      Lind, Karianne Fredenfeldt; Hansen, Espen; Østerud, Bjarne; Eilertsen, Karl-Erik; Bayer, Annette; Engqvist, Stig Olov Magnus; Leszczak, Kinga; Jørgensen, Trond Ø.; Andersen, Jeanette hammer (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      In this paper, we present novel bioactivity for barettin isolated from the marine sponge Geodia barretti. We found that barettin showed strong antioxidant activity in biochemical assays as well as in a lipid peroxidation cell assay. A de-brominated synthetic analogue of barettin did not show the same activity in the antioxidant cell assay, indicating that bromine is important for cellular activity. ...

    • In vivo exposure to northern diatoms arrests sea urchin embryonic development 

      Gudimova, Elena; Eilertsen, Hans Christian; Jørgensen, Trond Ø.; Hansen, Espen (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-01)
      There are numerous reports indicating that marine diatoms may act harmful to early developmental stages of invertebrates. It is believed that the compounds responsible for these detrimental effects are oxylipins resulting from oxidized polyunsaturated fatty acids, and that they may function as grazing deterrents. Most studies reporting these effects have exposed test organisms to diatom extracts or ...
