Structural hybridization of three aminoglycoside antibiotics yields a potent broad-spectrum bactericide that eludes bacterial resistance enzymes

Vast numbers of prevalent aminoglycoside-modifying enzymes undermine the clinical use of aminoglycoside antibiotics. We present the design and synthesis of a potent broad-spectrum bactericidal aminoglycoside based on available X-ray co-crystal structures within the ribosomal binding-site. The resulting antibiotic displays broad protection of its functional groups from inactivation by clinically relevant resistance enzymes.
