OLIGONUCLEOTIDE N3'-P5' PHOSPHORAMIDATES: SYNTHESIS AND COMPOUNDS; HYBRIDIZATION AND NUCLEASE RESISTANCE PROPERTIES |
摘要 |
Modified oligonucleotides 3'-NHP(O)(O-)O-5' phosphoramidates were synthesize d on a solid phase support. The phosphoramidate analogs were found to have significantly increased resistance toward phosphodiesterase digestion. Therm al dissociation experiments demonstrated that these compounds form more stable duplexes than phosphodiesters with complementary DNA and particularly RNA strands. Further, the phosphoramidate analogs can also form stable triplexes with double-stranded DNA target, where under similar conditions parent phosphodiester compounds failed to do so.
