Bform Dna Recognition By Neomycin Conjugates

To date, few carbohydrate interactions with DNA have involved interactions within the major groove. Among the classes of compounds known to exhibit DNA binding are enediyne antibiotics, anthracyclines, pluramycins, indolocar-bazoles, and aureolic acids.8 Of the limited number of carbohydrates known for DNA binding, only a select few have displayed major groove contacts. These

TABLE 11.1. Association Constants of Various Nucleic Acids with Neomycin. From top to bottom, various polynucleotides with their conformational preference (B- to A-form) are listed in 10 mM sodium cacodylate, 100 mM NaCl, 0.1 mM EDTA, pH 6.8. RNA targets that have previously been shown to bind neomycin are also listed. These targets are examples of RNA secondary structures that show high-affinity binding to aminoglycosides. Solution conditions for RNA targets vary as shown
