  • Title: Cytochrome P450/NADPH-dependent formation of trans epoxides from trans-arachidonic acids.
    Author: Roy U, Loreau O, Balazy M.
    Journal: Bioorg Med Chem Lett; 2004 Feb 23; 14(4):1019-22. PubMed ID: 15013014.
    Abstract:
    Trans-arachidonic acids (trans-AA) are products of cis-trans isomerization of arachidonic acid by nitrogen dioxide radical (NO(2)), and occur in vivo, but their metabolism is unknown. We found that hepatic microsomes oxidized trans-AA via cytochrome P450/NADPH system to epoxides, which were hydrolyzed by epoxide hydrolase to diols (DiHETEs). 14,15-trans-AA produced one erythro diol and three threo diols each having one trans double bond.
