  • Biocatalytic regio- and stereoselective access to ω-3 endocannabinoid epoxides with peroxygenase from oat flour
    作者:Claudia Sanfilippo、Angela Patti
    DOI:10.1016/j.bioorg.2021.105014
    日期:2021.8
    ethanolamides of ω-3 fatty acids EPA and DHA, regarded as biologically active ω-3 endocannabinoids, in the presence of a peroxygenase-containing preparation from oat flour was investigated. Good regio- and steroselectivity toward the formation of the epoxide on the terminal double bond in the chain was observed with both these fatty acid derivatives and chiral monoepoxides 1 or 2 in 74% optical purity and 51–53%

  • Trans Lipid Library: Synthesis of Docosahexaenoic Acid (DHA) Monotrans Isomers and Regioisomer Identification in DHA-Containing Supplements

    benefits. The characterization of the six monotrans DHA regioisomers is an open issue to address for analytical, biological, and nutraceutical applications. Here we report the preparation, separation, and first identification of each isomer by a dual approach consisting of the following: (i) the direct thiyl radical-catalyzed isomerization of cis-DHA methyl ester and (ii) the two-step synthesis from cis-DHA

  • Stereoselective epoxidation of the last double bond of polyunsaturated fatty acids by human cytochromes P450

    Cytochromes P450 (CYPs) metabolize polyunsaturated long-chain fatty acids (PUFA-LC) to several classes of oxygenated metabolites. Through use of human recombinant CYPs, we recently showed that CYP1A1, -2C19, -2D6, -2E1, and -3A4 are mainly hydroxylases, whereas CYP1A2, -2C8, -2C9, and -2J2 are mainly epoxygenases of arachidonic acid (AA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), respectively. It is worth noting that the last double bond of these PUFAs, i.e., omega 6 in AA or omega 3 in EPA and DHA, respectively, was preferentially epoxidized. In this study, we have characterized the stereoselectivity of this epoxidation reaction by comparison with the PUFA-LC epoxide stereoisomers obtained from the enantioselective bacterial CYP102A1 F87V. The stereoselectivity of the epoxidation of the last olefin of AA (omega 6), EPA (omega 3), or DHA (omega 3) differed between the CYP isoforms but was similar for EPA and DHA. These data give additional insight into the PUFA-LC epoxide enantiomers generated by the hepatic CYPs.-Lucas, D., S. Goulitquer, J. Marienhagen, M. Fer, Y. Dreano, U. Schwaneberg, Y. Amet, and L.
