Glucosamino nucleic acids (GANAs) bearing a β-N-glycoside bond between carbon 1 of the glucosamine and the nucleobase nitrogen were synthesized and incorporated into oligonucleotides (4′,6′-GANA and 3′,6′-GANA). The thermal stability of oligonucleotide duplexes containing the GANA zwitterionic nucleotides was also investigated.

用于稳定寡核苷酸的阳离子葡糖氨基核酸的合成

合成了在葡糖胺的碳1和核碱基氮之间带有β- N-糖苷键的葡糖氨基核酸（GANA），并将其掺入寡核苷酸（4'，6'-GANA和3'，6'-GANA）中。还研究了含有GANA两性离子核苷酸的寡核苷酸双链体的热稳定性。
