Title:
CROSSLINKED NUCLEOSIDE AND NUCLEOTIDE
Document Type and Number:
WIPO Patent Application WO/2015/125783
Kind Code:
A1
Abstract:
Disclosed are a crosslinked nucleoside and nucleotide. The nucleoside has a 2',4'-crosslinked structure, and is represented by formula (I). An oligonucleotide containing a 2',4'-crosslinked artificial nucleotide according to the present invention has nuclease resistance exceeding that of LNA and a binding affinity to single-strand RNA comparable to publically known 2',4'-BNA/LNA. In particular, use in a nucleic acid drug is anticipated due to the strong binding affinity to single-strand RNA in comparison to S-oligos.
