It is an object to provide a nucleoside analog that can produce an oligonucleotide analog in which the two properties of chemical and biological stability, and the ability to form double strands, are excellent, and an oligonucleotide analog that includes that nucleoside analog. This is achieved by a nucleoside analog or salt thereof represented by Formula (I) below, in which, in Formula (I), R
1
is any group selected from the group consisting of the group of Formula (1), the group of Formula (2), the group of Formula (3), the group of Formula (4), the group of Formula (5), the group of Formula (6), the group of Formula (7), the group of Formula (8), and any of these groups whose functional group has been protected by a protecting group, and k, l, m, and n are each independently an integer from 1 to 10.
本发明旨在提供一种能够产生化学和生物稳定性以及形成双链的寡核苷酸类似物的核苷酸类似物,以及包括该核苷酸类似物的寡核苷酸类似物。通过下式(I)所表示的核苷酸类似物或其盐来实现这一目的,在式(I)中,R1是从式(1)的群组,式(2)的群组,式(3)的群组,式(4)的群组,式(5)的群组,式(6)的群组,式(7)的群组,式(8)的群组以及这些群组中任何一个的群组中选择的任何群组,其官能团已被保护基所保护,而k,l,m和n各自独立地是从1到10的整数。
