RESUMEN
The solid- and solution-phase synthesis of amphiphilic aminoglycoside-peptide triazole conjugates (APTCs) accessed by copper(I)-catalyzed 1,3-dipolar cycloaddition reaction between a hydrophobic and ultrashort peptide-based alkyne and a neomycin B- or kanamycin A-derived azide is presented. Antibacterial evaluation demonstrates that the antibacterial potency is affected by the nature of the peptide component. Several APTCs exhibit superior activity against neomycin B- and kanamycin A-resistant strains when compared to their parent aminoglycoside while displaying reduced activity against neomycin B- and kanamycin A-susceptible strains.
