Synthesis of Aminoglycoside-Modified Oligonucleotides

Abstract

[structure: see text] To study the structural requirements of aminoglycoside binding to nucleic acids, compound 1-an analogue of the naturally occurring nucleoside J-was synthesized. When incorporated into oligodeoxynucleotides, 1 leads to thermal stabilization of the resulting duplexes. The increase in pairing affinity is stronger with complementary RNA than with DNA.
