    development, inflammation, and pathogenesis in various organisms. The regiospecificity of LOX from Myxococcus xanthus, a gram-negative bacterium, was investigated. The enzyme catalyzed oxygenation at the n-9 position in C20 and C22 polyunsaturated fatty acids (PUFAs) to form 12S- and 14S-hydroxy fatty acids (HFAs), respectively, and oxygenation at the n-6 position in C18 PUFAs to form 13-HFAs.

    The present invention relates to methods for producing fatty acid hydroperoxides. In particular, this invention relates to the production of C18 hydroperoxy polyunsaturated fatty acids, catalyzed by a specific 13-lipoxygenase (LOX) originating from a cyanobacterium. Further, the invention relates to methods of producing flavor ingredients and/or fragrance ingredients using the 13-LOX derived hydroperoxy fatty acids as starting compounds.

  • Structural requirements for the inhibition of 5-lipoxygenase by 15-hydroxyeicosa-5,8,11,13-tetraenoic acid analogs
    作者:Fortuna Haviv、James D. Ratajczyk、Robert W. DeNet、Yvonne C. Martin、Richard D. Dyer、George W. Carter
    DOI:10.1021/jm00385a005
    日期:1987.2
    The structural requirements for inhibition of RBL-1 (rat basophilic leukemia) 5-lipoxygenase by 15-hydroxyeicosa-5,8,11,13-tetraenoic acid (15-HETE, 1) were studied by systematic chemical modifications of the molecule at the hydroxyl and carboxyl groups, the double bonds, and the carboxylate and omega side chains. The most potent inhibitors were analogues that contained a 5,8-cis,cis-diene system and acted as alternate substrates for the enzyme. However, several analogues in which the 5,8-diene had been reduced were also found to inhibit the enzyme. Inhibition of 5-lipoxygenase by 15-hydroxyeicosa-11,13-dienoic acid (15-HEDE) analogues was optimal in compounds that generally contained a free carboxyl group, a carboxylate side chain of nine carbons, an omega side chain of five or six carbons, a cis,trans- or trans,cis-11,13-diene or 11,13-diyne system, and a 15-hydroxyl group. Conversion of 15-HEDE to its 16-membered lactone reduced but did not eliminate 5-lipoxygenase inhibitory activity. In contrast, a 3- to 10-fold enhancement of activity occurred when 5,15-diHETE (58) or 5-HETE (56) were cyclized to their respective delta-lactones. Molecular modeling of 15-HEDE analogues, modified in the C11-C15 region, showed that inactive analogues protrude into regions in space not occupied by active analogues. These structural studies indicate that multiple regions are important for 5-lipoxygenase inhibition by both 15-HETE and 15-HEDE analogues and that no single region plays a predominant role in inhibition.
