    • Selective isolation of Arctic marine actinobacteria and a down-scaled fermentation and extraction strategy for identifying bioactive compounds 

      Schneider, Yannik Karl Heinz; Hagestad, Ole Christian; Li, Chun; Hansen, Espen Holst; Andersen, Jeanette Hammer (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-21)
      Actinobacteria are among the most prolific producers of bioactive secondary metabolites. In order to collect Arctic marine bacteria for the discovery of new bioactive metabolites, actinobacteria were selectively isolated during a research cruise in the Greenland Sea, Norwegian Sea and the Barents Sea. In the frame of the isolation campaign, it was investigated how different sample treatments, isolation ...

    • Signalling and bioactive metabolites from Streptomyces sp. RK44 

      Fang, Qing; Maglangit, Fleurdeliz; Wu, Linrui; Ebel, Rainer; Kyeremeh, Kwaku; Andersen, Jeanette Hammer; Annang, Frederick; Pérez-Moreno, Guiomar; Reyes, Fernando; Deng, Hai (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-22)
      <i>Streptomyces</i> remains one of the prolific sources of structural diversity, and a reservoir to mine for novel natural products. Continued screening for new Streptomyces strains in our laboratory led to the isolation of <i>Streptomyces</i> sp. RK44 from the underexplored areas of Kintampo waterfalls, Ghana, Africa. Preliminary screening of the metabolites from this strain resulted in the ...

    • Synthesis and Evaluation of the Tetracyclic Ring-System of Isocryptolepine and Regioiso-Mers for Antimalarial, Antiproliferative and Antimicrobial Activities 

      Håheim, Katja Stangeland; Lindback, Emil; Tan, Kah Ni; Albrigtsen, Marte; Helgeland, Ida Therese Urdal; Clemence, Lauga; Matringe, Theodora; Kennedy, Emily K.; Andersen, Jeanette Hammer; Avery, Vicky M.; Sydnes, Magne Olav (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-30)
      A series of novel quinoline-based tetracyclic ring-systems were synthesized and evaluated in vitro for their antiplasmodial, antiproliferative and antimicrobial activities. The novel hydroiodide salts 10 and 21 showed the most promising antiplasmodial inhibition, with compound 10 displaying higher selectivity than the employed standards. The antiproliferative assay revealed novel pyridophenanthridine ...

    • Two Novel Lyso-Ornithine Lipids Isolated from an Arctic Marine Lacinutrix sp. Bacterium 

      Kristoffersen, Venke; Jenssen, Marte; Raid Jawad, Heba; Isaksson, Johan; Hansen, Espen; Rämä, Teppo; Østnes Hansen, Kine; Andersen, Jeanette Hammer (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-31)
      The Lacinutrix genus was discovered in 2005 and includes 12 Gram-negative bacterial species. To the best of our knowledge, the secondary metabolite production potential of this genus has not been explored before, and examination of Lacinutrix species may reveal novel chemistry. As part of a screening project of Arctic marine bacteria, the Lacinutrix sp. strain M09B143 was cultivated, extracted, ...
