    • Bioactivity profiling and mode of action studies of antibacterial and antibiofilm agents of marine origin 

      Rahman, Ataur (Doctoral thesis; Doktorgradsavhandling, 2024-01-26)
      <p>The emergence of drug-resistant strains and new pathogens intensifies the need for new antimicrobials. Additionally, bacterial biofilms, which contribute to persistent infections, further complicate treatment efforts. The increasing difficulty in discovering and developing new antimicrobials adds to this challenge. However, marine environments, with their vast biodiversity, offer a promising ...

    • 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 ...
