| 12-hydroxy-5,8,14-eicosatrienoic acid | | 12R-HETrE |
| 5,8,11-eicosatriynoic acid | A C20 polyunsaturated fatty acid having three triple bonds in the 5-, 8- and 11-positions. | 5,8,11-icosatriynoic acid |
| bay u9773 | A dicarboxylic acid that is that is (7E,9E,11Z,14Z)-icosa-7,9,11,14-tetraenoic acid substituted by a hydroxy group at position 4S and a (4-carboxyphenyl)sulfanediyl group at 5R. It is a dual cysteinyl leukotriene receptor antagonist that acts at the CysLT1 and CysLT2 receptors (IC50 = 0.44 and 0.30 muM, respectively). | BAYu9773 |
| decaprenoic acid | A polyunsaturated fatty acid that is octa-2,6-dienoic acid bearing two methyl substituents at positions 3 and 7 (the 2E-isomer). | geranic acid |
| leukotriene a4 | A leukotriene that is the (5S,6S)-epoxy derivative of (7E,9E,11Z,14Z)-icosa-7,9,11,14-tetraenoic acid. | leukotriene A4 |
| leukotriene b3 | | LTB3 |
| sq-23377 | A very long-chain fatty acid that is docosa-10,16-dienoic acid which is substituted by methyl groups at positions 4, 6, 8, 12, 14, 18 and 20, by hydroxy groups at positions 11, 19 and 21, and by a (2',5-dimethyloctahydro-2,2'-bifuran-5-yl)ethanol group at position 21. An ionophore produced by Streptomyces conglobatus, it is used in research to raise the intracellular level of Ca(2+) and as a research tool to understand Ca(2+) transport across biological membranes. | ionomycin |
