    • Kinase chemodiversity from the Arctic: the breitfussins 

      Østnes Hansen, Kine; Andersen, Jeanette hammer; Bayer, Annette; Pandey, Sunil Kumar; Lorentzen, Marianne; Jørgensen, Kåre Bredeli; Sydnes, Magne Olav; Guttormsen, Yngve; Baumann, Matthias; Koch, Uwe; Klebl, Bert; Eickhoff, Jan; Haug, Bengt Erik; Isaksson, Johan; Hansen, Espen (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-24)
      In this work, we demonstrate that the indole-oxazole-pyrrole framework of the breitfussin family of natural products is a promising scaffold for kinase inhibition. Six new halogenated natural products, breitfussin C–H (3 – 8) were isolated and characterized from the Arctic, marine hydrozoan Thuiaria breitfussi. The structures of two of the new natural products were also confirmed by total synthesis. ...

    • Total synthesis of tubastrine and 3-dehydroxy tubastrine by microwave-assisted cross-coupling reactions 

      Lorentzen, Marianne; Bayer, Annette; Sydnes, Magne Olav; Jørgensen, Kåre Bredeli (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09-03)
      The first syntheses of tubastrine and 3-dehydroxy tubastrine are described. The target compounds were prepared in four consecutive steps from commercially available starting materials. The central scaffold was formed by a microwave-assisted C–N cross-coupling reaction between 1,3-bis(<i>tert</i>-butoxycarbonyl)-guanidine and (<i>E</i>)-((4-(2-iodovinyl)-1,2-phenylene)bis(oxy))bis(<i>tert</i>-butyl ...
