    摘要： Functionalized nucleomonomers and oligonucleotides are provided which have increased nuclease resistance and enhanced binding affinity to target DNA or RNA molecules. The oligonucleotides of the present invention comprise at least one 7-deaza-7-iodo-2'-substituted purine, herein referred to as a functionalized nucleomonomer. A preferred 2' substituent on the sugar moiety is a 2'-O-alkoxy alkyl group. More preferably, the 2'-substituent is 2'--O--CH.sub.2 --CH.sub.2 --O--CH.sub.3 (or 2'-methoxyethoxy). Such oligonucleotides are useful as therapeutics for modulating protein expression in organisms and treating disease states susceptible to oligonucleotide therapeutics. Such oligonucleotides are also useful as diagnostics for the diagnosis and detection of disease states, and as research reagents.
