Na. Kurchavov et al., A NEW PHOSPHORAMIDITE REAGENT FOR THE INCORPORATION OF DIAZAPHENOXAZINONE NUCLEOSIDE WITH ENHANCED BASE-PAIRING PROPERTIES INTO OLIGODEOXYNUCLEOTIDES, Nucleosides & nucleotides, 16(10-11), 1997, pp. 1837-1846
New phosphoramidite reagent 7 suitable for incorporation of dC analogu
e was synthesized. ODNs containing diazaphenoxazinone residues in defi
ned positions were prepared. The stability of duplexes formed was incr
eased up to 3-5 degrees C per modified base. Preliminary results of mo
lecular biological testing were reported.
