    Despite their clinical importance, saving numerous human lifes, over- and mis-uses of antibiotics have created a strong selective pressure on bacteria, which induces the emergence of (multi)resistant strains. Antibioresistance is becoming so pregnant that since 2017, WHO lists bacteria threatening most human health (AWaRe, ESKAPE lists), and those for which new antibiotics are urgently needed. Since the century turn, this context is leading to a burst in the chemical synthesis of new antibiotics, mostly derived from natural antibiotics. Among them, aminoglycosides, and especially the neomycin family, exhibit broad spectrum of activity and remain clinically useful drugs. Therefore, numerous endeavours have been undertaken to modify aminoglycosides with the aim of overcoming bacterial resistances. After having replaced antibiotic discovery into an historical perspective, briefly surveyed the aminoglycoside mode of action and the associated resistance mechanisms, this review emphasized the chemical syntheses performed on the neomycin family and the corresponding structure activity relationships in order to reveal the really efficient modifications able to convert neomycin and its analogues into future drugs. This review would help researchers to strategically design novel aminoglycoside derivatives for the development of clinically viable drug candidates. Copyright © 2022 Elsevier Inc.
