摘要: 用磷酸三酯法在溶液中合成了两个带有3'-(S)-胸腺嘧啶基-4'-(R)一羟基-5'-(S)-羟甲基四氢呋喃的三脱氧核苷酸3和4. 与三脱氧核苷酸(2)相比,化合物3和4对核酸酶SI具有更大的稳定性.

关键词: 三脱氧核苷酸, 3&prime, -(S)-1-胸腺嘧啶基-4(R)-羟基-5&prime, -(S)-羟甲基四氢呋喃, 低聚核苷酸, 酶促稳定性

Abstract: Two trideoxynucleotides incorporated with 3'-(S)- (thymin-1-yl)-4'-(R) -hydroxy-5' -(S)-hydroxymethyl tetrahydrofuran in the 3' end (3) or in center (4) were synthesized via phos-photriester method in solution.Compounds 3 and 4 are stable towards Nuclease S1 compared withthe normal trideoxynucleotides (2).

Key words: Trideoxynucleotide, 3 '-(S)-(thymin-1-yl)-4'-(R)-hydroxy-5' -(S)-hydro-xymethyltetrahydrofuran, Oligonucleotide, Enzymatic stability
