Hw. Yu et al., SYNTHESIS AND ENZYMATIC STABILITY OF OLIGONUCLEOTIDE INCORPORATED WITH ISONUCLEOSIDE, Gaodeng xuexiao huaxue xuebao, 18(7), 1997, pp. 1103-1106
Two trideoxynucleotides incorporated with -(thymin-1-yl)-4'-(R)-hydrox
y-5'-(S)-hydroxymethyl tetrahydrofuran in the 3' end (3) or in center
(4) were synthesized via phosphotriester method in solution. Compounds
3 and 4 are stable towards Nuclease S1 compared with the normal tride
oxynucleotides (2).
