Sammendrag
Infections caused by bacteria are the third leading cause of death worldwide. Antimicrobials are used to treat and prevent those infections and enabled the development of the modern healthcare system as we know it. However, those achievements are threatened by the global emergence of antimicrobial-resistant bacteria. There is an obvious need for developing new antimicrobials. Natural environments, like the Arctic Ocean, offer largely underexplored biodiversity with promising natural antimicrobial products. This thesis investigates marine and marine-inspired molecules for their antibacterial properties and potential applications.
