Antibacterial Efficacies of Nanostructured Aminoglycosides

The widespread use of broad-spectrum aminoglycoside antibiotics is restricted from various clinical applications due to the emergence of bacterial resistance and the adverse effects such as ototoxicity and nephrotoxicity. The intensive applicability of nanoparticles in modern medicinal chemistry has gained the interest of researchers for modification of aminoglycosides as nanoconjugates either via covalent conjugation or physical interactions to alleviate their undesirable effects and bacterial resistance. In this context, various carbohydrates, polymers, lipids, silver, gold, and silica-attached aminoglycoside nanoparticles have been reported with improvements in physicochemical properties, bioavailability, and biocompatibility in physiological medium. Overall, this review encompassed the synthesis of nanostructured aminoglycosides and their applications in the development of new antibacterial therapeutics.
