Synthesis of six epoxyketooctadecenoic acid (EKODE) isomers, their generation from nonenzymatic oxidation of linoleic acid, and their reactivity with imidazole nucleophiles.[Pubmed:17979284]
J Org Chem. 2007 Dec 7;72(25):9471-80.
As a class of linoleic acid oxidation products, epoxyketooctadecenoic acids (EKODEs), are formed in vivo and in vitro by a free radical mechanism initiated by either enzymatic or nonenzymatic pathways. They have so far been made available in small-scale quantities, often as isomeric mixtures, from reductive decomposition of linoleic acid-derived hydroperoxides. There is major interest in these compounds owing to their highly potent biological activities and their ability to covalently modify proteins. The synthesis of six EKODE regio- and stereoisomers, two trans alpha',beta'-epoxy-alpha,beta-enones, and two trans and the two cis gamma,delta,-epoxy-alpha,beta-enones was accomplished, with the key steps being Wittig-type reactions and aldol condensations. All six EKODE isomers were confirmed by HPLC to be generated in the autoxidation of linoleic acid promoted by Fe(II)/ascorbic acid through spiking in of authentic samples. On the basis of evidence for EKODE modification of protein His residues, the reactions of Nalpha-Benzoyl-L-histidine with autoxidizing linoleic acid and with the individual EKODE isomers were compared, as were the kinetics of the various EKODE reactions with imidazole nucleophiles. The structures of His-EKODE-(E)-I adducts were confirmed to reflect conjugate addition (epoxide ring remains intact) through an NMR study of the reaction of imidazole with a generic EKODE-(E)-I analog. The synthesis of the EKODE isomers makes these important molecules available for further chemical and biological evaluation.
Detoxications in peripatus. Sulphate, phosphate and histidine conjugations.[Pubmed:5472152]
Biochem J. 1970 Jun;118(1):1-8.
Phenols were detoxified in the Onycophoran Peripatoides novaezealandiae by conjugation with sulphuric acid and phosphoric acid, but no evidence for a glycoside detoxication could be found. [(14)C]Benzoic acid was metabolized in 24h to N(2)-Benzoyl-L-histidine, which was identified by electrophoresis, chromatography and dilution analysis. Similar conjugates were formed with p-aminobenzoic acid and p-nitrobenzoic acid. In longer-duration experiments further unidentified metabolites were formed, two of which appeared to result from the further metabolism of the histidine conjugate.
