: The ever-faster rise of antimicrobial resistance (AMR) represents a major global Public Health challenge. New chemical entities with innovative Modes of Action (MoAs) are thus desirable. We recently reported the development of a novel class of broad-spectrum bactericidal agents, the AlkylGuanidino Ureas (AGU). Due to their polycationic structure, they likely target bacterial membranes. In order to better understand their MoA, we synthesized a library of AGU derivatives by structural simplification of selected hit compounds and developed specific assays based on membrane models by means of both analytical and computational techniques. Cell-based assays provided experimental evidence that AGUs disrupt bacterial membranes without showing hemolytic behavior. Hence, we herein report a thorough chemical and biological characterization of a new series of AGUs obtained through molecular simplification, allowing the rational design of potent antibacterial compounds active on antibiotic-resistant strains.
