Aminoglycoside antibiotics are protein synthesis inhibitors applied to treat infections caused mainly by aerobic Gram-negative bacteria. Due to their adverse side effects they are last resort antibiotics typically used to combat pathogens resistant to other drugs. Aminoglycosides target ribosomes. We describe the interactions of aminoglycoside antibiotics containing a 2-deoxystreptamine (2-DOS) ring with 16S rRNA. We review the computational studies, with a focus on molecular dynamics (MD) simulations performed on RNA models mimicking the 2-DOS aminoglycoside binding site in the small ribosomal subunit. We also briefly discuss thermodynamics of interactions of these aminoglycosides with their 16S RNA target.
