Here we present a proof-of-concept study, combining two known antimicrobial agents into a hybrid
structure in order to develop an emergent cationic detergent-like interaction with the bacterial membrane.
Six amphiphilic conjugates were prepared by copper (I)-catalyzed 1,3-dipolar cycloaddition
between a neomycin B-derived azide and three alkyne-modified phenolic disinfectants. Three conjugates
displayed good activity against a variety of clinically relevant Gram positive and Gram negative bacteria,
including MRSA, without the high level of hemolysis or strong binding to serum proteins commonly
observed with other cationic antimicrobial peptides and detergents.
