Synthesis and biochemical properties of oligodeoxynucleotides acylated by the chemically stable 2-(trimethylsilyl)benzoyl (TMSBz) group at the 5′ or 3′ terminus
摘要:
Oligodeoxynucleotides acylated with a 2-(trimethylsilyl)benzoyl (TMSBz) group at the 5' or 3' terminus were synthesized according to the general method used for DNA synthesis. The acylated DNA oligomers could be easily purified due to the high lipophilicity of the TMSBz group and showed enhanced hybridization ability and resistance to exonucleases. (c) 2010 Elsevier Ltd.

report the synthesis and properties of nucleoside derivatives acylated by 2-(trimethylsilyl)benzoyl (TMSBz) that proved to be extremely stable under basic conditions when introduced into the 5′-hydroxyl group of thymidine, the 4-amino group of deoxycytidine and the 2′-hydroxyl group of uridine. In particular, 2′-O-TMSBz-uridine could be isolated and was more stable in pyridine, while it isomerized in CH2Cl2
我们报道了被2-(三甲基甲硅烷基)苯甲酰基(TMSBz)酰化的核苷衍生物的合成和性质,当将其引入胸苷的5'-羟基,脱氧胞苷的4-氨基和尿苷的2'-羟基。特别是,可以分离出2' - O -TMSBz-尿苷,并在吡啶中更稳定,而在Et 3 N存在下在CH 2 Cl 2中异构化,生成2'-O-和3'的混合物。 -O-酰化的物种。
