    • Antimicrobial activity of amphipathic α,α-disubstituted β-amino amide derivatives against ESBL–CARBA producing multi-resistant bacteria; effect of halogenation, lipophilicity and cationic character 

      Paulsen, Marianne Hagensen; Ausbacher, Dominik; Bayer, Annette; Engqvist, Magnus; Hansen, Terkel; Haug, Tor; Anderssen, Trude; Andersen, Jeanette Hammer; Sollid, Johanna U. Ericson; Strøm, Morten B. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-06)
      The rapid emergence and spread of multi-resistant bacteria have created an urgent need for new antimicrobial agents. We report here a series of amphipathic α,α-disubstituted β-amino amide derivatives with activity against 30 multi-resistant clinical isolates of Gram-positive and Gram-negative bacteria, including isolates with extended spectrum β-lactamase – carbapenemase (ESBL-CARBA) production. A ...

    • A concise SAR-analysis of antimicrobial cationic amphipathic barbiturates for an improved activity-toxicity profile 

      Langer, Manuel K; Rahman, Ataur; Dey, Hymonti; Anderssen, Trude; Zilioli, Francesco; Haug, Tor; Blencke, Hans-Matti; Stensvåg, Klara; Strøm, Morten B.; Bayer, Annette (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-05)
      An amphipathic barbiturate mimic of the marine eusynstyelamides is reported as a promising class of antimicrobial agents. We hereby report a detailed analysis of the structure-activity relationship for cationic amphipathic N,N′ -dialkylated-5,5-disubstituted barbiturates. The influence of various cationic groups, hydrocarbon linkers and lipophilic side chains on the compounds’ antimicrobial potency ...

    • Investigation of tetrasubstituted heterocycles reveals hydantoins as a promising scaffold for development of novel antimicrobials with membranolytic properties 

      Langer, Manuel K; Rahman, Ataur; Dey, Hymonti; Anderssen, Trude; Blencke, Hans-Matti; Haug, Tor; Stensvåg, Klara; Strøm, Morten B.; Bayer, Annette (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-24)
      Mimics of antimicrobial peptides (AMPs) have been proposed as a promising class of antimicrobial agents. We report the analysis of five tetrasubstituted, cationic, amphipathic heterocycles as potential AMP mimics. The analysis showed that the heterocyclic scaffold had a strong influence on the haemolytic activity of the compounds, and the hydantoin scaffold was identified as a promising template for ...

    • Novel antimicrobial peptides EeCentrocins 1, 2 and EeStrongylocin 2 from the Edible sea urchin Echinus esculentus have 6-br-trp post-translational modifications 

      Solstad, Runar Gjerp; Li, Chun; Isaksson, Johan; Johansen, Jostein a; Svenson, Johan; Stensvåg, Klara; Haug, Tor (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-03-23)
      The global problem of microbial resistance to antibiotics has resulted in an urgent need to develop new antimicrobial agents. Natural antimicrobial peptides are considered promising candidates for drug development. Echinoderms, which rely on innate immunity factors in the defence against harmful microorganisms, are sources of novel antimicrobial peptides. This study aimed to isolate and characterise ...
