An oligo- or polynucleotide analogue having one or more structures of the general formula
1
where B is a pyrimidine or purine nucleic acid base,
or an analogue thereof,
is disclosed. The use of this analogue provides an oligonucleotide analogue antisense molecule, which is minimally hydrolyzable with an enzyme in vivo, has a high sense strand binding ability, and is easily synthesized.
揭示了一种具有通式1的寡核苷酸或多核苷酸类似物,其中B是
嘧啶或
嘌呤核酸碱基,或其类似物。该类似物的使用提供了一种寡核苷酸类似物反义分子,在体内具有最小的
水解能力,具有高的sense链结合能力,并且易于合成。
