Chemical Modifications Reduce Auditory Cell Damage Induced by Aminoglycoside Antibiotics

10.1021/jacs.9b12420

This study investigated auditory cell damage induced by aminoglycoside antibiotics, aiming to reduce their ototoxicity through chemical modifications while maintaining their antibacterial efficacy. The research team focused on apramycin (APR) and geneticin (G-418), two aminoglycosides considered to be among the least and most toxic, respectively. Using molecular dynamics simulations and experiments, the researchers discovered that chemical modifications could significantly impact the influence of these antibiotics on the essential movement freedom of the ribosome's decoding site, which in turn affects their ototoxicity. The results indicated that certain chemical modifications could reduce the auditory cell damage caused by aminoglycosides without affecting their antibacterial activity, suggesting a new paradigm for the development of safer aminoglycoside antibiotics. The chemicals used in the process included APR and G-418 and their semi-synthetic derivatives, as well as various molecules and compounds employed in the simulations and testing.
