摘要:
Incorporation of 5-propynylamino and 5-propynyl alpha-2'-deoxyuridine into alpha-oligonucleotides (a-ON) allows high-affinity targeting of complementary DNA for a-ON with anionic and neutral backbone but not for cationic a-ON, revealing clues on the role of the amino group of the propynylamino on the formation of DNA duplexes.
