G. Balow et al., POSITIONING OF FUNCTIONALITIES IN A HETERODUPLEX MAJOR GROOVE - SYNTHESIS OF 7-DEAZA-2-AMINO-2'-DEOXYADENOSINES, Nucleosides & nucleotides, 16(7-9), 1997, pp. 941-944
We have synthesized the 7-iodo-, 7-cyano- and 7-propynyl-7-deaza-2-ami
no-2'-deoxyadenosines and incorporated each into several oligonucleoti
de (ODN) sequences. These oligonucleotides exhibit enhanced binding af
finities to RNA complements relative to unmodified sequences.
