Abstract
Herein, we reported the differential binding ability of aminoglycosides to DNA structures using electrochemical method through principal component analysis (PCA) to classify different DNA secondary structures and understand the link between secondary structure and DNA conformation. In these analyses, the DNA with different secondary structure motifs: bulge, internal loop, hairpin loop and stem loop were designed. The aminoglycosides as receptors were modified on the surface of electrode. In the presence of DNA, the DNA will be absorbed on the surface of electrode via the recognition of DNA and aminoglycosides, resulting in the electrochemical signal observed in [Fe(CN)6]3-/4-. Furthermore, the DNA structures labeled with 2-aminopurine (2-AP) at the structural motif of interest were also employed to study the binding affinity between aminoglycosides and different DNA motifs. The PCA suggested that this method may achieve nucleotide-specific classification of two independent secondary structure motifs, and the structure and sequence of DNA and the size and structure of small molecule could affect the binding ability of the aminoglycosides and DNA. This approach presents a new approach to classify DNA structure and offers ideas for designing targeted drugs small molecule compounds for wound dressing and drug delivery.

Abstract
Aminoglycosides, a class of antibiotics that includes gentamicin, kanamycin, neomycin, streptomycin, tobramycin and apramycin, are derived from various streptomyces species. Despite the significant increase in the antibacterial resistant pathogens, aminoglycosides remain an important class of antimicrobial drugs due to their unique chemical structure which offers a broad spectrum of activity. The modification of antibiotics and their subsequent use in supramolecular chemistry is rarely reported. Given the importance of aminoglycosides, here we give a brief overview on the modification of 4,5- and 4,6-disubstituted deoxystreptamine classes of aminoglycosides through supramolecular chemistry and their potential for real world applications. We also make the case that the work in this area is gaining momentum, and there are significant opportunities to meet the challenges of modern antibiotics through the modification of aminoglycosides by harnessing the advantages of supramolecular chemistry.
