Abstract

XdT12 and dT5XdT6, where X is 1-(4'-thio-beta-d-ribofuranosyl)-thymine, were synthesized. The first oligonucleotide presents a better stability against calf spleen phosphodiesterase than natural dT12. The second one hybridizes with complementary sequence. However the X:A base pairing stability is lower than natural T:A one.

摘要

合成了XdT12和dT5XdT6,其中X为1-(4'-硫代-β-D-呋喃核糖基)-胸腺嘧啶。与天然的dT12相比,第一种寡核苷酸对小牛脾磷酸二酯酶表现出更好的稳定性。第二种寡核苷酸能与互补序列杂交。然而,X:A碱基对的稳定性低于天然的T:A碱基对。
