidoptera produce fatty acid amide elicitors that induce the plants on which they feed to synthesize and release volatile organic compounds. The volatiles released by the plants act as cues that aid in host location by natural enemies of the herbivorous larvae. The elicitors are synthesized in the larvae by enzymes embedded in the membranes of the crop and anterior midgut tissues. The fatty acid precursors of the elicitors are obtained from the plants on which the caterpillars feed, while the amino acid moieties appear to be obtained from pools within the insects. The fatty acid amide elicitors are rapidly hydrolyzed in the midgut and hindgut by enzymes in the gut lumen. The role of these fatty acid amides in caterpillar metabolism is not yet understood. Arch.

    GPR119, a novel G protein-coupled receptor target for the treatment of type 2 diabetes and obesity

    BRITISH JOURNAL OF PHARMACOLOGY, Issue S1 2008
    H A Overton
    GPR119 is a G protein-coupled receptor expressed predominantly in the pancreas (,-cells) and gastrointestinal tract (enteroendocrine cells) in humans. De-orphanization of GPR119 has revealed two classes of possible endogenous ligands, viz., phospholipids and fatty acid amides. Of these, oleoylethanolamide (OEA) is one of the most active ligands tested so far. This fatty acid ethanolamide is of particular interest because of its known effects of reducing food intake and body weight gain when administered to rodents. Agonists at the GPR119 receptor cause an increase in intracellular cAMP levels via G,s coupling to adenylate cyclase. In vitro studies have indicated a role for GPR119 in the modulation of insulin release by pancreatic ,-cells and of GLP-1 secretion by gut enteroendocrine cells. The effects of GPR119 agonists in animal models of diabetes and obesity are reviewed, and the potential value of such compounds in future therapies for these conditions is discussed.
